What is the production process of an organic fertilizer production line?

fertilizer granulator Aug 18, 2025

In terms of equipment, an organic fertilizer production line requires a fermentation compost turner, fertilizer crusher, fertilizer mixer, fertilizer granulator, fertilizer dryer, fertilizer cooler, fertilizer screening machine, fertilizer packaging machine, fertilizer conveyor, and fertilizer coating machine.

The raw materials used in organic fertilizer production vary widely, including livestock and poultry manure, municipal sewage sludge, and animal and plant residues. These raw materials are rich in organic matter, nitrogen, phosphorus, potassium, and other nutrients, providing essential nutrients for crop growth and are available at low prices.

How an organic fertilizer production line works:

Organic fertilizer processing primarily involves collecting, crushing, and mixing the raw materials. The raw materials are then mixed according to the desired formula, and the moisture content and carbon-nitrogen ratio are adjusted before the fermentation process begins.

Fermentation compost turning machines: Assist in turning the compost during the fermentation process, provide sufficient oxygen, and control the temperature to ensure uniform and thorough fermentation.

Fertilizer mixers: If the size and state of the fermented material are inconsistent, a semi-wet material grinder can be used for fine grinding.

Fertilizer Granulator: The crushed material is processed into uniformly sized organic fertilizer granules by the organic fertilizer granulator.

Fertilizer Cooler: After granulation, the organic fertilizer still contains approximately 30% moisture. To increase its strength, the granules need to be cooled for later storage and transportation.

Fertilizer Screening Machine: After granulation, a small number of unqualified granules, some too large and some too small, will be produced. The fertilizer screening machine is used to separate these granules. Oversized granules are returned to the fertilizer crusher, while undersized granules are returned to the fertilizer granulator for regranulation. Qualified granules are then sent to the automatic packaging machine.

Fertilizer Packaging Machine: The finished organic fertilizer granules are packaged by the automatic packaging machine, completing the entire process.

It should be noted that the above configuration is for a typical organic fertilizer production line and may not be suitable for all situations. In actual production applications, different manufacturers may have different requirements regarding site and raw materials, and adjustments may be required based on actual needs.  

The secrets of organic fertilizer production line and bio organic fertilizer production line

fertilizer granulator Aug 16, 2025

In agricultural production, the quality of fertilizer directly affects the growth and harvest of crops. Today, let’s take a deep look at the differences between organic fertilizer production line and bio organic fertilizer production line to help you make a better choice.

Organic fertilizer production line mainly uses animal and plant residues, such as livestock and poultry manure, crop straw, etc. as raw materials. After collection, pretreatment is first carried out, such as crushing and mixing, to make the raw materials uniform in texture. Then enter the key fermentation and decomposition link, using natural microorganisms to decompose and transform organic raw materials under suitable temperature, humidity and ventilation conditions. This process often takes several months to make organic matter reach a stable state and finally make organic fertilizer.

Bio organic fertilizer production line goes a step further on this basis. After the raw materials are also collected, pretreated and conventionally fermented and decomposed, wait for the material temperature to drop to a suitable range (usually not more than 40℃), and evenly mix in specific microbial agents, such as Bacillus, yeast, etc. These microorganisms play an important role in the follow-up, and can decompose nutrients such as insoluble phosphorus and potassium in the soil and convert them into plant-absorbable forms. However, since microorganisms are sensitive to the environment, the subsequent storage and transportation conditions must be strictly controlled to prevent inactivation.

From the production process point of view, the bio-organic fertilizer production line adds the addition of microbial agents. It seems simple, but it has higher requirements for equipment and environment, and the production process is more complicated.

In terms of product effect, organic fertilizer can improve soil structure, slowly release nutrients, and provide long-term nutrition for plants; bio-organic fertilizer not only has these functions, but also can prevent and inhibit pests and diseases, enhance plant resistance, reduce the use of pesticides, and improve the quality and safety of agricultural products.

