Granulation Process and Equipment Advantages of the New Type Organic Fertilizer Granulator

fertilizer granulator Aug 22, 2025

The new type organic fertilizer granulator utilizes the mechanical agitation force of high-speed rotation and the resulting air dynamics to continuously mix, granulate, spheroidize, and compact fine powders within the machine, achieving the desired granulation effect.

The resulting granules are spherical with a sphericity ≥0.7, a particle size generally ranging from 0.3 to 3 mm, and a granulation rate ≥80%. Particle size can be adjusted appropriately by adjusting the material mixing ratio and spindle speed. Generally, lower mixing ratios and higher spindle speeds result in smaller particles, and vice versa. This machine is suitable for granulating lightweight, fine powders. The finer the basic particles of the fine powder, the higher the sphericity and the better the particle quality. The particle size before granulation is generally required to be less than 300 mesh.

Typical applications of the new type organic fertilizer granulator include chicken manure, pig manure, cow dung, charcoal, clay, kaolin, and other materials. The new type organic fertilizer granulator boasts uniform granulation and a yield rate exceeding 97%, making it the optimal granulation equipment for organic-inorganic compound fertilizers, organic fertilizers, and bio-organic fertilizers. Due to the coarse fiber properties of the material, rotary granulators have a lower granulation rate, while agitator-type granulators cannot process materials with a nitrogen content exceeding 8% (due to sticking to the wall). This granulator overcomes the shortcomings of both, capable of producing both organic and organic-inorganic compound fertilizers with low energy consumption and high-quality granulation.

The new type organic fertilizer granulator‘s housing is welded from thickened, high-quality carbon steel plates. Ancillary equipment includes pulley assemblies, transmission components, a blower head, and a blower tail. The entire machine is sturdy and durable. The core agitator is precision-cast from a high-chromium alloy and undergoes a special heat treatment, resulting in wear resistance over three times greater than that of ordinary steel. It can withstand the high-frequency friction of fine powders for long periods of time. The main shaft and agitator blades feature a modular design and are fastened with high-strength bolts, enabling easy assembly and simple component replacement, reducing maintenance costs. Adjustable support feet on the bottom of the machine adapt to the flatness of the site, ensuring stable operation and reducing vibration-induced noise and component wear.

The role of uniform feeder in fertilizer production line

In the continuous process of fertilizer production, the uniform feeder is the “nerve center” to ensure the coordinated operation of all links. Whether in compound fertilizer production line or organic fertilizer production line, it can improve the stability of raw material supply by more than 50%, and reduce product quality fluctuations from the source.

The uniform feeder adopts a design combining spiral conveying and frequency conversion speed regulation. The conveying screw is made of wear-resistant alloy material, which can adapt to raw materials with different physical properties such as urea granules, phosphate rock powder, fermented organic fertilizer, etc. The feeding amount can be set with an accuracy of ±2%. It can automatically adjust the conveying speed according to the needs of subsequent crushing, mixing, granulation and other processes to avoid raw material accumulation or feed interruption.

In the compound fertilizer production line, it can accurately convey basic raw materials such as nitrogen, phosphorus, and potassium according to the ratio, so that the nutrient deviation in the mixing link is controlled within 2%, which is much better than 8% of manual feeding. When handling wet organic fertilizer raw materials, its anti-blocking spiral structure combined with the vibration device can effectively avoid material adhesion and blockage, ensuring that the feeding amount per minute is stable at more than 98% of the preset value.

Compared with traditional feeding equipment, the uniform feeder does not require frequent manual adjustment, can reduce 80% of operational intervention, and reduce energy consumption by 30%. The material level sensor equipped with the equipment can monitor the inventory of the silo in real time, automatically start and stop the feeding, and realize unmanned continuous operation.

Whether it is connected to the crushing equipment or the mixer, the uniform feeder can lay a good foundation for the subsequent processes through the stable supply of raw materials. Choosing an appropriate uniform feeder can make the fertilizer production process smoother, the product quality more stable, and demonstrate the core value in large-scale production.

