In recent years, due to the increasing problem of environmental pollution, most factories, agriculture and aquaculture are prone to pollution. The development of organic fertilizer equipment has solved this problem well. In the past, organic fertilizer processing equipment was not advanced, and environmental governance may not be good. Under the active research work, new mechanical equipment will continue to appear, learn from each other and improve the performance of mechanical fertilizer processing equipment. With the development of these years, we can see the environmental protection of organic fertilizer processing equipment. At present, there is a special straw crusher in the organic fertilizer crusher, which is used for straw equipment to achieve the ideal purpose of crushing. Straw crusher is mainly used for cutting and processing cotton straw, bark, branches, corn straw, wheat straw and other biomass. The processed products can be used for power generation, papermaking, wood-based panels, extraction of n-hexanol, etc. Avoid entanglement of straw that you don't know how to deal with. The organic fertilizer equipment solves this problem, so that the product can be applied to other industries and play the role of waste utilization. Farm manure also has the corresponding special production and processing equipment, such as some cow manure, chicken manure organic fertilizer production and processing equipment, after drying and disinfection can produce organic fertilizer, and then applied to the farm, to provide the necessary growth nutrients for crops, so as to solve the pollution of fertilizer to the atmosphere, so that crops better growth.
