The formula of organic-inorganic compound fertilizer refers to the content ratio of nitrogen, phosphorus and potassium of organic matter and the addition amount of other elements in organic compound fertilizer. Because organic-inorganic compound fertilizer is mostly used as base fertilizer, it actually refers to the ratio of organic matter to nitrogen, phosphorus and potassium in base fertilizer. Therefore, when determining the compound fertilizer formula in the organic fertilizer manufacturing process, two parts should be paid attention to. The first step is the ratio of organic matter to inorganic fertilizer, and the second step is to determine the ratio of various fertilizers in inorganic fertilizer.
1) Basis of raw material selection
Organic inorganic compound fertilizer is a compound fertilizer formed by adding inorganic fertilizer on the basis of organic materials. Therefore, it is necessary to select the appropriate ratio of nitrogen, phosphorus and potassium to determine the organic matter content formula of organic-inorganic compound fertilizer.
2) Determination of raw material proportion
Granulation equipment of organic and inorganic compound fertilizer
Double roller granulator is a granulating equipment designed by our factory, suitable for the processing of organic-inorganic compound fertilizer. The machine has been used by many fertilizer manufacturers, and the product quality is guaranteed. It can directly press powdered materials into granules under normal humidity. It is suitable for single-element fertilizers and multi-element compound fertilizers based on ammonium bicarbonate, urea, ammonium chloride, ammonium phosphate, potassium chloride, etc., and the resulting granules have high strength , No drying equipment is needed, which greatly reduces production costs.
