It is equipped with a storage silo, anti-clump crushing device, out-of-material adjustment system and conveying device. The function can transport the material at a uniform speed and can operate continuously. Especially suitable for large and medium-sized fertilizer plants. For the transfer and accumulation of organic materials during fermentation, it is also suitable for engineering applications such as aquaculture.
Loader feed hoppers are mainly used for mechanized feed and uniform delivery of raw materials. Raw materials can be supplied continuously by forklifts to reduce manual fatigue. There is a crushing and feeding device in the middle of the silo. There is too much material in the silo to start the crushing device. The spindle runs to crush the accumulated material, which makes the material fluffy and remains on the conveyor belt. It is suitable for the uniform transport of various solid materials and certain moisture materials.

Dehydrator

Some fermentation raw materials have too high water content, and dehydration needs to be treated before fermentation.
The machine can be widely used in chickens, cattle, horses, all kinds of animal and poultry manure, wine, starch residue, sauce slag, slaughterhouses and other high concentration for ganic wastewater separation. This machine after the solid liquid separation dehydration, low water content, the appearance of fluffy, no viscosity, no odor, no hand press. After treatment, animal and poultry droppings can be packaged or sold directly. The water content of animal and poultry manure after treatment is the best condition for the fermentation of organic fertilizer of animal and poultry manure, which can be fermented directly to produce organic fertilizer.
1。 The water content is between 80% and 90%, and the water content is between 40% and 50%.

NPK fertilizer production

How to avoid fertilizer clumps in NPK fertilizer production

Fertilizer blocking problems usually occur in the process of fertilizer processing, storage and transportation, and are caused by the absorption, dissolution, evaporation and recrystallization of fertilizer particles. In this process, a crystal bridge is formed, causing small particles to form large particles and clump.
So how to avoid the fertilizer clumps generated by NPK fertilization equipment?

1. Choose the right raw material.

Fertilizer production of raw materials, such as ammonium salts, phosphates, trace element salts, potassium salts, etc., mostly contain crystalline water, easy to absorb water, such as ammonium sulfate, phosphate, trace elements easy to reunite, insoluble in water. Urea is prone to extract water and clumps with trace element salts.

Choose raw materials that are not easy to clump and produce fertilizer that does not clump. For example, fertilizers with humic acid as the main raw material and amino acids as the main raw materials are not easy to clump. Also, try to keep the material dry when selecting it.

2. When producing NPK fertilizer, the water content and packaging temperature of the fertilizer should be reduced and the appropriate production time should be selected.

Fertilizer production is generally non-closed. During the production process, the greater the air humidity, the easier the fertilizer is to absorb moisture clumps. Fertilizer production avoids the rainy season and concentrates on fertilizer production on dry days. In the fertilizer production process, the raw material is heated by dryer, so that the water content of fertilizer is controlled at 0.6%, prolonging the cooling time of fertilizer, reducing the packing temperature, making the fertilizer not easy to clump.

3. Add anti-clumping agent to reduce the physical chemical reaction between NPK fertilizer particles.

The higher the room temperature, the easier it is to dissolve. In general, raw materials dissolve in their own crystalline water and cause clumps. Adding talcum powder, humic acid and other non-clumping powders can also be added some surfactants to prevent clumps.

4. Reduce the height of the fertilizer stacking and storage pressure.
The greater the external pressure of fertilizer, the easier it is for the crystal to clump in contact with the crystal, and the smaller the external pressure, the more difficult it is to clump.

5. The NPK fertilizer can be screened with a screening machine to further improve the uniformity of fertilizer particles.
NPK fertilizer particle size is not uniform, particle spacing is small, contact area is large, easy to reunite. If the pressure strength of fertilizer particles is low, deformation and breakage are easily occurred during packaging, transportation and storage, increasing the contact area between the particles, which can also lead to fertilizer clumps.

If the fertilizer plant uses NPK fertilizer production line to produce a large amount of fertilizer, can be used for two screening machines to obtain suitable fertilizer particles.

6. Production of NPK fertilizer particles.

Because of the small contact area between circular particles, it is not easy to crystallize the clumps. Therefore, the granulation of nitrogen and phosphorus potassium fertilizer is beneficial to the storage, transportation and fertilization of fertilizer.

When using roller granulators to produce NPK compound fertilizer particles, the dryer is not used, but the raw materials for the production of fertilizer must have good adhesion.

When producing NPK compounding particles with a disc granulator (or drum granulator), it must be dried and cooled.

Bio-organic fertilizer production process

Bio-organic fertilizer refers to the main raw material of livestock and poultry manure, inoculated with microbial complex bacteria, fermented and decomposed to completely kill pathogens, insects and eggs, fertilizers with microbial fertilizer and organic fertilizer effect, etc. Bio-organic fertilizer generally contains a lot of Nitrogen, phosphorus, potassium and other elements and calcium, magnesium, sulfur, iron, boron and other trace elements, as well as a large amount of organic matter and humic acid substances, make the fertilizer supply balanced. The bio-organic fertilizer production line processes the fermented material into the final organic fertilizer.
Raw material for bio-organic fertilizer production
The main raw materials for bio-organic fertilizer production are agricultural wastes such as livestock and poultry manure and crop straws.


Mixed ingredients in bio-organic fertilizer production

The source of raw materials, fermentation method and equipment are different, and the ingredients are also different. The specific formula depends on the source of the organic material. The general principle of ingredients is: the organic matter content of the total material should be greater than 30% (preferably 50%-70%), carbon to nitrogen ratio (15:1)-(20:1), pH value should be 6-7.5, including The water content should be around 50%, and the water content should be adjusted to 50%-70% during inoculation.

Fermentation maturity

It can be laid flat or fermented in a fermenter. Fermentation tanks are usually placed in closed or semi-closed fermentation chambers. The effect is better than flat ground. Every three days, you need to use a fertilizer turning machine to turn it regularly. After 25-30 days of fermentation, the temperature is gradually reduced from 70-80°C to stable, and the decomposition is completed.
