The humic acid in earthworm manure is different from that in general organic fertilizers because earthworms regularly digest and mix many organic nutrients to transform them into water-soluble substances, which are easily absorbed by plants. Planting crops with earthworm manure not only has the effects of drought resistance and fertilizer retention, promoting roots and seedlings, and not reducing production, but also significantly improves the quality of crops and restores their natural flavor. It can also be used as an additive for poultry and livestock feed, making it convenient, clean, and safe to use.

The complete set of organic fertilizer production line for processing earthworm manure is a complete set of production equipment that uses earthworm manure as raw material and undergoes a series of processing treatments to produce earthworm manure fertilizer. Due to its unique characteristics, it has now been widely used in major aquaculture farms in China. It is reported that the complete set of earthworm manure processing organic fertilizer equipment production line mainly has the following advantages: the first point is that earthworm manure organic fertilizer does not contain any chemical components.The second point is that the main substance in earthworm manure organic fertilizer is organic matter, which increases the organic matter content in the soil. The third point is that earthworm manure organic fertilizer can also promote the proliferation of microorganisms in the soil, especially many beneficial microorganisms such as nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc.

The organic fertilizer production line equipment consists of several parts: fermentation system, drying system, deodorization and dust removal system, organic fertilizer crusher, ingredient system, mixing system, organic fertilizer granulator, and finished product packaging machine. Although the process structure is similar, the configured organic fertilizer equipment is not fixed. The manufacturer will mainly provide customers with equipment construction and equipment selection plans that meet their own conditions for the annual production of 10000 tons of organic fertilizer production line based on user material characteristics, on-site operating conditions, specific production requirements, automation level, and investment budget.

Organic fertilizer granulator includes: disc granulator, new organic fertilizer granulator machine, drum granulator, roller extrusion granulator, etc. The most commonly used granulation equipment is the above. In the production of organic fertilizer, the selection of the granulator is usually determined according to a variety of factors, such as raw materials, output, and price.
The new organic fertilizer granulator machine is a granulating equipment specialized in the production of organic fertilizer. It is also called an internal stirring tooth granulator. It is suitable for granulating materials with relatively large fibers. The shape of the finished product is oblate and needs to be processed by a rounding machine. It can be processed into a circle.

Both the drum granulator and the disc granulator belong to the agglomeration method.Compared with the disc granulator, the drum granulator relies on the temperature of the high granulation to increase the amount of liquid in the basic material, and promote the material to be more Balls are formed under low water content, which has the advantages of easy drying, energy saving and consumption reduction. But when the process conditions are not well controlled, the return material is high.
The roller extrusion granulator is a room temperature granulation equipment. It does not produce a large amount of dust and smoke during work. It has a wide range of applicable materials and can granulate materials that cannot be processed by other granulators. The high rate, the disadvantage is that the output is not very high, usually it is necessary to configure several pairs of roll extrusion granulators to work at the same time. 

The cow manure composting and fermentation organic fertilizer tipping machine and the tank type tipping machine are currently the most widely used fermentation equipment. The tipping and tipping equipment includes a walking fermentation tank body, a walking track, a moving device, a tipping and tipping department, and a turning device.

The cow manure composting and fermentation organic fertilizer tipping machine is mainly used in the working situation where the width of the tank is not more than 5 meters and the depth of flipping is not more than 1 meter. The bearing seat of the flipping device is fixedly connected to the flipping frame, and two main shafts are fixedly connected to the bearing seat. Each main shaft is welded with several flipping shafts arranged at a certain interval and staggered angle, and each flipping shaft is welded with a flipping plate. The tipping device is connected to the walking device through a pin shaft. The bearing seat of the walking device is fixedly connected to the walking frame, and two connecting shafts I equipped with walking wheels are fixedly connected to the bearing seat. One end of each connecting shaft I is connected to one end of the connecting shaft II through a coupling. The two output shafts of the reducer II are respectively connected to the other end of the two connecting shafts II through a coupling. The electric hoist of the lifting device is fixedly connected to the walking frame, with one end of the steel wire rope wrapped around the electric hoist and the other end fixed to the overturning frame.

