In the drying and cooling stages of the organic fertilizer production line, drum fertilizer dryers and drum fertilizer coolers have become key equipment for achieving large-scale production due to their stable and efficient performance. The two are seamlessly connected to jointly ensure the quality of organic fertilizer products and production efficiency.

The drum fertilizer dryer is essential for dehydrating and shaping organic fertilizer. The moisture content of fermented organic fertilizer can reach as high as 50%-60%, requiring treatment in the drum dryer to reduce it to a safe storage range of 15%-20%. This equipment utilizes an inclined drum structure. External heating or hot air penetration ensures continuous tumbling of the material within the drum, ensuring full contact with the heat source. During operation, the hot air temperature must be precisely controlled at 60-80°C, ensuring rapid water evaporation while preventing high temperatures from damaging beneficial microorganisms such as Bacillus subtilis and lactic acid bacteria, as well as organic matter in the organic fertilizer. Furthermore, the drum dryer’s sealed design and exhaust gas recovery system effectively reduce dust and volatile gas emissions, meeting environmental standards and adapting to the needs of production lines of varying sizes. The drum cooler is a key piece of equipment for cooling and improving the quality of dried materials. The temperature of dried organic fertilizer can reach 40-50°C. Direct packaging can easily generate condensation, leading to clumping.

The drum fertilizer cooler utilizes a countercurrent heat exchange principle. Cool air enters from one end of the drum and contacts the hot material at the other end. As the material rotates, it efficiently cools the material, keeping it within +5°C of the ambient temperature. Its unique internal lifting plate structure ensures uniform material agitation and cooling, while further removing any residual free moisture. This loosens the organic fertilizer particles, improving product flowability and appearance. Furthermore, the drum cooler’s enclosed design reduces dust spillage, minimizing dust pollution in the production environment and ensuring smooth subsequent screening and packaging processes.

The synergistic application of the drum fertilizer dryer and drum fertilizer cooler creates an efficient and stable drying and cooling system for the organic fertilizer production line. By rationally matching equipment parameters and process conditions, we can maximize the retention of organic fertilizer nutrients and biological activity, improve production efficiency, reduce energy consumption and losses, provide high-quality and stable organic fertilizer products for the agricultural field, and promote the development of green agriculture.

Problems and Solutions in Bio-Organic Fertilizer Production Lines

Written by fertilizer production line on September 22nd, 2025. Leave a comment

During the production process, bio-organic fertilizer production lines often face various problems that affect product quality and production efficiency, requiring precise identification and proper resolution.

Two major issues are common in the raw material processing phase. First, an imbalance in the raw material ratio. If the ratio of livestock and poultry manure to straw is inappropriate, the carbon-nitrogen ratio will deviate from the optimal range (25:1-30:1), thereby affecting fermentation efficiency. For example, excessive straw will slow fermentation, while excessive manure will easily produce a foul odor. The solution is to strictly adjust the ratio according to test data and regularly test the raw material composition. Second, excessive raw material impurities. Impurities such as soil and gravel can damage subsequent equipment and reduce the purity of the organic fertilizer. A vibrating screen should be installed at the raw material inlet to preemptively remove impurities.

The fermentation stage of a bio-organic fertilizer production line is crucial. Common problems include abnormal fermentation temperatures and incomplete composting. Excessively high temperatures (over 70°C) kill beneficial microorganisms, while temperatures that are too low cannot effectively kill harmful bacteria and insect eggs. Temperature control requires adjusting ventilation and the frequency of the compost turning machine. For example, increase ventilation when the temperature is too high, reduce ventilation when it is too low, and cover with insulation film. Incompletely composted organic fertilizer, when applied to the soil, will ferment again, potentially burning crop roots. This can be addressed by extending the fermentation time until the material turns dark brown and has no noticeable odor before proceeding to the next step.

Common equipment operation issues include conveyor blockage and reduced grinder efficiency. Conveyor blockage is often caused by excessive moisture content or excessive feed rate. The moisture content of the raw materials should be controlled between 50% and 60%, and the feed rate should be adjusted according to the equipment’s capacity. Reduced grinder efficiency is often caused by blade wear or screen blockage. Blade wear should be regularly inspected and replaced, and the screen should be cleaned of impurities.

