The raw material of flat die organic fertilizer granulator is mainly feces (chicken, duck, pig, cattle, sheep feces, etc.), straw (wheat, rice, corn, etc.), after crushing and fermenting the raw materials, then adding other nutrients to make granulation.
Raw material fermentation
After mixing straw manure, stacking fermentation was carried out to complete harmless treatment. The material is fully exposed to oxygen to heat up, deodorize, decompose and decompose by means of turning machine and fermentation agent, and the coordination of microorganisms is utilized to improve fertilizer nutrients. Straw and manure materials are usually fermented for about 15 days. After fermentation, impurities are removed by screening machine.
The sifted raw materials are evenly fed into the flat-die granulator, and cylindrical particles are extruded under the extrusion of the die. After extrusion granulation, the organic fertilizer particles have moderate hardness and neat shape. Particles enter the ball shaping machine and rotate and friction with the inner wall of the ball shaping machine. After rounding, the shape of the particles is smooth and the size is uniform, which is easy to apply.
The flat die granulator has low temperature in the process, and can better maintain the nutrients in the raw material. The drying and cooling steps can be omitted after the granules are formed. Can also continue to finish processing, drying, cooling, screening, packaging storage.
Flat die granulator is simple to operate and low energy consumption in the organic fertilizer production by industrial treatment of livestock manure. The technology of granulation and production line integrated with fermentation and processing is mature, and the value of commercial organic fertilizer produced is high. Organic fertilizer products not only provide comprehensive nutrition for crops, but also have long fertilizer efficiency, which can increase soil organic matter and promote microbial reproduction.
