Granulation technology of flat die granulator mixing straw manure

Materials processing of flat die granulator:
The raw materials of the flat die granulator are mainly feces (chicken, duck, pig, cow, sheep feces, etc.), straw (wheat, rice, corn, etc.), the raw materials are pulverized and fermented, and then other nutrients are added for granulation. .

Raw material fermentation before the production of flat die granulator:
The raw materials must be fermented and decomposed before they are granulated. After the straw manure is mixed, the fermentation is carried out to complete the harmless treatment, and the material is fully contacted with oxygen to raise temperature, deodorize, decompose, and decompose, and the utilization of microorganisms is utilized to improve fertilizer nutrients. Straw and fecal materials generally last for about 15 days and the fermentation is completed. After the fermentation, the screening machine is used to remove the impurities.

Flat die granulator granulation process:
The sieved raw materials are uniformly fed into a flat die granulator, and cylindrical particles are extruded under the extrusion of the mold. The organic fertilizer granules after extrusion granulation have moderate hardness and neat shape. The particles enter the rounding machine and rotate frictionally with the inner wall of the ball polishing machine. The shape is smooth and uniform in size, which is convenient for application. The flat die granulator has a low temperature change during processing and can better maintain the nutrient components inside the raw material. After the pellets are formed, the drying and cooling steps can be omitted, or still can be continued. After drying, cooling, and sieving, the package is stored.

The flat die granulator factory processes the manure to produce organic fertilizer, which is easy to operate and consumes low energy.The flat die granulation production line integrates fermentation and processing into one, and the technology is mature, and the value of the commercial organic fertilizer produced is high.Organic fertilizer products not only provide comprehensive nutrition for crops, but also have long-term fertilizer efficiency, which can increase soil organic matter and promote microbial reproduction.