Precautions for Using a Compost Turning Machine

fertilizer granulator Aug 19, 2025

As a core piece of equipment for material fermentation in an organic fertilizer production line, the proper use of a compost turning machine directly impacts production safety and fermentation efficiency. During daily operation, equipment inspection and parameter adjustment must be thoroughly monitored to ensure maximum performance.

A thorough pre-startup inspection is the first line of defense for safe operation. Check the tracks or running wheels for deviation and bolt connections for looseness. In particular, check for breakage or excessive wear on the turning blade assembly to prevent blades from falling off and causing damage to the equipment during operation. Also, clear the fermentation tank of hard objects such as rocks and metal to prevent them from becoming entangled in the turning mechanism and causing it to jam. Electrical system inspection is essential. Ensure cables are intact and grounding is reliable. Install a waterproof cover during rainy weather to prevent electrical leakage.

Parameter adjustment during operation is crucial for ensuring fermentation quality. Dynamically adjust the turning depth and frequency based on the material’s characteristics: High-protein materials like fresh livestock and poultry manure require more frequent turning to ensure ventilation and oxygen supply to prevent anaerobic decay. Crude fiber materials like straw can be turned more deeply to promote even mixing. The turning speed should be matched to the material’s moisture content. If the moisture content is too high, slow the turning speed to reduce clumping. Dry materials can be turned faster to improve efficiency.

Post-downtime maintenance determines the lifespan of the equipment.After each run, clean the blades and trough to prevent caking and compaction, which increases the load at the next start-up. Regularly lubricate bearings, chains, and other transmission components, and promptly replace severely worn parts. When the equipment is idle for extended periods, it should be stored in a dry location, the blades should be coated with anti-rust oil, and the electrical system should be disconnected from the power supply and dust-proofed.

Proper operation of a compost turning machine is not only essential for ensuring production safety, but also a scientific approach to improving fermentation efficiency and reducing operational costs, laying a solid foundation for the resource utilization of organic waste.

How to choose a suitable fertilizer granulator?

fertilizer granulator Aug 16, 2025

In the field of fertilizer production, it is very important to choose the right granulator, which directly affects product quality, production efficiency and corporate benefits. Faced with a wide range of fertilizer granulators, how to choose?

Raw material characteristics are the primary consideration. For processing high-humidity materials such as livestock and poultry manure, the rotary drum granulator can meet the needs; fiber raw materials such as straw have high hardness, and the high-pressure molding technology of the double roller press granulator can ensure the compactness of the particles.

The scale of production needs to be considered. Large production lines have a large daily output demand, and the rotary drum granulator has become the first choice due to its continuous operation ability. It can be adapted to 10,000-ton organic fertilizer projects to meet high-intensity production. Medium-sized enterprises can choose a disc granulator, which can balance efficiency and cost and is suitable for the production of 10-20 tons of compound fertilizer per day. For small workshops or laboratories, the flat die granulator is flexible to operate, occupies a small area, and can easily cope with small batch production.

The requirements for particle quality also affect the choice of granulators. If spherical particles with a high ball formation rate are required, the disc granulator is an ideal choice. The organic fertilizer particles it produces are round and have good commercial properties. For high-strength columnar particles, the double roller press granulator has a good molding effect, high particle hardness, and is not easy to break. The ring die granulator can flexibly switch molds and produce particles of different shapes and sizes to meet diverse needs.

From the perspective of process and economy, in the dry production process, the double roller press granulator does not need to add water, reduces the drying process, and reduces energy consumption. In wet production, the rotary drum granulator and the drying equipment work well together, which is suitable for large-scale continuous production. From the perspective of maintenance cost, the flat die granulator has fewer wearing parts and is easy to repair; although the hydraulic roller granulator has a higher initial investment, it is durable and has a lower long-term use cost.

Considering the above factors comprehensively, select the appropriate one from many models to make fertilizer production more efficient and higher quality.. 

How chicken manure is turned into fertilizer and the equipment used

fertilizer granulator Aug 6, 2025

The large amount of chicken manure produced by chicken farms every day was once a headache for farmers – it piled up and occupied land, the odor disturbed people, and polluted the environment. Today, with the upgrading of environmental protection technology, chicken manure has transformed into high-quality organic fertilizer, and this “gorgeous transformation” is inseparable from the help of professional processing equipment.

