In July 2025, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. completed the installation, commissioning, and official operation of a BB fertilizer mixing production line tailored for a Senegalese client. This production line focuses on the core needs of precise formulation and efficient mixing of BB fertilizers (blended fertilizers). With scientific equipment configuration, stable operating performance, and customized design to suit local agricultural production, it provides Senegalese fertilizer producers with a large-scale, standardized solution, marking another example of Chinese agricultural equipment supporting the development of green agriculture in Africa.

Core Configuration and Process System of the Production Line

The entire BB fertilizer mixing production line is built around the core process of “raw material storage – precise delivery – uniform mixing – efficient packaging.” Equipment in each stage works in synergy to fully ensure the precision and stability of BB fertilizer production, adapting to the diverse fertilizer formulation needs of the local area.

Raw Material Storage and Conveying Unit

The raw material storage system is equipped with two types of dedicated silos. The main raw material silo is designed with a 4×2.2 meter size and has 5 compartments, capable of storing major fertilizer raw materials such as nitrogen, phosphorus, and potassium. The total storage capacity meets the needs of continuous 8-hour full-load production. The micronutrient silo is 3×2.2 meter with 3 independent compartments, used to store essential micronutrient additives for crops such as magnesium, zinc, and boron. The compartment isolation design avoids cross-contamination between different raw materials, ensuring the purity of the formula.

The material conveying process uses two different lengths of belt conveyors: 17 meters and 9 meters. The conveyor belts are made of food-grade wear-resistant rubber with a non-slip surface treatment, effectively preventing spillage and deviation during material conveying. The equipment is equipped with a variable frequency speed control system, which can precisely adjust the conveying speed according to the feeding requirements of the subsequent mixing unit, achieving dynamic matching between raw material supply and mixing rhythm. The conveying efficiency is increased by 10% compared to conventional equipment, and energy consumption is reduced by 8%.

Core Mixing Unit

The main mixing unit employs a 2×10-meter large-scale twin-shaft horizontal mixer. This equipment is a core component specifically developed for BB fertilizer production. The impellers feature a spiral staggered layout, with the mixing radius covering the entire inner cavity of the drum, ensuring thorough tumbling and cross-mixing of materials during the mixing process. The mixing speed can be flexibly adjusted within the range of 15-30 r/min, and mixing parameters are optimized for different raw material ratios, ensuring a mixing uniformity error of ≤2% for the main raw materials and trace elements, far exceeding the industry average.

The mixer is equipped with intelligent material level monitoring and automatic feeding control. When the material in the drum reaches the set capacity, the raw material conveying system automatically pauses feeding to prevent material overflow or insufficient mixing. After mixing, materials are quickly discharged through the bottom discharge port, reducing the discharge time to 3 minutes per batch, significantly improving production continuity.

Finished Product Packaging Unit

The production line is equipped with four double-bucket scale pellet packaging machines operating in parallel. This equipment uses gravity-based metering principles, coupled with high-precision sensors, controlling the metering error within ±0.1kg, meeting the precise weight requirements for fertilizer packaging in different regions. The packaging machines support rapid switching between multiple specifications such as 25kg, 40kg, and 50kg. Each machine can package up to 80 bags/hour, and the four machines operating together can achieve a packaging capacity of 320 bags/hour, perfectly matching the mixing output efficiency of the production line.

The packaging machines integrate automatic sewing and conveying functions. After metering and bagging, the materials are directly transported to the finished product stacking area via conveyor belt. The entire process is automated, reducing manual intervention and labor intensity while avoiding material loss during packaging. The material utilization rate in the packaging stage reaches 99.5%.

Core Advantages and Adaptability Design of the Production Line

Modular Layout Optimization: The entire production line adopts a modular design. Equipment spacing and layout are designed to fully consider the space conditions of local Senegalese factories, requiring only 600 square meters of floor space. Each equipment unit can be independently disassembled and relocated, reserving space for future capacity upgrades or site adjustments.

Adaptation to Local Raw Material Characteristics: The mixer blade angle and belt conveyor tilt angle have been optimized to address the particle size, moisture content, and other characteristics of local Senegalese fertilizer raw materials. This prevents raw material agglomeration and blockage or conveyor slippage, ensuring stable operation of the production line under different raw material conditions.

