According to the survey, the utilization rate of chemical fertilizer in China is only 35% ~ 40%, and the rest is fixed by soil or leached by rain, causing environmental problems such as water pollution and lake eutrophication. In addition, chemical fertilizer is a kind of high energy consumption product, the price of raw materials rises and the environmental pollution is serious, which causes many small-scale chemical fertilizer plants to close down. However, due to the economic and energy conditions, the country is unable to transform these chemical fertilizer plants at present, which limits the increase of fertilizer production in China. Experts urgently call for reducing the use of chemical fertilizers, using more new biological fertilizers and applying more organic fertilizers. Farmers also urgently need a new type of fertilizer to meet the needs of agricultural production.

The chain crusher of organic fertilizer equipment adopts high-strength hard alloy chain plate with synchronous speed in the crushing process. The design of the inlet and outlet is reasonable, the broken materials are uniform, not easy to stick to the wall, and the cleaning is convenient. The crusher adopts the latest technology, selects high-quality steel and carries out system optimization design, with large output and high reliability. Organic fertilizer chain grinder has the characteristics of reasonable structure, fast feeding, stable performance and strong impact resistance.

Biological organic fertilizer production technology is to add biological agents to livestock and poultry feces and other organic materials (it is necessary to select the bacteria that reduce the ammonia gas in the production workshop during fermentation, otherwise it will cause great harm to the production environment and the production workers). After about two weeks of biological fermentation treatment, the harmless and commercialized treatment of livestock and poultry feces can be achieved, including complete deodorization, ripening, insecticidal and sterilization. This technology is especially suitable for breeding farms The planting base and the breeding industry are concentrated in the processing of livestock and poultry manure.