Whether you want to invest in organic fertilizer production or focus on bio-organic fertilizer processing, choosing our equipment can escort your production, help you produce high-quality fertilizers, and seize the opportunity in the field of agricultural planting.

Drum Granulator: A Quartet of Process Innovations

fertilizer granulator Aug 16, 2025

In modern fertilizer production, rotary drum granulators are redefining granulation standards with four innovative features. How do these carefully designed functions work together to create energy-efficient production miracles?

Drum granulators are commonly used in organic fertilizer production because they efficiently form moist organic material into uniform granules through a rotating drum mechanism. They are a key component in organic fertilizer production equipment, which also includes mixers, crushers, dryers, and screening equipment. While granulators specialize in granulation, complete production lines (organic fertilizer production equipment) integrate multiple steps to transform raw organic waste into high-quality fertilizer.

“From steam conditioning to self-cleaning design, each innovation makes granulation more precise and efficient”

Intelligent Steam Conditioning System

The revolutionary steam injection technology acts like precise “thermal therapy” for materials. Steam penetrates the material bed, raising temperature while dissolving salts to form a liquid phase film, enabling ideal liquid phase conditions at low moisture content. This innovation reduces drying evaporation water by 40% and energy consumption by 35%.

⚗️Controlled Ammoniation System

Ammonia gas can be precisely introduced into the drum as needed to promote chemical reactions. This controlled ammoniation technology acts like a “chemical catalyst”, not only adjusting product pH but also improving granule structure, enhancing slow-release performance by 30%.

Self-Cleaning Liner Design

The special rubber or polypropylene liners embedded in the drum wall, combined with cleverly designed air holes, form an intelligent self-cleaning system. When liners rotate to the top, they sag under their own weight, causing adhered materials to fall off automatically. This “self-renewal” mechanism solves traditional granulator sticking problems, reducing maintenance costs by 60%.

Extensive Material Adaptability:

Low-solubility Materials High-solubility Materials Organic Matter Trace Elements

Whether it’s poorly soluble potassium sulfate and potassium chloride, highly soluble urea and ammonium nitrate, or various organic materials and trace elements, this system handles all perfectly. This “non-picky” characteristic reduces formula changeover time by 80%.

Four innovations, four advantages – the drum granulator is driving fertilizer production toward greater efficiency and intelligence with its technological charm.

Reasonable ratio of raw materials is the basis to improve the ball formation rate

fertilizer granulator Jan 5, 2021

Single chemical fertilizer can not meet the needs of various nutrients of plants. NPK fertilizer production line mixes and granulates different nutrients to improve fertilizer efficiency. So how to improve the pelletizing rate of fertilizer?

1. Reasonable match of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: about 30% – 40% of the raw materials with 100-60 mesh, about 35% of the raw materials with 60 mesh to 1.00mm diameter, and about 25% – 30% of the small particles with 1.00-2.00mm diameter. The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the proportion of high fineness materials is too high, and it is easy to cause the bad problems such as too large particles, irregular particles and material wall sticking due to the good viscosity.

2. The reasonable collocation of cohesive material and dispersive material. In the production process formula, the proportion of viscous raw materials is high, the organic fertilizer granulator is easy to form balls, the proportion of dispersive raw materials is high, and there are more fine powders. In the conventional formula, the proportion of low concentration compound fertilizer viscosity raw material is 45% – 50%, and the proportion of high concentration compound fertilizer viscosity raw material is 35% – 40%. At the same time, it should be combined with material fineness. With bad matching, there will be no fine powder, no particles, particles are not round, easy to get big balls and other problems in the production process.

3. The chemical reaction between materials should be considered when formulating. After the formulation of some materials, free water will be precipitated during the production process, which will cause the liquid phase of the material to exceed the standard and cannot be produced normally. After matching, some raw materials will greatly reduce the critical relative humidity of the mixture. During the process of organic fertilizer production equipment, due to the large amount of moisture absorption Unable to produce normally. Therefore, the chemical reaction between the materials must be considered when formulating to achieve a reasonable match between the materials.