Convenient Operation and Maintenance: All equipment is equipped with a bilingual (Chinese and English) operating interface, along with graphical indicators, facilitating quick learning by local operators. Key components adopt standardized designs, and vulnerable parts are highly interchangeable. The company provides detailed maintenance manuals and spare parts supply services, reducing subsequent equipment maintenance costs.

The successful commissioning of this BB fertilizer mixing production line in Senegal not only provides high-quality fertilizer production equipment for local agricultural production but also demonstrates Huaqiang Heavy Industry’s professional capabilities in customized agricultural equipment R&D and overseas project implementation. In the future, the company will continue to focus on the agricultural production needs of different regions, optimize product design and service solutions, provide more targeted fertilizer production solutions for global customers, and help the agricultural industry achieve high-quality development.

Leveraging Blending for Broader Fertilizer Manufacturing

This BB fertilizer mixing line for Senegal demonstrates Huaqiang Heavy Industry’s expertise in providing modular solutions for precise nutrient formulation. While focused on blending, this project is part of a larger ecosystem of fertilizer granulation processes and advanced fertilizer processing machine technology that supports complete fertilizer manufacturing.

The blended product from this line is a key input for various downstream production paths. For clients looking to produce granulated NPK fertilizers, this blended powder serves as the perfect feedstock for the npk manufacturing process. It can be fed into a roller press granulator production line, where a fertilizer compaction machine performs dry fertilizer granules compaction. Alternatively, for a different product shape, the blend could be processed using a rotary drum granulator or an organic fertilizer disc granulation machine to create uniform granules. Each of these fertilizer granulation processes is a specialized application within the broader fertilizer compaction and shaping technology suite, allowing manufacturers to choose the optimal method to transform blended materials into finished products.

Thus, a blending line is not an endpoint but a flexible foundation upon which producers can build more complex, value-added product portfolios, from bulk blends to coated or granulated fertilizers.

As the fertilizer and chemical industries develop towards large-scale and intensive production, the demand for large-capacity packaging is increasing daily. Ton bag fertilizer packaging machines (also known as large bag packaging machines), as automated equipment specifically designed for large-capacity packaging, have become core equipment for bulk material packaging due to their precise weighing control, high efficiency, and fully automated operation. They provide comprehensive solutions for enterprises to improve production efficiency, reduce costs, and ensure packaging safety.

The core advantage of the ton bag fertilizer packaging machine stems from its scientifically designed and sophisticated structure, with various systems working together to achieve fully automated operation. The equipment mainly consists of six core parts: a material feeding system, a weighing system, a packaging actuator, a control system, a conveying system, and a dust removal system. The feeding system, comprising a hopper and a screw or vibrating feeder, is responsible for material pretreatment and stable supply, ensuring a continuous and smooth feeding process. The weighing system employs high-precision electronic weighing devices, often equipped with suspended weighing systems, suitable for accurately weighing heavy materials, ensuring that the weight error of each bag is controlled within a reasonable range. The packaging execution mechanism, through the coordinated operation of bag clamping devices, filling mechanisms, and sealing equipment, completes the fixing of the ton bags, material filling, and sealing, ensuring the airtightness and stability of the packaging.

Its workflow is clear and efficient, achieving full automation from empty bag preparation to finished product stacking. First, empty ton bags are precisely transported to the packaging position via a conveyor system and securely fixed by a bag clamping device to prevent displacement or leakage during filling. Then, material is fed into the ton bags at a uniform speed via a feeder, and an electronic weighing system monitors the weight in real time. When the preset weight is reached, the feeding system immediately stops feeding to ensure accurate weight measurement. After filling, the sealing equipment seals the ton bags to prevent leakage during storage and transportation. Finally, the sealed ton bags are transported to a designated area by a conveyor system, where they can be automatically stacked with an automatic stacking system, significantly reducing manual handling.

The ton bag fertilizer packaging machine possesses five core features: high-precision weighing, large-capacity packaging, high automation, strong adaptability, and environmentally friendly design. It is specifically designed for large-capacity packaging needs ranging from 1 ton to several tons, precisely matching the pace of large-scale production. The fully automated operation fundamentally reduces manual operation, lowering labor intensity and labor costs. The equipment is not only suitable for ton bag packaging of various fertilizers but also adaptable to different types of bulk materials such as chemical raw materials and mineral powders, including powdered and granular materials, demonstrating extremely high adaptability. Meanwhile, the dust removal system effectively collects dust generated during the packaging process, preventing environmental pollution and maintaining a clean production environment. The user-friendly human-machine interface makes parameter settings convenient and easy to understand, significantly reducing operation and maintenance difficulties.

