In the process of organic fertilizer production line, raw material grinding is one of the key links, which directly affects the subsequent granulation and fertilizer quality. The characteristics of different raw materials are different, and it is necessary to choose the appropriate crushing equipment. Common chain mill, semi-wet material mill, cage mill and other advantages and disadvantages, reasonable choice can improve production efficiency, reduce energy consumption.
1. High humidity organic raw materials: Choose half-wet material crusher
For livestock manure, sludge, kitchen waste and other raw materials with high water content, it is recommended to use half-wet material crusher.
• Double blade structure, can efficiently crush wet material, avoid material clogging.
• Suitable for the production of organic fertilizer, especially for the crushing of high humidity materials after fermentation.
• Smooth operation, low maintenance cost, suitable for small and medium-sized fertilizer production enterprises.
2. Dry raw materials and brittle materials: Choose chain crusher
If the raw material is phosphate rock powder, urea and other chemical fertilizer raw materials, or dry organic fertilizer blocks, chain crusher is a better choice.
• High speed rotary chain crushing material, crushing effect is uniform, fine particles.
• Suitable for NPK compound fertilizer, fertilizer and dry organic fertilizer raw material treatment.
• Simple structure, wear resistance, suitable for mass production.
3. Raw materials with high fiber content: Choose straw crusher
For raw materials with high fiber content such as crop straw and wood chips, a professional straw crusher should be used.
• High speed cutting blade can efficiently crush long fiber materials.
• Suitable for straw composting, organic fertilizer production and biomass energy utilization.
4. Granular raw materials are crushed twice: choose cage crusher
In the production of organic and compound fertilizers, if the granular material needs to be crushed twice to make it more uniform, the cage crusher is the best choice.
• Suitable for fine grinding of NPK compound fertilizer particles to improve fertilizer uniformity.
• Compact structure, small footprint, low energy consumption.