Using a composting machine to ferment cow manure and other raw materials – crushing the fermented organic fertilizer – stirring the raw materials evenly with a mixer – granulating with a granulator – evaporating the moisture in the particles with a dryer – cooling the particles with a cooling machine to quickly reduce the temperature – screening the unqualified particles and re crushing them for granulation – coating the qualified particles – quantitatively bagging the final organic fertilizer products. The complete set of granular organic fertilizer production line has more equipment than simple configuration, such as a stacker, dryer, cooler, and coating machine. However, the selling price of finished products is much higher than that of simple production, and the market competition is relatively strong.

Pig manure is a commonly used organic fertilizer raw material, which is fermented to become a high-quality organic fertilizer with a wide range of uses. However, using natural fermentation pig manure to make organic fertilizer takes 1-3 months, which makes friends who want to make their own organic fertilizer stay away. For this issue, organic fertilizer flipping and throwing machine equipment has emerged. Using the flipping and throwing machine to produce organic fertilizer can shorten the time to less than one month. So how can we use the organic fertilizer flipping and throwing machine to produce pig manure organic fertilizer?

Method for producing pig manure organic fertilizer using an organic fertilizer flipper:

1. Preparation and adding bacteria: Prepare the feces that need to be fermented, preferably fresh pig feces (the fermentation effect of fresh feces is better than that of old feces), such as adding 0.25 kilograms of pig manure fermentation agent to about 1 ton of fresh pig feces. First, mix the pig manure starter with rice bran (or corn flour, wheat bran) in a ratio of 1:5~10 for standby.

2. Pig manure pile construction: Build a pile of prepared pig manure while spreading bacteria. The height and volume of the pile should not be too short or too small. Requirements: the pile height should be 1.5 to 2 meters, the width should be 2 meters, and the length should be unlimited.

3. Adjust moisture. The moisture content of fermented pig manure should be controlled between 40-65%. Moisture judgment: Grasp a handful of pig manure tightly, see watermarks on the fingertips but do not drip, and it is advisable to scatter it upon landing. Less water leads to slow fermentation, and more water leads to poor ventilation, which can also cause “spoilage bacteria” to work and produce a foul odor. Therefore, it is important to control the moisture content.

4. Starting temperature. The starting temperature should be above 15 ℃, which is suitable for operation in all seasons and not affected by the season. In winter, it is recommended to ferment indoors or in a greenhouse, and the fermentation temperature should be controlled below 70-75 ℃.

5. Mix well and ventilate. Pig manure fermentation agents require aerobic fermentation, therefore, during the operation process, oxygen supply measures should be increased to achieve mixing, flipping, and aeration. Otherwise, it will cause anaerobic fermentation and produce a foul odor, which will affect the fertilizer effect.

6. Fermentation completed. Generally, after 48 hours of pig manure accumulation, the temperature rises to 50-60 ℃, and can reach over 65 ℃ on the third day. At this high temperature, the pile needs to be turned over once. Generally, there will be two times of high temperatures above 65 ℃ during the fermentation process. Turning over the pile twice can complete the fermentation, and it can be completed within a normal week. The material appears black brown and the temperature begins to drop to room temperature, indicating the completion of fermentation.

There are four types of granulation in the NPK fertilizer production line on the market: 1. Disc granulation is suitable for small output devices, and generally does not exceed 50,000 tons/year. It is the primary stage of drum npk fertilizer granulation. 2. The drum npk fertilizer granulator is widely used, and the pellet size is also better, including drum ammoniation granulation and drum agglomeration granulation. Among them, the ammoniation is divided into one-step ammoniation and two-step ammonia The two-step amination method includes the amination reaction in the conversion tank and the amination reaction in the granulator. 3. Shotcrete granulation is the predecessor of ammoniated granulation and the technology is relatively mature. 4. High-tower granulation means that the raw materials are sprayed through the high-tower in a molten state at a high temperature. The pellets are formed into pellets during the falling process. The pellets are relatively strong and smooth. The pellets generally have a small hole, dissolve faster, and have obvious fertilizer efficiency. The market prospect is better. 

