The flat mold granulator uses the center of gravity force of the material for feeding, and the material falls onto the template through the center of gravity force. Does this solve the feeding problem of materials with poor fluidity; The flat mold granulator is an open type machine with good heat dissipation, and the rotational speed is not as fast as the ring mold machine, so it can achieve low-temperature granulation and ensure the survival rate of beneficial bacteria (which is very suitable for fermenting feed).

The flat mold granulator also has a very important point, which is that it is suitable for a wide range of raw materials, because the flat mold granulator uses the principle of extrusion, and the particles produced have a certain strength. No matter what raw materials are, other granulation equipment such as cow and sheep manure with high fiber content, mushroom residue, and rice husks that are added to the fermentation and water absorption cannot form raw materials. The flat mold granulator can be extruded into shape, and the extruded finished products are not scattered during transportation, and are easy to melt when they come into contact with water on the ground.

The granulation advantages of flat mold granulator

1. The complete organic fertilizer production line is not only suitable for organic fertilizers, but also for bio organic fertilizers with added functional bacteria.

Common organic fertilizer granulators include: double roller granulator, rotary drum granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator Machine, ring die granulator, each granulator has its own production characteristics, and the price of granulator varies. Which granulation equipment can be used in npk production line?

There are three main types of compound fertilizer granulators: rotary drum granulator, disc granulator and double roller granulator. What is the difference between these compound fertilizer granulators? What are the advantages and disadvantages of each?

The disc granulator mainly uses the rolling of the disc surface and the granulation of the granules themselves, and is used in conjunction with the upper mixer to achieve a high ball forming rate. The investment cost of granulator equipment is low, and the production capacity is strong, but the dust of open-air granulation is relatively large.

A rotary drum granulator is a forming machine that can shape materials into specific shapes. The main working method is granule wet granulation. With a certain amount of water or steam, the basic fertilizer can fully react after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the extrusion force between the material particles is agglomerated into balls. The investment cost of fertilizer equipment is high, the production capacity is strong, and the dust of drum granulation is relatively small.

The double roller granulator is produced by a non-drying normal temperature process, and it is formed at one time. The equipment has low investment, quick effect and good economic benefit. The complete set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. Various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, and magnetic fertilizers) can be produced.

Organic fertilizer granulator machine is an important machine for the production of organic fertilizer and plays a very important role in the organic fertilizer production industry. Common organic fertilizer granulators on the market include: double roller granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, all kinds of granulators have their own production characteristics, and the prices of granulators vary. Whether it is an organic fertilizer production line or a npk fertilizer production line, what should we pay attention to during the fertilizer granulation process to ensure the smooth and efficient operation of the fertilizer production line?

What should be paid attention to in the process of granular organic fertilizer granulation?

(1) At least 2 powder warehouses to be granulated should be equipped, so that the granulator does not need to stop when changing the formula.

(2) High-efficiency iron removal equipment must be installed before entering the granulator to ensure the granulator.

(3) The organic fertilizer granulator is best placed directly on the cooler, and the crusher is placed under the cooler.

(4) In order to prevent the particles from falling into the bottom of the warehouse and damage the vertical spiral chute in the warehouse.

(5) Finished product packaging should be placed behind the finished product warehouse.

1. Raw material receiving process Select different raw material receiving processes according to the type of raw material received, packaging form and means of transportation. Regardless of the receiving process, raw materials should undergo quality inspection and weight inspection.

2. The receiving of bulk trucks, the raw materials of bulk trucks and tank cars are automatically unloaded into the receiving pit after being weighed by the ground scale. After the raw materials are unloaded into the receiving pit, they are sent to the vertical silo for storage or directly into the bin to be crushed or the batching bin through the horizontal conveyor, bucket elevator, primary cleaning sieve, magnetic separator and automatic scale.