The core of chicken manure turning into fertilizer is composting and fermentation. Fresh chicken manure contains a lot of pathogens, insect eggs, and a strong smell of ammonia nitrogen. Direct use will burn the roots of crops and attract pests and diseases. Therefore, the first step is to “disinfect and improve the quality” of chicken manure.

First, send the chicken manure to the dewatering machine to remove excess water. The dehydrated chicken manure cannot be fermented directly, but must be matched with straw and sawdust to adjust the air permeability and make the fermentation more complete.

The mixed materials are sent to the fermentation area, and the turning machine (such as the compost turning machine) is on the scene to turn the materials regularly to ensure sufficient air, so that the upper and lower layers are heated evenly to ensure the fermentation effect.

The fermented materials are crushed and agglomerated by a pulverizer, and the impurities are removed by a drum screener machine. The powdered organic fertilizer obtained can be used directly. If you want to improve storage stability and application convenience, you can perform granulation.

Granulation requires an organic fertilizer granulator to condense the powdered material into uniform particles. Granular fertilizer is not easy to absorb moisture and agglomerate, and it is resistant to loss during transportation and storage. When applied, the amount can be controlled to prevent waste. It can also slowly release fertilizer in the soil, prolong fertilizer effect, and improve crop absorption efficiency.

This system not only solves environmental problems, but also creates profits. Chicken manure organic fertilizer improves soil, improves the quality of fruits and vegetables, and is very popular.

From waste to “hot cakes”, the counterattack of chicken manure is clear. Choose professional equipment to turn chicken manure into treasure, protect green waters and green mountains, and collect gold and silver mountains. This is a wise choice for the circular development of modern agriculture.

Water control of drum granulator during granulation

fertilizer granulator Oct 29, 2020

In chemical processing industry, rotary drum granulator is widely used in organic fertilizer production line and NPK fertilizer production line. In the granulation process of the drum granulator, the coarsening in the pellet is mainly in the form of cladding, so the material circulation volume should be larger, so as to provide a coarser core for the cladding process, and the water injection volume should be smaller, so as to reduce the water absorption of the core.

When pelletizing by bonding or “gathering”, the materials are smaller, because the materials in the drum are mainly composed of fresh materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the space between the fine powder particles to be bonded with each other should be filled with water.

Common problems in the production of organic fertilizer

fertilizer granulator Dec 2, 2019

Fermentation and granulation are the two most critical steps in a complete organic fertilizer production line, so fermentation turners and organic fertilizer granulator machine play an important role in all organic fertilizer plants. Here we will discuss the problems that may be encountered in the production process of these two key links.

There are many types of organic fertilizer fermentation turning equipment, and the models of the same type are also different in size. We can choose according to the production needs. In the current market, the widely used one is trough fermentation, and the representative one is the ordinary trough turning machine, which is suitable for the small-yield organic fertilizer production line and biofertilizer project. When in use, the stacker should be parked in the fermentation open space, and the piled teeth should not be immersed in the raw materials. After the turning teeth are completely rotated, the walking motor can be turned on and the fattening operation can be started slowly. This avoids the large resistance encountered when the turning motor is started, and has some unnecessary consequences; sometimes in order to improve the fermentation tank utilization rate and the high accumulation of fertilizers can also lead to excessive resistance when turning over, with serious consequences.

The importance of organic fertilizer granulator machine in organic fertilizer production line is self-evident. The key to improving product yield and output is organic fertilizer granulation equipment. Depending on the raw materials, we can choose the right granulation machine, but then we have to find ways to use these machines to give them the greatest capacity advantage. Through the principle of granulation, we have learned that the powder raw materials are bonded by water to form spherical particles, so the two indicators of controlling the moisture content and making the moisture content uniform are the key factors for improving the yield. When the moisture content is low, the granulation rate is low, the moisture content is high, and the large particles are large, and the water is not uniform, and the particle size is small and the yield is lower. Therefore, we should constantly explore the optimal moisture content during the production process to ensure high-yield production.

