Gridner for Powder Fertilizer Production
In the process of organic fertilizer production, pre fermentation raw materials are crushed by crusher in pre fermentation stage, pre granulation stage and re feeding stage. The diversification of organic fertilizer raw materials also drives the diversification of organic fertilizer equipment. There is no universal crusher. Different crushers are used for different materials. Organic fertilizer crushing equipment includes semi wet material crusher, straw crusher, vertical crusher, chain crusher and cage crusher.
So what kind of fertilizer crusher should be selected according to the materials?
1. Semi wet material crusher
The semi wet material crusher is a two-stage lawn fertilizer crusher with two-stage rotors. High speed rotating blades are used to crush fibers. It is mainly used for the fermentation of decomposed materials with water content of 30% - 60%, such as livestock manure, crop straw, urban waste, river sludge, kitchen waste and almost all organic fertilizer raw materials. The particle size after crushing can reach 20-30 mesh, which can meet the feed particle size requirements of general organic fertilizer granulation equipment.
The vertical crusher also has strong adaptability to the water content of materials, and can crush the water content of materials by 50%. In the processing of organic fertilizer, the crushing effect of humus, earthy lumps, dead branches, chaff, slag and so on is very ideal.
The straw crusher is mainly used for the chopping and processing of crop straw, branches with a diameter of less than 5cm and other plant straw. It can also be used for the chopping and processing of various crop straw and forage. It is mainly used in the pretreatment stage before organic fertilizer fermentation. This is because the smaller the particle size of the same substance with the same weight in the fermentation process, the larger the surface area. The larger the contact area between fermentation bacteria and objects, the faster the fermentation speed.
The chain crusher has simple structure and is mainly used for block crushing and high powder particle size. Based on the above characteristics, the chain crusher is mainly used for crushing and returning larger granular fertilizer after granulation in the production process of biological fertilizer project.
Cage crusher is mainly used for fine crushing operation, and even plays a mixing role in crushing. It is suitable for brittle materials, especially for crushing after powder agglomeration. The cage crusher can crush a variety of single fertilizers with water content below 10%, especially for materials with high hardness.