4. Comprehensive water content of the material after mixing. The water content of the raw materials directly affects the pelletizing effect of the disc granulator machine. Some materials are stirred into mud without steam and water in the production, resulting in the failure of normal production. Therefore, keeping a low water content of the material is conducive to the addition of steam in the granulation, to the improvement of the temperature and viscosity of the material, so as to improve the compatibility between the materials and the balling rate.

How to prevent organic fertilizer facilities from rusting in rain

fertilizer granulator Nov 19, 2020

Fertilizer machine is valuable. After we buy organic fertilizer equipment, we should also pay attention to maintenance in daily use. Rust is a problem often encountered by the organic fertilizer production equipment, especially in rainy days. Although the machine is not exposed to rain, it will still find rust when it is used later. What should be done in this case? Let’s explain how to prevent the fertilizer facilities from rusting in rainy days.

There is more rain in autumn. In rainy season, people will store the organic fertilizer equipment in the designated place as usual, but when it is reused after rainy day, it will be found that the organic fertilizer equipment is rusty, some mechanical parts are aging, and some parts are wet. Therefore, in view of these problems, how to keep the organic fertilizer plant in rainy days is very important.

1. Rust proof iron work. At present, the use of organic fertilizer production facilities and most of the accessories are made of iron. They are not well preserved, easy to rust and shorten the service life. The machine should be painted with antirust paint and stored in a ventilated and dry place. It is better to set up canopy for compost turning machine.

2. Anti aging of rubber parts. When the rubber parts of the organic fertilizer production equipment are damped or stained with oil, they are easy to age and crack, thus shortening their service life.

3. Protect the motor from moisture. The motor of the organic fertilizer granulator is not used for a long time, and it should be placed in a ventilated, dry and clean warehouse. If the motor is placed in the fertilizer wetland or the place easy to be wet by rain, the motor will be damped and the insulation performance will be reduced, which has caused short circuit, electric leakage, ironing and even burning coil.

The above is a simple way to prevent the equipment from rusting. As for NPK fertilizer production line and other heavy machinery, we should pay more attention to the maintenance and do a good job in the daily maintenance of the equipment, which is conducive to prolonging the service life of the fertilizer equipment and reducing the number of failures of the organic fertilizer equipment in use.

How to deal with livestock manure on large farms

fertilizer granulator Jun 19, 2020

For farms, the biggest environmental problem is that there is no place to stack a lot of feces. If these excrement are not managed scientifically, it will harm human and animal health and pollute the surrounding environment. The aquaculture industry needs to be carried out, and environmental protection treatment also needs to be paid attention to, so what are the methods of manure treatment in the farm? How to deal with feces to achieve harmless requirements? Is there a technology that saves money and is simple? The most effective way is to use organic fertilizer production equipment to process manure into fertilizer products.

How to make waste into organic fertilizer is an urgent need for farmers to understand. What kind of process is simple and can solve the problem to the greatest extent? If the feces of the farm are treated innocuously, several aspects should be paid attention to:

1. Collect and stack dry manure. The stacking place must be rainproof and impermeable, and be cleaned and transported regularly. The ground of the stacking place shall be hardened completely, and the leaching solution collection ditch shall be built around, and the collection ditch shall be connected with the biogas digester. The volume of the stacking area depends on the scale of the farm. Taking the pig manure treatment method as an example, the required volume for every 10 pigs is usually 1 cubic meter. When the water content of stored pig manure is too large, it needs to use solid-liquid separation equipment for dehydration treatment, which can reduce air and water pollution.

2. Anaerobic fermentation is carried out for faeces, urine and sewage. The biogas produced can meet the requirements of life and part of production energy in the field and reduce the production cost. The size of the biogas digester depends on the scale of the farm. The required biogas digester volume for every 10 pigs is about 2 cubic meters.