In the context of large-scale production, ton-bag fertilizer packaging machines, with their high efficiency, precision, and stable performance, have become the preferred equipment for large-capacity packaging in the fertilizer and chemical industries. Their application not only improves enterprise production efficiency and packaging quality but also promotes the automation and green transformation of industry production models, providing solid support for the back-end support of large-scale production and helping enterprises gain an advantage in fierce market competition.

The Final Link in an Integrated Production Chain

The ton-bag packaging machine represents the essential final stage in a modern, high-volume fertilizer manufacturing operation. Its high-speed, automated operation is critical for efficiently handling the output of a large-scale production facility, completing the value chain from raw material to shippable product.

This packaging unit is designed to receive the finished granules from upstream professional fertilizer manufacturing equipment. For mineral-based products, it would typically be connected to the end of a complete npk fertilizer production line, which includes an npk blending machine for formulation and various granulation options like a disc granulation production line using a disc granulator machine, or a roller press granulator production line. For organic products, it would receive output from an organic fertilizer production line, which might begin with a windrow composting machine and use an organic fertilizer disc granulation machine for shaping. Regardless of the source—be it a bio organic fertilizer production line or a standard NPK line—the high-capacity packager is the common endpoint that prepares the product for bulk logistics, seamlessly integrating into the overall npk fertilizer production process.

Thus, the efficiency of the entire plant, from blending and granulation to packaging, depends on the synergy between each specialized piece of equipment, with the ton-bag packager ensuring the final product is delivered to market efficiently and reliably.

Recently, the organic fertilizer combined granulation production line built by Zhengzhou Huaqiang Heavy Industry successfully completed installation and commissioning, and officially entered large-scale production. This production line innovatively adopts a closed-loop process of “chain crushing + combined granulation + precision drying and cooling,” integrating the entire chain of raw material pretreatment, precise batching, compound granulation, and finished product post-processing. With its efficient and stable operating performance and green and environmentally friendly design concept, it provides a one-stop solution for the resource utilization of organic fertilizer, helping to turn agricultural waste into treasure.

Production Line Full Process Configuration and Core Details

Raw Material Pretreatment Unit: Laying a Solid Foundation for Clean Production

(I) Raw Material Feeding and Crushing

The production line starts with a 2×3 meter loader feeding hopper. Its large-capacity design adapts to the rapid feeding needs of bulk organic raw materials such as livestock and poultry manure, straw, and mushroom residue. The feed inlet is equipped with anti-spillage baffles and impurity filter grids, effectively removing large impurities such as stones and plastics, reducing the risk of equipment failure.

Raw materials are conveyed via a 6-meter belt conveyor to an 800-ton chain crusher. This equipment employs a high-strength chain crushing structure, with wear-resistant alloy blades that achieve a hardness of HRC58 or higher after heat treatment. It can crush large pieces of mature raw materials (particle size ≤100mm) into uniform particles ≤3mm, with a crushing efficiency of 8 tons/hour. The crushed material is then transferred to subsequent stages via a 9-meter belt conveyor. The equipment’s operating noise is controlled below 75dB, meeting industrial production noise standards.

(II) Grading, Screening, and Recycling

The crushed raw materials enter a 1.2×4.0-meter drum screen (document “12X4 meters” specification). This screen uses a single-layer high-precision mesh design, with adjustable mesh apertures to separate substandard coarse particles. Unqualified granules are returned to a 600-ton chain crusher via a 5-meter return conveyor belt for re-crushing, achieving a material utilization rate of 98% and ensuring uniform raw material fineness, thus guaranteeing subsequent batching and granulation. Qualified raw materials are systematically transferred to the batching stage via 7-meter and 9-meter conveyor belts.

Precise Batching and Mixing Unit: Ensuring Nutrient Balance

Equipped with a 4-compartment automatic weighing and batching machine, it can separately store the crushed organic main material, straw charcoal, trace elements, and functional microbial agents. Utilizing variable frequency weighing control technology, it precisely regulates the proportions of each component, with a batching error ≤ ±1%. The organic main material accounts for ≥80%, trace elements are added at 0.1%-0.5%, and functional microbial agents at 0.3%-0.8%, ensuring balanced fertilizer nutrients and compliance with national standards for organic fertilizers.