Types of organic fertilizer granulation equipment:

1. Organic fertilizer disc granulator, organic fertilizer stirring tooth granulator (also known as organic fertilizer centrifugal granulator); These two types of granulation equipment rely on the viscosity and moisture of the materials to stick them together. It is required that the materials have a certain moisture content, and the properties of the materials need to be sticky in order to stick together. In summary, high requirements are placed on raw materials (high moisture content and high viscosity), so it is important to choose the right raw materials.

2. Roller granulator; The roller granulator uses two semicircles to press and shape the raw materials together. This type of granulator has a relatively low extrusion strength, and the intersection of semicircles has a clear diamond angle. The raw materials need to have a certain humidity and cannot contain any fiber components. They should be relatively easy to extrude, otherwise they are not easy to form or are fragile after forming.

3. Organic fertilizer extrusion granulator. The organic fertilizer extrusion granulator is a granulator that has been transformed from the original feed pellet machine. There are two types of extrusion granulators: flat mold granulators and ring mold granulators.

The price of organic fertilizer granulator equipment is influenced by many factors, such as equipment scale, brand, production capacity, process parameters, and so on. Generally speaking, the larger the device, the more well-known the brand, and the higher the price. If you want to buy a low-priced organic fertilizer granulator equipment, you can choose some small brands or second-hand equipment, but you need to pay attention to the quality and safety of the equipment. Overall, the price of organic fertilizer granulator equipment is relatively high, and a reasonable budget needs to be planned.

The NPK fertilizer production line is a set of process equipment specifically used for producing NPK compound fertilizers. Its main function is to mix various nutrients such as nitrogen (N), phosphorus (P), and potassium (K) in a certain ratio, and make granular compound fertilizers through specific processes. This production line is of great significance in modern agricultural production, as it can achieve customized production of fertilizers, meet the nutrient requirements of different crops at different growth stages, and improve crop yield and quality.

Firstly, the NPK fertilizer production line has achieved automation and intelligence in fertilizer production. By equipping automatic control systems and advanced production equipment, comprehensive monitoring and precise control of the production process can be achieved, ensuring that each batch of compound fertilizers produced has the same nutritional content and quality. This not only improves production efficiency, but also reduces manual errors, ensuring product consistency and stability.

Secondly, the NPK fertilizer production line can flexibly adjust the fertilizer formula and production process. According to the needs of different crops and the nutritional status of the soil, the ratio of N, P, K and other nutrients can be flexibly adjusted, and an appropriate amount of trace elements and bioactive substances can be added to produce customized fertilizer products that are suitable for specific needs. This flexibility enables the NPK fertilizer production line to meet different agricultural production modes and crop planting needs, providing more refined nutrient management solutions for agricultural production.

In addition, the NPK fertilizer production line also has the characteristics of environmental protection and energy conservation. By adopting closed-loop production processes and efficient equipment, the discharge of wastewater, exhaust gas, and solid waste can be minimized to the greatest extent, reducing environmental pollution and resource consumption. Meanwhile, optimized production processes and equipment design can also reduce energy consumption, improve the energy utilization efficiency of the production process, and meet the requirements of sustainable development.

In summary, the NPK fertilizer production line, as a key process equipment for fertilizer production, plays an important role in improving agricultural production efficiency, improving soil quality, and protecting the ecological environment. With the continuous development of agricultural production and technological progress, the NPK fertilizer production line will continue to play an important role, making greater contributions to agricultural modernization and sustainable development.

NPK fertilizer is a diversified fertilizer that contains various nutrients such as nitrogen (N), phosphorus (P), and potassium (K), and is one of the commonly used fertilizers in agricultural production. The following is the basic production process of the NPK fertilizer production line:

Raw material preparation: The main raw materials for NPK fertilizers include urea, phosphate, ammonium sulfate, ammonium nitrate, potassium chloride, etc. Before starting the production line, it is necessary to prepare various raw materials and ensure that their quality meets production requirements.

Raw material processing: The raw materials undergo processing steps such as weighing, grinding, and mixing to ensure the proportion and uniformity of various raw materials. In this step, the ratio of various raw materials can be adjusted according to the formula requirements to meet the nutritional requirements of different crops.