The rotary drum npk fertilizer granulator sprays water vapor at a constant pressure on the material, so that the material obtains moisture while being applied with a constant pressure to form small particles, which are formed into particles of a fixed size during the process of rotation. The humid granulation environment allows the drum granulator to produce a compound with a high content of nitrogen, phosphorus and potassium, but the cost is relatively low.
Advantages of the drum npk fertilizer granulator: By increasing the granulation temperature, the liquid content in the basic material is increased, which promotes the material to form a ball at a lower water content, and has the advantages of easy drying, energy saving, and consumption reduction.
Disadvantages of drum npk fertilizer granulator: When the process conditions are not well controlled, the return material is higher than that of the disc granulator.

Cow manure is fermented and processed into organic fertilizer, which not only achieves waste reuse but also reduces the production investment cost of farmers. High degree of harmlessness, improved soil, beneficial for absorption, slow and efficient, increased production and income, fertilized soil fertility, balanced nutrition, low production cost of biological composite bacterial agents, can improve soil, improve crop product quality, and increase crop yield. It is commonly used for various economic crops and food crops such as fruits, vegetables, fruit trees, grass, tea, etc.

Process steps for producing granular organic fertilizer from cow manure

Step 1: Fermentation and Maturation

Collect cow manure and urine, mix them with straw, hay, and other ingredients to control the moisture content by about 65%. Stack the materials into strips with a width of no less than 10 meters and a width of 2-5 meters. Sprinkle 1KG of aerobic fermentation bacteria with 2-3 cubic meters. Mix thoroughly with a wheeled composting machine and let them ferment. After fermentation, use a composting machine to cool the materials.

Step 2: Material crushing

Crush the organic raw materials of fermented and decomposed cow manure. Organic fertilizer wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. Utilizing high-speed rotating chains to crush fibers with good particle size.

Step 3: Mixing and stirring

Add trace elements, excipients, humic acid, clay, etc. for mixing and stirring. Using a vertical mixer, the mixing speed is fast and the uniformity is good. It can mix viscous materials with a liquid content of 30%. During operation, there are two opposite rotating blades and rotors stirred in the middle. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Forming and granulation

The material is granulated using a disc granulator, an organic fertilizer stirring tooth granulator, or a new type of stirring tooth rotating strand three combination granulator.

Step 5: Drum drying

The organic fertilizer dryer further removes moisture from the granulated particles to meet the standard requirements for organic fertilizer moisture content.

Step 6: Drum cooling

Cooling the dried granular material with a cooling machine helps to preserve the quality of the particles.

Step 7: Screening and return system

Due to the differences in particle size of the granulated material output from the granulation and forming system, screening and grading are required. The selected drum type screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

Step 8: Particle coating equipment

The coating machine is composed of a screw conveyor, a mixing tank, an oil pump, a main engine, etc., and is used for powder or liquid coating technology. It can effectively prevent the caking of fertilizers, and the host is lined with polypropylene or acid resistant stainless steel.

Step 9: Packaging Equipment

Granular materials are packaged and transported through conveying equipment into the finished product warehouse. Granular materials are quantitatively weighed and packaged through automatic packaging scales.

The disc granulator is suitable for granulating round fertilizer granules of compound fertilizer or organic fertilizer, which is convenient for transportation and storage. In order to produce fertilizer granules with balanced nutrition, a proper granulator is your ideal choice. We are a professional fertilizer factory and will provide you with practical guidance on fertilizer granulation.

