Description

Technical Field

[0001] The utility model relates to the technical field of powder coatings, and more specifically to a crushing and grinding device for powder coating tablets. Background Art

[0002] Powder coating is a kind of coating in dry powder form. It does not contain solvents and is composed of solid resins, pigments, fillers and additives. Unlike traditional solvent-based coatings and water-based coatings, powder coating does not require solvents or water, but is applied through air suspension and electrostatic spraying.

[0003] Generally, powder coatings need to be tableted by a tablet press after extrusion, and the tableted raw materials are crushed and finally enter the grinding device for grinding, screening and bagging to complete the production of powder coatings. Existing grinding devices directly grind the raw materials. The sizes of the raw materials are inconsistent, resulting in different grinding times for each monomer raw material. Small raw materials need to wait until the large raw materials are ground before they can be discharged together. The work efficiency is low and the time is long. At the same time, when the ground coating powder is screened, the coating powder cannot be further graded, resulting in the mixing of powders of different particle sizes, affecting the stability of the product.
