What are differences from the disc granulator and new type organic fertilizer pelletizer?

For granulators (round granules), many fertilizer companies use disc granulation or drum granulation to granulate materials. In fact, no matter what method we use, the purpose is to make materials into round granules (market demand). ), and then made into round particles to reduce the cost of consumption. According to our survey of fertilizer enterprises, more than 90% of enterprises that use livestock and poultry manure to make organic fertilizers use discs or drums for granulation, and the yield of these two types of equipment is 50-70%. The moisture content of materials is generally 50%-60%. This data is very reliable. I believe that those who have done fertilizer can basically understand these data.

The design principle of the disk  type of fertilizer pelletizer and the drum granulator is to let the materials stick together by themselves. These two types of equipment are mainly used in the granulation of chemical fertilizers and compound fertilizers, and the basic shapes of the materials are the same. In the early days, there were basically no professional organic fertilizer manufacturers in our country, but many farmers composted their own fertilizers, so the pan pelletizer for organic fertilizer production has only been gradually developed in recent years. At present, the main raw materials of organic fertilizers in the country are livestock and poultry manure, straw, sugar residue and other materials with relatively high organic matter content. These raw materials are all crude fiber materials. If the decomposing time is not enough, there will be more crude fibers, which will greatly affect the overall granulation effect of the fertilizer. Disc granulation and drum granulation use the rotation of the equipment itself to make the materials stick together to form granules, but materials with more coarse fibers cannot be granulated by themselves by rotating, even if the surface of the granules is rough.

The special stirring teeth granulator for organic fertilizer is a granulation equipment specially developed for organic fertilizer. The equipment is mainly composed of power part, feeding part and granulation part. Today, we mainly talk about the granulation part; the organic fertilizer granulator is mainly designed and manufactured for materials that are difficult to form and have more crude fibers. The material is sent to the granulation part, and the granulation part is equipped with an alloy cutter head. The material is ground between the cutter head and the inner wall to form a master batch, and the master batch enters the shaping area for further adjustment to form a complete particle. The coarse-fiber material can be effectively degraded by 80% after being matched by the alloy cutter head. Thereby improving the granulation effect!
