The
flat die extrusion granulator is a new technology product developed by our factory based on years of experience in the design and production of organic fertilizer processing equipment. It is used for granulating various organic fertilizers after fermentation, breaking through the conventional organic granulation process. It is not necessary to dry and pulverize the raw materials before granulation, and the cylindrical granules can be processed by direct batching, which can save a lot of energy.
Materials processing of flat die organic fertilizer granulator:
The raw materials of the flat mold organic fertilizer 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. .
Fermentation of raw materials before production of flat die granulator:
The flat mold granulator must be fermented and decomposed before the organic fertilizer is 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, 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 sieve is used to remove the impurities.
Granulation production process of flat die organic fertilizer granulator:
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 circular throwing machine. The shape is smooth and uniform in size, which is convenient for application. The flat die granulator has a low temperature 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, and the finishing can be continued. After
drying,
cooling, and
sieving, the finish product 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 mold
organic fertilizer 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.