Wet mixing: Add the processed raw materials to the fertilizer mixer and mix them evenly through wet mixing. During the mixing process, an appropriate amount of water or solution can be added to improve the fluidity and reactivity of the raw materials.

Granulation: Feed the mixed raw materials into a granulator or fertilizer granulator for granulation treatment. The purpose of granulation is to compress the mixed raw materials into granules for easy transportation, storage, and application.

Drying and cooling: The granulated NPK fertilizer needs to be dried and cooled to remove excess moisture and reduce particle temperature, ensuring product quality and stability.

Screening and packaging: After drying and cooling treatment, NPK fertilizer enters the fertilizer screening machine to remove particles that do not meet the specifications and is packaged. Packaging can choose from bagged, loose or large bags, depending on market demand and customer requirements.

Quality inspection and delivery: Finally, quality inspection is carried out on the produced NPK fertilizer, including appearance, component content, particle size, and other indicators. Qualified products will be packaged and shipped to the market.

The entire production process needs to strictly control the operating parameters of each link to ensure the quality and stability of the product. At the same time, attention should also be paid to environmental and safety requirements to ensure that the production process complies with relevant laws, regulations, and standards.

Dry granulation mainly relies on the physical force of the machine to process the material. The huge compaction or compression force provided by this mechanism can make the material particles adhere to each other, the agglomeration is stable, and the appearance and fluidity are good. Granular products are suitable for transportation and storage due to the absence of chemical reactions. Common dry organic fertilizer granulators include double roller granulator and flat film granulators, etc. Low-moisture materials can be dry-granulated at room temperature. Dry granulation technology can be used in many places, such as fertilizer granulation, drug granulation, chemical granulation, livestock feed granulation, food granulation, etc. It is widely used and can be used in npk production line, organic fertilizer production line and so on as needed.

So is the dry granulator a universal granulation method? Of course, dry granulation is not a panacea, it has several disadvantages that you should know.

1. You must pre-prepare the material before pelletizing. The material needs to be fully fermented and chopped. In response to this problem, Heavy Industry Machinery has developed corresponding equipment. You can use our fertilizer composters and shredders for the job, which are also reliable and durable.

2. If the dry granulator is not good enough, you will end up with a lot of powder and dust in the process. But if you are using a dry granulator, this will not be a problem anymore. Our careful design will ensure that the process will not cause air pollution.

3. Since dry granulated granular products are made by extrusion or compression by a machine, they are not perfectly round. You can use a fertilizer granule polisher for this to make the granules look nicer and more spherical.

Cow and sheep manure is a good organic fertilizer raw material, and even if the raw material is good, good methods should be used. Currently, there are many production processes for organic fertilizers in China, and which one is more suitable? At the same time, it is also our goal that we have been pursuing. It is the responsibility of Organic Fertilizer Equipment Manufacturer to enable customers to use appropriate equipment.

In fact, no matter what method we use, the goal is to make the material into circular particles (market demand), and then reduce cost consumption when making circular particles.

According to our survey of fertilizer companies, over 90% of livestock and poultry manure producing organic fertilizers are using disc or drum granulation equipment, with a yield of 50-70%. The moisture content of the material is generally 50-60. This data is very reliable. I believe people who have made fertilizers can basically understand these data. We conducted a special investigation on cow and sheep manure (round particles). Many fertilizer companies use disc granulation or rotation.

These two types of equipment are mainly used for granulation of fertilizers and compound fertilizers, with the basic form of materials being the same. In the early stages, there were basically no professional organic fertilizer manufacturers in China, but many farmers composted themselves, so equipment for organic fertilizer production has gradually begun to be developed in recent years.

At present, the main raw materials for organic fertilizers in China are materials with high organic content such as animal manure, straw, and sugar residue. These raw materials belong to coarse fiber materials. If the decomposition time is not enough, there will be more coarse fibers, which will affect the overall granulation effect of the fertilizer. Disc granulation and drum granulation use the rotation of the equipment itself to bond materials together to form particles, but materials with more coarse fibers cannot form particles through rotation, even if the surface of the particles is rough.