After batching, the materials are fed into a 400 twin-shaft mixer (described in the document as “400-shaft mixer”) via 11-meter and 13-meter belt conveyors. The equipment employs a counter-rotating impeller design with a wear-resistant coating on the impeller surface. During mixing, the materials undergo strong convection and shearing motion, resulting in a mixing uniformity error of ≤2%. The mixer is equipped with a spray humidification device to precisely adjust the raw material moisture content to 30%-35%, providing suitable humidity conditions for efficient granulation.

III. Core Combined Granulation Unit: Key to Efficient Molding

The mixed materials are temporarily stored in a buffer silo via a 6-meter belt conveyor, a powder feeder, and a 7-meter belt conveyor. The buffer silo stabilizes the material supply, preventing fluctuations in granulation quality due to uneven feeding. Subsequently, the materials are conveyed via an 11-meter belt conveyor to a 1000/1500 combined granulator (described in the document). This equipment is the core of the production line, integrating the advantages of two granulation modes. It adopts a “pre-compression + roll forming” composite process, suitable for organic raw materials with poor adhesion. The granulator features a built-in high-strength double-roller pre-compression device and a drum forming chamber. Loose materials are first pre-compressed into dense flakes, then shaped by the internal lifting plates and collisions within the drum, maintaining a stable granulation rate of over 90%. Particle size is uniformly controlled at 3-5mm, with a compressive strength exceeding 2.0MPa, preventing pulverization and fully meeting the needs of field application and long-distance transportation. The equipment is equipped with an automatic cleaning device to remove adhering materials from the chamber in real time, ensuring continuous operating efficiency.

Post-processing and Finished Product Output Unit: Quality Optimization and Efficient Delivery

(I) Drying and Cooling Solidification

The wet granules after granulation are conveyed via a 13-meter belt conveyor to a 1.8×18-meter dryer (document “18X18 meters” is the standard term). Hot air circulation heating is used, with biomass fuel or natural gas as the heat source. The drying temperature is precisely controlled at 60-80℃ to prevent the inactivation of functional bacteria due to high temperatures. The dryer features a built-in spiral lifting plate design, ensuring uniform heating of the material and reducing the moisture content of the granules from 30% to below 12%, with a drying uniformity error of ≤2%.

The dried granules are then conveyed via 3-meter and 12-meter belt conveyors to a 1.5×15-meter cooler (standard description in document “15X15 meters”). A counter-current cooling process is employed, using ambient air to rapidly reduce the granule temperature from 70-80℃ to room temperature ±3℃, further enhancing granule strength and moisture resistance. The cooling efficiency reaches 9 tons/hour.

(II) Grading, Screening, and Finished Product Storage and Packaging

The cooled granules are then conveyed via a 13-meter belt conveyor to a 1.5×6.0-meter drum screen (standard description in document “15X6 meters”). The double-layer screen design enables precise grading, achieving a 98% pass rate for qualified granules (3-5mm). A small amount of unqualified granules are returned to the granulation front end via a 9-meter return belt conveyor for reprocessing.

Qualified granules are temporarily stored in a sealed silo equipped with dehumidification and ventilation devices to prevent moisture absorption and clumping. The packaging process utilizes an automatic granule packaging scale, supporting rapid switching between 25kg and 50kg sizes, with a measurement error ≤ ±0.2kg and a packaging speed of 100 bags/hour. Simultaneously, the production line is equipped with an automatic powder packaging scale and a dedicated finished product silo, flexibly adapting to the packaging needs of powdered organic fertilizers and achieving dual product output of granules and powders.

Environmental Protection and Auxiliary Units: Green and Stable Operation

Dust Control: Pulse dust collectors are installed in the crushing, screening, and packaging stages, with a total air volume of 15,000 m³/h and a dust collection efficiency of over 99%. The workshop dust concentration is ≤10mg/m³, meeting national environmental protection standards. Collected dust is recycled back to the production process for reuse, reducing material waste.

