Crusher, the main equipment of fertilizer production
The main process of compound fertilizer production includes crushing, mixing, granulation, drying and cooling, screening, packaging, etc. According to different fertilizer production process, the requirements of raw material particle size are also different. In the production of organic fertilizer, in order to speed up the fermentation reaction and improve the uniformity of raw material mixing, it is necessary to combine the fermentation raw materials in advance. In the process of chemical fertilizer production, in order to facilitate granulation, raw materials need to be further crushed before granulation. The unqualified large particles or a large amount of materials formed after granulation need to be crushed and returned to the granulation system. Therefore, fertilizer production needs different types of crushing equipment, commonly used crushing equipment are straw crusher, chain crusher, cage crusher, semi wet material crusher.
Straw crusher is suitable for cutting organic fertilizer raw materials, such as corn straw, rice straw, tobacco, peanut straw, sweet potato seedlings, branches and bark. The raw materials can be used not only for organic fertilizer production, but also for raising cattle, sheep and other livestock.
Straw crusher
Cage crusher is especially suitable for crushing materials with high hardness. It has simple structure, good crushing performance and strong sealing property. It is widely used to crush organic minerals, compound fertilizers and fertilizer granules.
Semi wet material crusher is mainly used to crush water pressure agent, such as fermented livestock manure, sludge, residue and other materials with water content of 25-50%, so as to make the particle size of crushed material meet the requirements of granulation.
Chain crusher is divided into vertical chain crusher and horizontal chain crusher. This machine is suitable for crushing raw materials and returning materials before granulation in chemical fertilizer production line. It is widely used in chemical industry, building materials, mining and other industries.

In the production of chemical fertilizer, the selection of crusher and the setting of parameters are determined according to the needs of crushing. Then the comminution technology and design of fertilizer production process are determined. Combined with the characteristics of the separator, a reasonable fertilizer granulation production line is designed to maximize the production efficiency. The selection of chemical fertilizer machine should be considered as much as possible, and attention should be paid to the problems of cost, energy consumption and efficiency.
