1. Strictly control the nature of the feed

The control of feed properties mainly includes three aspects:

• One is to prohibit the entry of super-hard materials, and at the same time, it is strictly forbidden to enter the granulation chamber of non-crushed materials during production.
• The second is to control the particle size composition of materials, prohibit the entry of materials with excessive particle size, and screen in advance.
• The third is to control the moisture content of the material, and to treat the material with a lot of water in the sun, drying, etc., so as to prevent the material from sticking to the inner wall of the granulation chamber.