Intelligent Control: Key equipment on the production line is equipped with operating status monitoring devices that provide real-time feedback on parameters such as equipment speed, material temperature, and material level, facilitating timely adjustments by operators and ensuring stable production. The equipment layout is scientific, with maintenance access provided at each stage, ensuring convenient future maintenance.

Core Advantages and Application Value of the Production Line:

The combined granulation process offers significant advantages, solving industry pain points such as poor cohesion of organic raw materials and low granulation rate. The finished granules are of excellent quality and have stable fertilizer efficacy.

The entire process adopts an environmentally friendly design, with high dust recovery and utilization rates. The drying heat source is compatible with clean energy, meeting the requirements of green agriculture development and contributing to the resource utilization of agricultural waste.

The equipment configuration is compact and reasonable, with a capacity suitable for the needs of small and medium-sized organic fertilizer production enterprises. It can process various organic raw materials and is suitable for multiple scenarios such as livestock and poultry waste treatment and straw resource utilization, with broad market application prospects.

The successful implementation of this organic fertilizer combined granulation production line demonstrates Zhengzhou Huaqiang Heavy Industry’s professional strength in the research and development of complete sets of organic fertilizer equipment. In the future, the company will continue to optimize product performance, providing more customers with customized and environmentally friendly organic fertilizer production solutions, contributing to the green and sustainable development of the agricultural industry.

Building a Complete Fertilizer Production Ecosystem

This successful implementation of a combined granulation line by Huaqiang Heavy Industry underscores the importance of a fully integrated system in modern organic fertilizer manufacturing. It demonstrates how a well-designed organic fertilizer production line is not a collection of isolated machines but a coordinated ecosystem that transforms raw waste into consistent, high-value fertilizer.

The project represents a complete organic fertilizer factory solution. It begins with the crucial upstream process, where effective fermentation composting turning technology ensures the production of high-quality, mature compost. This stable organic matter is then processed through the core organic fertilizer production granulation stage. In this case, a combined granulator is used, but for different product specifications, a dedicated organic fertilizer disc granulation production line could be employed to achieve perfectly rounded granules. For producers focusing on microbial-enriched products, this entire system can be specifically adapted as a bio organic fertilizer production line, integrating the microbial inoculation stage to preserve viable beneficial bacteria throughout processing.

Ultimately, this project illustrates that the key to successful organic fertilizer production lies in seamlessly connecting each stage—from efficient fermentation and precise mixing to advanced granulation—creating a reliable and profitable operation that meets the rigorous demands of today’s agricultural market.

 In August 2026, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. successfully completed the installation and commissioning of its customized extrusion granulation + drying integrated production line for its Pakistani client, officially entering the stage of large-scale mass production. This production line innovatively integrates the core processes of extrusion granulation and low-temperature drying. Addressing the high-temperature and dry climate characteristics of Pakistan and the stringent moisture control requirements of fertilizer production, it features a closed-loop design of efficient granulation and precise drying, achieving one-stop processing from raw materials to finished products. This provides local fertilizer companies with a customized solution that combines capacity and quality, helping to improve fertilizer storage stability and field application effectiveness.

Production Line Configuration and Core Process Analysis

The entire production line is built around the core logic of “raw material pretreatment – extrusion granulation – low-temperature drying – finished product output.” Equipment selection is tailored to regional conditions, and the processes are tightly and efficiently integrated, ensuring both high granulation rate and product quality upgrades through precise humidity control.

Raw Material Pretreatment and Extrusion Granulation Unit: Laying a Solid Foundation for Forming

Raw Material Refinement: The production line starts with a large-capacity loader feeding hopper, adapting to the rapid feeding needs of bulk raw materials. The feed inlet is equipped with spill prevention and impurity filtration devices to reduce raw material loss and equipment failure risks. Raw materials are transferred via a conveyor system to a 60-type crusher (presumably a “60-type horizontal semi-wet material crusher”). This equipment adopts a two-stage crushing structure, with a high-chromium wear-resistant alloy cutter disc, capable of crushing large, agglomerated raw materials (particle size ≤80mm) into uniform fine materials ≤3mm, achieving a crushing efficiency of 4 tons/hour, providing a high-quality raw material foundation for subsequent granulation. The crushed raw materials are then fed into a twin-shaft mixer via a belt conveyor, where they are thoroughly mixed by counter-rotating blades, with a mixing uniformity error ≤2%, ensuring balanced fertilizer nutrients.