Product quality issues primarily arise from excessive moisture content and uneven nutrient distribution. Excessive moisture content can lead to clumping and mold in the finished product. Drying parameters should be optimized to ensure the moisture content is below 15%. Uneven nutrient distribution is related to insufficient mixing of raw materials. High-efficiency mixing equipment should be used in the mixing process to extend the mixing time and ensure uniform mixing of materials.

Advantages of Rotary Drum Granulators over Disc Granulators

Written by fertilizer production line on September 22nd, 2025. Leave a comment

When selecting organic fertilizer granulation equipment, both rotary drum and disc granulators are commonly used. However, rotary drum granulators, with their multi-dimensional performance advantages, better meet the efficiency and scale requirements of modern organic fertilizer production lines. The differences between the two are primarily reflected in the following four aspects.

More flexible capacity adaptability meets the needs of large-scale production. Disc granulators are limited by the diameter of their discs, typically with an hourly output of 0.5-5 tons per unit, making them suitable only for small production lines. By adjusting the drum length and diameter, rotary drum granulators can achieve hourly outputs of 1-20 tons per unit. They meet the basic production needs of small and medium-sized enterprises as well as the large-scale production of large factories. They eliminate the need for multiple units in parallel, reducing production line floor space and equipment investment costs.

They offer greater raw material compatibility and reduce pretreatment complexity. Organic fertilizer raw materials have large fluctuations in moisture and composition. Disc granulators must maintain a moisture content of 20%-30%. They also struggle with crude fiber materials, which tend to stick to the disc and produce uneven granules. Rotary drum granulators can process materials with moisture levels of 25%-40%. Leveraging the multi-directional force of the rotating drum, they can smoothly granulate composted straw, livestock manure, and other materials without the need for additional crushing or conditioning, streamlining the process.

The resulting product is more stable and meets standardized requirements. Due to the single direction of centrifugal force, disc granulators produce pellets with a roundness of 70%-80% and large particle size variations. Rotary drum granulators, on the other hand, utilize internal rollers to guide and rotate the pellets, resulting in a fully rolling and shaping process with a roundness exceeding 90% and a precisely controlled particle size of 2-5mm. Furthermore, the granulation process is gentle, does not damage organic matter, and the pellets are of moderate strength. Transportation losses are 15%-20% lower than those from disc granulators.

Operation and maintenance are also simplified, resulting in lower long-term costs. Disc granulators require frequent manual adjustments of inclination and speed, resulting in wear and tear on the disc edges and requiring frequent replacement. Rotary drum granulators, on the other hand, utilize automated control to precisely adjust speed and feed rate, eliminating the need for manual oversight. The drum is constructed of wear-resistant stainless steel, resulting in a 40% lower failure rate and over 30% lower maintenance costs, resulting in superior long-term economics.

In summary, the advantages of the rotary drum granulator in terms of production capacity, raw material compatibility, finished product quality, and cost control make it ideally suited to the diverse needs of organic fertilizer production lines, making it an ideal choice for improving efficiency and competitiveness.

The conductor of this orchestra is the highly efficient and reliable NPK fertilizer granulator.

Modern disc granulator designs incorporate innovative concepts: novel and rational structure, significantly reduced weight and height, and flexible, convenient process layout, making them particularly suitable for technical upgrades in existing fertilizer plants. The large-inclination disc body allows flexible adjustment through gaskets, coupled with unique disc treatment technology, ensuring smooth discharge without tearing. Unpowered combination scrapers automatically clean edges, while corner scrapers handle dead spots—these innovative designs result in finished pellets with uniform content and exceptional quality.

More importantly, disc granulation technology demonstrates unique advantages in the NPK fertilizer production process. By precisely controlling disc inclination and rotation speed, producers can easily adjust pellet size to meet the nutritional needs of different crops. This flexibility makes disc granulators the preferred equipment for compound fertilizer manufacturers, especially excelling in producing specialty formula fertilizers.

From raw material proportioning to finished product packaging, disc granulation production lines achieve fully automated control, not only improving production efficiency but also ensuring product quality stability. This is precisely the goal pursued by modern NPK fertilizer production technology: producing the most efficient fertilizers in the most economical way, providing strong support for global food security.

Written by fertilizer production line on September 19th, 2025. Leave a comment

In the granulation stage of organic fertilizer production lines, rotary drum granulators are the preferred equipment for most companies due to their high adaptability to the characteristics of organic fertilizers. Their unique operating principle and performance advantages effectively address key challenges in the granulation process, ensuring product quality and production efficiency.

