In the organic fertilizer production process, there’s a piece of equipment that can be called a “pioneer in raw material processing”: the cage crusher. Despite its unassuming appearance, it can easily process all kinds of tough agricultural waste. It also seamlessly integrates with other fertilizer equipment, significantly improving fertilizer production efficiency. It’s no wonder it’s a favorite of many fertilizer plants internationally.
When raw materials like straw, branches, and discarded mushroom sticks are brought into the workshop, the cage grinder is the first to go into action. Its dual-cage rotor spins at high speed, and through the repeated impact and shearing of hammers and toothed plates, the coarse raw materials are pulverized into fine particles measuring 3-8 mm.Compared to conventional grinders, this machine produces a more uniform particle size and eliminates large impurities, ensuring smooth operation of subsequent equipment. It also easily handles raw materials with a slightly higher moisture content, preventing blockages and eliminating the need for frequent downtime and cleaning.
After the raw materials are pulverized, the horizontal mixer enters the picture. It mixes the pulverized material with fermentation agents, livestock manure, and other materials in precise proportions, ensuring even contact with the agents and preparing the material for fermentation. The mixed material is then fed into the fermentation area, where a compost turning machine automatically controls temperature and humidity, allowing microorganisms to rapidly decompose the organic matter in the raw materials.The prerequisite for all this is that the cage grinder can grind the raw materials into fine enough pieces, allowing the microorganisms to have a larger surface area to work, significantly shortening the fermentation cycle.
The fermented material is then screened by a drum screener machine to remove incompletely decomposed impurities before being processed into granular organic fertilizer by a granulator. You’ll notice that if the raw materials aren’t ground finely enough initially, the screener’s workload will increase significantly, and the granulator will also be prone to uneven granulation.