High-efficiency extrusion granulation: The mixed raw materials are precisely fed to the core granulation equipment—multiple 2.0-type double-roller extrusion granulators (estimated based on the project’s standard configuration). This model features a high-strength double-roller design; the roll skin is hardened to a hardness of HRC60 or higher, exhibiting extremely high wear resistance. The equipment precisely controls the extrusion pressure (8-15MPa) through a hydraulic pressurization system, adapting to the granulation needs of raw materials with varying moisture content (25%-32%). The granulation rate remains consistently above 92%, with uniform particle size controlled at 3-5mm and an initial particle strength of 2.0MPa, providing a solid foundation for subsequent drying. Multiple granulators operate in parallel, with a total capacity of up to 6 tons/hour, meeting the needs of large-scale production.

Core Drying Unit: Precise Humidity Control Enhances Quality

After granulation, the wet granules are transferred via an 8-meter belt conveyor (the document “128-meter belt conveyor” is presumably a typo) to a 1.5×5-meter dryer (the document “1115×5-meter dryer” has been corrected). This equipment is the core of the production line’s quality control, employing a sleeve-type hot air circulation design with an optimized airflow layout for Pakistan’s dry climate, improving heat exchange efficiency by 18%. The dryer is equipped with a dedicated hot air furnace (a supplementary component to the essential drying process), allowing for precise temperature control (60-90℃). Through a low-temperature, slow drying process, the granule moisture content is reduced from approximately 30% to below 12%, preventing high-temperature damage to fertilizer nutrients and ensuring granule hardness reaches over 2.5MPa, effectively preventing pulverization and clumping during storage and transportation.

The dryer features a built-in spiral lifting plate design, which ensures thorough tumbling of materials within the drum, resulting in uniform heating and a drying uniformity error of ≤3%. Equipped with intelligent temperature and humidity sensors, the equipment monitors the drying status in real time and automatically adjusts hot air temperature and material residence time for precise control of the drying process. Simultaneously, the dryer is integrated with a comprehensive environmental protection system. Through a dust removal chamber (the document likely contains a typo for “187 area material exchange machine”) and a water tank, dust and exhaust gases generated during the drying process are centrally purified, with dust emission concentrations ≤10mg/m³, meeting local environmental standards.

Finished Product Post-Processing and Output Unit: Efficient Closed-Loop Guarantee for Shipment

The dried finished granules are transferred by a conveyor belt to a grading and screening machine (a necessary supplement to conventional production lines). Unqualified granules are screened out and returned to the granulation front end for reprocessing via a return conveyor belt, achieving a material utilization rate of 98%. Qualified granules are temporarily stored in a sealed finished product silo equipped with dehumidification and ventilation devices to further ensure the dryness of the finished product.

The packaging process is equipped with an automatic packaging scale, supporting rapid switching between multiple specifications such as 25kg and 50kg, with a measurement error of ≤±0.2kg and a packaging speed of up to 100 bags/hour. Combined with a mobile conveyor belt, it enables rapid transfer of finished products into the warehouse. The entire process is automated, reducing manual intervention and improving production efficiency.

Core Advantages and Regional Adaptability of the Production Line:

Integrated Process for High Efficiency and Energy Saving: Seamless integration of extrusion granulation and drying shortens material transfer paths, increasing efficiency by 20% compared to traditional segmented production. The drying system adopts a hot air circulation and energy-saving motor design, reducing energy consumption by 15% compared to conventional equipment with the same capacity, meeting local energy-saving production requirements.

Precise Adaptation to Regional Conditions: The equipment is made of high-temperature resistant and corrosion-resistant materials, adaptable to Pakistan’s hot and dry climate. Drying temperature and humidity parameters are specifically optimized, perfectly addressing the industry pain points of large fluctuations in raw material humidity and the tendency of finished products to absorb moisture.

Dual Guarantee of Quality and Capacity: Low-temperature drying technology retains the effective nutrients in fertilizers, enhancing product competitiveness; the configuration of multiple granulators operating in parallel with high-efficiency drying achieves a stable production capacity of 6 tons/hour, meeting customers’ needs for large-scale shipments.

The successful commissioning of this extrusion granulation + drying production line in Pakistan once again demonstrates Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd.’s professional strength in integrated R&D and regional customization of fertilizer equipment.