In terms of granulation adaptability, rotary drum granulators perfectly match the characteristics of organic fertilizer raw materials. Organic fertilizer raw materials, mostly livestock and poultry manure and composted straw, have complex compositions and contain a large amount of fiber. The rotary drum granulator uses the centrifugal force, extrusion force, and friction generated by the rotating drum to granulate loose raw materials without excessive compression, thus preventing the destruction of organic matter and functional microbial activity in the raw materials due to strong compression. The rotary drum granulator also adapts to fluctuations in raw material moisture content (it can handle raw materials with a moisture content of 25%-40%), reducing the tedious pre-treatment process.

The advantages in granulation efficiency and finished product quality are significant. The drum length and diameter of the rotary drum granulator can be flexibly designed to meet production capacity requirements. A single unit can achieve an output of 1-20 tons/hour, meeting the needs of production lines of varying sizes. Its granulation process is gentle and uniform, resulting in highly rounded granules (over 90% roundness). The particle size can be controlled between 2-5mm by adjusting the drum speed and the baffle, meeting standard requirements for organic fertilizer granules. The granules also possess moderate strength, preventing breakage during transportation while slowly disintegrating in the soil, enhancing nutrient release efficiency.

From a cost and environmental perspective, the rotary drum granulator is also competitive. Its simple structure, minimal transmission components, and low failure rate mean ongoing maintenance costs are approximately 30% lower than those of other granulation equipment (such as disc granulators and extrusion granulators). Furthermore, the granulation process does not require the addition of large amounts of binders; granulation is achieved solely through the raw material’s inherent viscosity. This reduces raw material costs while preventing the impact of foreign matter on the purity of the organic fertilizer, aligning with green production principles.

The comprehensive advantages of the rotary drum granulator in adaptability, efficiency, cost and environmental protection make it an ideal choice for the granulation link of the organic fertilizer production line, providing strong support for enterprises to achieve high-quality and high-efficiency production.

Strategies for Protecting Microbial Activity in Bio-Organic Fertilizer Production Lines

Written by fertilizer production line on September 19th, 2025. Leave a comment

The core value of bio-organic fertilizer lies in the activity of its functional microorganisms, and every step in the bio-organic fertilizer production line can affect microbial survival. Effective protection requires scientific management and control throughout the entire process, from raw material processing to finished product packaging.

During the raw material pretreatment stage, the carbon-nitrogen ratio and moisture content must be precisely controlled. Microbial growth depends on an appropriate nutrient ratio. The raw material carbon-nitrogen ratio should be adjusted to between 25:1 and 30:1. Excessively high or low carbon-nitrogen ratios will inhibit microbial metabolism. Moisture content should also be controlled between 50% and 60%, with real-time monitoring using an intelligent moisture meter to prevent excessive moisture from leading to anaerobic fermentation, or excessive moisture from affecting microbial activity.

The fermentation stage is crucial for microbial propagation. When using a compost turning machine for fermentation, the turning frequency must be controlled to ensure that the oxygen content in the fermentation pile remains between 8% and 15% to prevent localized hypoxia that can lead to the death of beneficial bacteria. The fermentation temperature should be strictly controlled between 55°C and 65°C. This range effectively kills pathogens while ensuring the survival of functional bacteria. Precise adjustment can be achieved through temperature sensors linked to the temperature control system. The drying process must avoid high-temperature damage. Traditional high-temperature drying can easily lead to significant microbial inactivation. Low-temperature, negative-pressure drying technology is recommended. Keep the drying temperature between 35°C and 45°C, while maintaining appropriate wind speeds. Reduce moisture to below 15% within 4-6 hours to maximize microbial activity. After drying, the product must be quickly cooled to room temperature to prevent residual heat from affecting the stability of the inoculum.

Product handling and storage are equally important. Before packaging, the product must be screened in a sterile workshop to remove impurities and prevent contamination from external bacteria. Light-proof, breathable inner film packaging bags should be used to prevent direct ultraviolet radiation from damaging microbial cells, and a one-way exhaust valve should be installed to balance the air pressure within the bag. Storage warehouses should be ventilated and dry, with a temperature of 20°C to 25°C and a relative humidity below 60%. Regular microbial counts should be tested to ensure that the product meets the required activity standards before shipment.

Protecting microbial activity throughout the entire bio-organic fertilizer production line requires a combination of process optimization and intelligent management and control. By precisely controlling environmental parameters, bio-organic fertilizers can truly realize their ecological and agricultural value.
