In the field of fertilizer production, the pulverizer is one of the key equipment, and its selection is directly related to production efficiency and product quality. For different scenarios such as organic fertilizer production lines, fertilizer production lines and NPK fertilizer production lines, selecting the crusher model according to the raw material characteristics is an important part of ensuring the smooth production.

For organic fertilizer production lines, the raw materials are mostly organic waste such as livestock manure, straw, and kitchen waste. Such materials usually have a high water content, high fiber content and soft texture. Therefore, when choosing a crusher, priority should be given to models with good adaptability and high humidity handling capacity. For example, some shredders designed with special tools and crushing chambers can effectively prevent material entanglement and smoothly break these organic raw materials to the ideal particle size, providing a uniform material basis for subsequent fermentation and granulation processes.

The raw materials in the fertilizer production line are more diverse and may include various ores, fertilizer raw materials, etc. At this time, it is necessary to choose the crusher according to the hardness of the raw material. For high hardness of ore raw materials, such as phosphate rock, etc., should be selected with a strong crushing capacity and wear parts of the crusher, such as jaw crusher or cone crusher. For some fertilizer raw materials with lower hardness, such as urea, potash, etc., hammer crusher or impact crusher can be used, which can achieve fine crushing of materials with higher efficiency.

In the NPK fertilizer production line, due to the involvement of nitrogen, phosphorus, potassium and other raw materials mixed grinding, the accuracy and stability of the crusher is required to be high. At this time, a grinder equipped with a precise screening device and an intelligent control system should be selected. Such a crusher can automatically adjust the grinding parameters according to the characteristics of different raw materials and the required particle size, to ensure that a variety of raw materials can be evenly and accurately crushed, so as to ensure the quality of NPK compound fertilizer stability.