3. Manure can be directly processed into organic fertilizer or fermented into biogas residue and then processed into organic fertilizer. Due to the large investment in biogas system, this method is suitable for large-scale farms. Manure production of organic fertilizer can not only solve the problem of a large number of manure pollution, but also turn waste into treasure to produce a large number of green ecological fertilizer. Using fertilizer granulator to process manure compost can also increase the price of fertilizer and further create economic and social benefits for enterprises.

Through the multi-level recycling mode, the farm not only solves the problem of excrement, but also obtains additional income. We are a professional fertilizer machine manufacturer, providing fertilizer production line and organic fertilizer equipment.

How to Use Organic Fertilizer Equipment to Produce Tomatoes Fertilizer

fertilizer granulator Jun 17, 2020

The application of chemical fertilizers in agricultural production can increase the yield of crops, but it will cause soil compaction, the quality of agricultural products will decline, and the nitrate content in fruits and vegetables will be too high. Bio-organic fertilizers are increasingly used in agricultural production. The organic fertilizer production equipment can combine organic matter and inorganic fertilizer to make fertilizer suitable for tomato development.

Organic fertilizer production line to produce special tomato fertilizer

Organic-inorganic fertilizer production line mix organic matter and inorganic fertilizer in proportion to prepare fertilizer. According to the formula blending two kinds of fertilizers, the automatic batching system mixes the raw materials strictly according to the parameters, so that the raw materials are suitable for the growth of tomatoes, and automatic batching system can mix organic fertilizers and inorganic fertilizers according to the setting of 3:7. Mixed uniform particles are agglomerated and granulated by organic fertilizer granulator machine. Granular organic fertilizer keeps good characteristics of fertilizer. Fertilizer granulatormachine is suitable for mixing and granulating of various materials. The granules made by the machine have high strength and are not easy to break. After a series of treatments, such as drying and screening, fertilizer granules are special organic fertilizer for tomatoes.

Advantages of products of organic fertilizer production equipment

1. The combination of bio-organic fertilizer and inorganic fertilizer promotes tomato growth, nutrient uptake by root system and nutrient utilization efficiency. When bio-organic fertilizer is applied alone, the nutrient content of the fertilizer used is lower than that of inorganic fertilizer, which will have a certain impact on the yield.

2 The application of bio-organic fertilizer can improve the quality and palatability of tomatoes, reduce the nitrate content in tomatoes, and increase the content of vitamin C and reducing sugar.

3. The application of bio-organic fertilizer in tomato production can reduce the occurrence of tomato mosaic virus disease and the effect of disease on Yield and quality.

Sheep manure organic fertilizer production line

fertilizer granulator Dec 9, 2019

Sheep manure organic fertilizer production line:
First. Mix the sheep manure with the crop straw. The amount of the sheep manure depends on how much the water content of the sheep manure is determined. According to the fermentation process, the water content is required to be within 45%, that is, the material is kneaded into a mass, and the water can be seen. Will not drip down, loosen the group will spread out. Then, the cornmeal and the required strains are added. The reason for the cornmeal is that the sugar content can be increased to promote the rapid fermentation of the strain.

Second, the configured materials are added to the material mixer for mixing, and the mixing is required to be uniform and transparent, and no raw blocks are left.

Third, the mixed materials are piled in a fermentation tank or grooves with a width of 2 to 6 meters and a height of 1.0 meters to 1.5 meters, and are repeatedly turned over and thrown every other day using a compost turning machine.