In an organic fertilizer production line, there are many types of equipment such as fermentation turner, organic fertilizer pulverizer, mixing, fertilizer granulator machine, tumble dryer, rotary cooler, drum sieving machine, automatic packaging machine, etc. But here we only list the related topics of the fermentation turner and the fertilizer granulator machine. First, because of the importance of these two devices in the whole set of organic fertilizer equipment, and second, the experience required for the two equipments is relatively high. More, it is necessary to constantly explore and summarize in the future production process to maximize the efficiency of the equipment.

How to Solve Dust Pollution in Organic Fertilizer and NPK Fertilizer Production

fertilizer granulator Nov 28, 2019

Because of the characteristics of materials, a lot of dust will be produced in fertilizer production, which will pollute the environment. In order to avoid this problem, dust removal devices should be set up in the design of organic fertilizer manufacturing process and NPK fertilizer production project to solve the problem of dust emission.

Dust Problem in Organic Fertilizer Production Line

In the organic fertilizer production line, when the moisture content of raw materials is low, they are often crushed and uneven solids. When the raw materials are transported to the equipment, if they are transported in the open air, there is no effective sealing measures, so the dust concentration in the air of the organic fertilizer manufacturing site will be too high. In addition, most small and medium-sized enterprises lack effective treatment means when discharging exhaust gas, which leads to the emission of exhaust gas not up to the standard and dust pollution.

Dust Problem in NPK Fertilizer Production Process

Take NPK fertilizer production project as an example, because the raw material of NPK fertilizer is brittle, it is easy to form small particle dust. When the dust is disturbed by airflow, it is easy to fly. Because of the low water content of NPK fertilizer, the dust is easy to absorb and adhere to the equipment. Therefore, when grading by using the screening device, the dust can easily block the sieve holes of the screen, thereby affecting the grading effect and even damaging the screen. As a result, the screen must be frequently replaced, on the one hand, the production cost is increased, on the one hand, to improve production costs, on the other hand to reduce production efficiency.

To solve the problem of dust pollution in the fertilizer manufacturing process, it is necessary to set up a dust collector room and dust collector equipment in the process of fertilizer production. Tianci Fertilizer Machine Manufacturer have designed a special cyclone dust collector to remove dust from the organic fertilizer manufacturing process. And in the construction of fertilizer plant, dust collector room is more suitable for large NPK fertilizer production line, we can help customers build dust collector room.

Instructions for making chicken manure organic fertilizer

fertilizer granulator Nov 26, 2019

The feces in the farm is a major problem that plagues the farm to solve the environmental pollution at this stage, therefore, we can only solve the pollution angle, to achieve the purpose of waste utilization, through decades of continuous exploration and research, Zhengzhou Tianci Heavy Industries summed up the most effective method of producing organic fertilizer production line from animal waste fermentation, this will not only convert waste into usable energy but also solve the pollution caused by aquaculture.

Fermentation is mainly in the ground stacking or fermentation tank, that is, chicken manure stacked in the fermentation tank, the best at the same time to add the appropriate amount of fermentation bacteria, the use of a compost turning machine stirring evenly, usually fermentation time of 12-15 days.

After deep fermentation of chicken manure, it’s dried and crushed. The chicken manure after crushed can be directly applied, but is only called the traditional farm fertilizer, cannot be called commodity organic fertilizer.

However, if you want to make commercialized organic fertilizer, i.e. implement the NY525-2011 standard. According to this standard, the total content of NPK must be greater than or equal to 5%, organic matter must be greater than or equal to 78%, water is less than or equal to 30%, and the PH value is 5.5-8.0. Of course, there are other requirements, such as heavy metal content cannot exceed the standard, tick egg mortality and E. coli value, etc. need to meet the standard. Only meet the above requirements are qualified organic fertilizer. In terms of appearance, commodity organic fertilizers are divided into powder and particles. If you want to produce grain-forming commodity organic fertilizer, but also need to use fertilizer granulator for granulation, organic fertilizer granulation production equipment generally uses a disc granulator machine. Others have rotary drum granulator machine, etc.

Our company is specialized in the organic fertilizer production line, the production of fertilizer equipment are: compost turning machine, crusher machine, blender, fertilizer granulator machine, etc., welcome to inquiry.
