Technical Field

[0001] The invention relates to the technical field of chemical raw material processing, in particular to a chemical raw material crushing device. Background Art

[0002] Chemical raw materials refer to the basic materials used to manufacture various chemical products in the chemical production process. These raw materials can be natural or synthetic and are widely used in chemical industry, pharmaceuticals, agriculture, food, daily chemicals and other fields. Common chemical raw materials include: organic compounds: such as hydrocarbons, alcohols, aldehydes, ketones, acids, etc.; inorganic compounds: such as acids, alkalis, salts, etc.; polymers: such as plastic raw materials such as polyethylene, polypropylene, polystyrene; catalysts: substances used to accelerate chemical reactions, such as metals such as platinum, nickel, aluminum or their compounds; solvents: liquids used to dissolve other substances, such as water, ethanol, acetone, etc. The selection and use of chemical raw materials are closely related to the properties, production process and cost of the final product.

[0027] Among them, a crushing groove is arranged through the inside of the crushing box body 4, and a grading filter 19 is fixedly connected at the center of the crushing groove. The grading filter 19 divides the crushing groove into an upper groove and a lower groove. A first-level crushing mechanism is arranged in the upper groove, and the first-level crushing mechanism includes a first rotating column 15 arranged in the upper groove, and the first rotating column 15 is rotatably connected to the side wall of the top cover 5.
