Description

Technical Field

[0001] The utility model relates to the field of chemical raw material grinding, and more specifically, to a chemical raw material grinding device for chemical industry. Background Art

[0002] In chemical production, chemical raw materials are the raw materials for chemical production and are used to produce chemical products. Chemical raw materials are generally divided into three forms: solid, liquid and gas. When solid chemical raw materials are used to produce chemical products, they need to be crushed to reduce the size of the chemical raw materials.

[0003] Based on the above, the inventors found that: currently, traditional chemical raw material grinding devices on the market do not have the crushing function themselves, and directly grind some chemical raw materials with larger particles, which is easy to cause insufficient grinding and slow grinding rate. In addition, the ground chemical raw materials are easy to stick to the surface of the grinding roller after grinding. If they are not cleaned, the grinding gap between the two sets of grinding rollers will be reduced after a long period of grinding, thereby reducing the grinding efficiency. Therefore, in view of this, the existing structure is studied and improved, and a chemical raw material grinding device for chemical industry is provided, in order to achieve the purpose of being more practical.