Four, under normal circumstances, in the fermentation tank, the temperature will rise after stacking for 2 days, and it will be odorless after 2 days. After 3 days, it will become fluffy and loose. After 2 days, compost will emit fragrance, 15 days, it can be fat.
1. In the fermentation tank for 2 days, the temperature will rise to 60 ° C to 80 ° C, which will kill bacteria and remove insects.
2. On the fourth day in the fermentation tank, the odor is eliminated; then on the seventh day, the material in the tank will become loose, dry and covered with white hyphae.
3, fermented in the pool to the ninth day, the nine will emit a fragrance, basically similar to the koji.
4. Fermentation to the tenth day in the tank, the material will be fermented and cooked, and sufficient.
5. On behalf of the end of the fermentation stage, the material can be removed to the next step with a forklift or the like.

Five. The material moved by the forklift to the pulverizing process is pulverized by a semi-wet and high-humidity material pulverizer, and then mixed by a mixer machine, transported to fertilizer granulator machine by a conveyor, and granulated into granules, It is sent to the dryer by the belt conveyor, dried and dried, and then cooled into the cooler. Then the conveyor is sent to the screening machine for screening. The required particles of more than 95% will enter the next process, and about 5%. The granules are transported to the pulverizer for re-pulverization and granulation, and the granules that meet the standards are fed into the coating machine for coating. The coating can maintain the nutrients, and after coating, it is packaged by an automatic packaging machine. In this way, the sheep manure organic fertilizer is processed and packaged and can be sold in the warehouse.All the organic fertilizer production line is done.

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 Make Organic Fertilizer by Feces Composting

fertilizer granulator Nov 19, 2019

Fecal composting organic fertilizer manufacturing process is to adjust the carbon-nitrogen ratio in the manure of the livestock and poultry by turning machine, manually controlling the conditions of water, temperature, pH and the like, and treating the manure of the livestock and poultry by the fermentation of the microorganisms to produce organic fertilizer.

I. Major organic fertilizer production equipmentfor composting

The composting process requires a large number of organic fertilizer processing equipment.

(1). Pre-treatment equipment: mainly include stockyard, unloading platform, feeding door, loading machinery, transport machinery and so on.

(2). Composting equipment: mainly trough compost turning machine, windrow turner machine, fermentation tank.

(3). Fertilizer granulator machine : mainly drum granulator, disc granulator, flat-die extrusion pelleting machine, organic fertilizer granulator, ring-die pelleting machine.

(4). Screening and packaging equipment: mainly drum screener, fertilizer packing machine.

II. Main Technical Parameters of composting

(1). C/N ratio: C/N balance of compost mixture is the key factor for microorganisms to achieve better biological activity. The C/N ratio of compost mixture should be kept at 25-35:1.

(2). Humidity: Aerobic composting should generally be maintained at 40-70%.

(3). Acidity and alkalinity: Acidity and alkalinity vary with the types of compost mixtures and different stages of composting process. Normally, they need not be regulated. If they need to be regulated, they can be regulated by adding alkaline or acidic substances to the mixture before the beginning of composting degradation.

(4). Other design parameters: Rectangular fermentation stacking composting mode, the windrow turner should be used regularly to turn the pile, so that the temperature is kept below 75℃, and the turning frequency is 2-10 days/time. The width and depth of rectangular stacks are limited only by the overturning equipment. The stacks are generally 1.2-1.8 meters deep and 1.8-3 meters wide. The height of the compost is usually 2.5-4.5 meters, and the width is usually twice the depth. Fermentation tank composting, need to build fermentation tank, fermentation tank length is unlimited.

III. Matters needing attention in composting

(1). Composting time: Composting time varies with C/N ratio, humidity, weather conditions, type of composting operation and management, waste and additives. The composting time of well-managed strip-cutting fermentation compost in summer is generally 14-30 days.

(2). Temperature: We should pay attention to the monitoring of composting temperature. The composting temperature should exceed 55℃, so as to be conducive to microbial fermentation and kill pathogens.

(3). Humidity: Pay attention to monitoring the humidity of compost mixture periodically. Excessive or low humidity will reduce or stop the composting speed.

(4). Odor: Odor is a good indicator of composting operation stage. Decay odor may mean that compost is changed from aerobic to anaerobic.