The disc granulator takes the motor as the power to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it will roll down by itself, just like a snowball. It is suitable for non viscous powder materials.
Some customers have seen the process of organic fertilizer processing and want to process feed pellets, but they don’t know whether the disc pelletizer is suitable. The answer is: yes. Because the characteristics of feed ingredients and organic fertilizer ingredients are basically similar, this equipment is wet granulation, which has a wide range of applicable raw materials. When we use the disc granulator for processing, sometimes the particles are larger and sometimes smaller. The way to solve this problem is to adjust the moisture of the material.
When purchasing an organic fertilizer granulator machine, customers must choose a manufacturer with a certain technical strength and perfect after-sales service. Nowadays, there are many companies producing organic fertilizer granulators in the country, and some companies have no technology at all, and they are completely imitated by other manufacturers. During production, the quality of the organic fertilizer granulator machine manufactured is not up to standard, and some of them cannot be used normally.

How should farmers configure suitable organic fertilizer production equipment based on their breeding scale? Firstly, the livestock and poultry manure generated by the scale of breeding needs to be sufficient for the normal fermentation production of the organic fertilizer production line. The production capacity of the organic fertilizer production line is very large, producing 2-20 tons of organic fertilizer per hour.

If the production scale of livestock farms is too small and poultry manure is used as the raw material for organic fertilizer production, the raw material for organic fertilizer will be insufficient. Joining the introduction of an organic fertilizer production line would result in most of the equipment being in a stagnant state, which is clearly not cost-effective. We all know that the water content of poultry and livestock manure is relatively high, and the water content requirement of organic fertilizer cannot be higher than 30%. Therefore, the amount of poultry and livestock manure required to produce one ton of organic fertilizer should be higher than one ton. If the scale is insufficient, simple composting fermentation can be directly returned to the field. If the labor of composting is too strong, organic fertilizer flipping machines can be used.

The whole machine of the chicken manure organic fertilizer tipping machine adopts high-strength chain transmission, hydraulic control lifting, and this machine adopts a unique track design, which can use multiple slots and one machine. This not only changes the shortcomings of low production of traditional light rail tipping machines, but also overcomes the high cost of transmission accessories for conventional gear racks and light rail driving tipping machines.

The chicken manure fermentation and tipping machine has the characteristics of good maneuverability and high output rate, which can effectively improve labor productivity, save manpower, and achieve the goal of reducing production costs and improving product quality; It is a new type of product with low investment and high returns; It also has functions such as stirring and crushing, and is an essential key equipment for fertilizer making enterprises. It largely replaces manual operations, reduces human labor, and improves work efficiency.

The first is NPK fertilizer granulator to produce compound fertilizer, so that the gas-liquid raw materials are absorbed and solidified, so that large particles and large pieces of solid raw materials are broken into fine powder, which is wrapped to form high-density particles with good fluidity, so as to prevent the powder from bridging and hardening due to moisture absorption, mutual electrostatic attraction, large contact area and other reasons, and also avoid the difficulty of gas-liquid raw materials storage and subcontracting, which is convenient for weighing , packaging and use.

Second: NPK fertilizer granulator makes the fertilizer form particles of appropriate size, which is conducive to the exertion of fertilizer efficiency. It avoids the disadvantages of bulk raw materials not easy to decompose, slow fertilizer efficiency, powder fertilizer easy to float and disperse, too fast decomposition and loss of fertilizer efficiency, and waste. At the same time, it also avoids the disadvantages of volatile gas-liquid raw fertilizer, easy to cause personnel poisoning and environmental pollution.
The granulation rate of npk fertilizer granulator is a combination of the amount of returned material and the particle size distribution of the returned material, the amount of liquid phase, the granulation temperature, the granulation time and other factors. The liquid phase content and temperature of the material from the granulator during operation also have a great influence on the granulation. If the liquid phase is not enough, the material will not bond into granules. If the liquid phase is too large, it will easily produce large particles, and the viscosity of viscous materials It has a lot to do with temperature. Generally, the higher the temperature, the greater the viscosity. When the temperature of the crystalline material is higher, the water is easy to volatile and easy to crystallize.