Today, we will mainly discuss the granulation part; The organic fertilizer granulator is mainly designed to manufacture materials with a high amount of coarse fibers. After entering the granulator, the material first enters the feeding system. The feeding system evenly feeds the material into the granulation section. The granulation section is equipped with an alloy blade. The material is polished between the blade and the inner wall to form a master batch. The mother granules enter the plastic surgery area for further adjustment, forming complete granules. After matching the alloy blade, the fiber coarse material can be effectively degraded by 80%. So as to improve the granulation effect!

Blended fertilizer is a compound fertilizer made by mixing different types of fertilizers in a certain proportion, which can meet the needs of different crops for various nutrients. The following are common equipment in mixed fertilizer production lines:

Weighing system: used to accurately weigh various raw materials and ensure accurate mixing ratios. Weighing systems typically include weighing sensors, weighing platforms, and measurement control systems.

Grinding equipment: Grind some larger particles of raw materials for better mixing. Common grinding equipment includes jaw crushers, hammer crushers, etc.

Mixer: a device that mixes various raw materials evenly in a certain proportion. The types of mixers include spiral mixers, vertical mixers, etc.

Conveying equipment: equipment used to transport raw materials to a mixer or granulator, including belt conveyors, screw conveyors, etc.

Granulator: a device that compresses mixed raw materials into granules. The types of granulators include drum granulators, tablet presses, etc.

Drying equipment: Dry the granulated product to remove excess moisture. Common drying equipment includes rotary dryers, fluidized bed dryers, etc.

Cooling equipment: Cool the dried product to lower its temperature. Cooling equipment can be air-cooled cooling machines, water coolers, etc.

Screening equipment: Screen the mixed product to remove particles that do not meet the specifications. Common screening equipment includes drum vibrating screens, rotary vibrating screens, etc.

Packaging equipment: Packaging the produced mixed fertilizer, including automatic packaging machines, weighing packaging machines, etc.

Quality inspection equipment: equipment used for quality inspection of products, including composition analyzers, appearance inspection equipment, etc.

The BB fertilizer mixing and mixing equipment (mixing fertilizer production line) adopts forward and reverse operation, and uses a special inner spiral mechanism and a unique three-dimensional structure to mix and output materials. The equipment is designed with novelty and strong practicality. Its feeding system does not store materials, and the mixing system is evenly mixed. The electronic control system, manual, automatic, and composite settings are all characteristics that similar products do not have. This equipment has the characteristics of low price, small footprint, large output, and uniform mixing.

The dry granulation machine works without involving any liquids, including those binders and humectants such as water, alcohol, etc. Dry granulation mainly relies on the physical force of the machine to process the material. The enormous compaction or compression force provided causes the material particles to adhere to each other. Common organic fertilizer granulators include: roller extrusion granulator, rotary drum granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die pelletizer, Huaqiang Heavy Industry Technology’s dry-laid husk immediately can serve this purpose very well, these are double roller granulator and flat die granulator, they are of high quality, durability and reliability.

1. Fertilizer granulation

Since the dry granulator can improve work efficiency, reduce investment, and improve the nutritional value of granule products to a certain extent, it is widely used in the fertilizer granule manufacturing industry. You can use dry roller press or flat die granulator, organic fertilizer production line, npk production line, etc. at a lower cost.

2. Drug granulation

Dry granulation is important in the manufacture of certain tablets and capsules. It can save a lot of time and effort by making the process much simpler, so it is almost irreplaceable in the pharmaceutical industry. These tablets and capsules can be riboflavin, antibiotics, lactose, etc.

3. chemical granulation

Similar to pharmaceutical granulation, dry granulation is also important in the chemical industry. You can make some solid chemicals into pills or capsules using a twin-roller granulator.

4. Livestock feed pellets

Since the die of the flat die extrusion granulator can be replaced with different holes, you can use it to produce feed pellets of various sizes and shapes by dry granulation. These feeds are suitable for many farm animals such as chickens, ducks, pigs, cattle, sheep, rabbits, fish, etc.
