Description

Technical Field

[0001] This utility model relates to the field of grinding machines, specifically a basket grinder for paint production. Background Technology

[0002] In the paint production process, basket mills are required. The working principle of a basket mill is as follows: A self-priming impeller is installed at the inlet of the grinding basket. When the motor drives the self-priming impeller to rotate at high speed, it generates a strong suction force and vortex effect. This strong suction force can draw the material to be ground into the grinding basket, preparing it for subsequent grinding and dispersion. The grinding basket is filled with an appropriate amount of grinding media, such as zirconia beads. After the material is drawn into the grinding basket, the grinding media also move under the high-speed movement of the stirring rod or lever impeller inside the grinding basket. Strong collisions, friction, and shearing effects occur between the grinding media and between the grinding media and the material, thereby gradually grinding the particles in the material into finer particles, achieving the purpose of grinding.

[0003] When a basket mill disperses and grinds paint slurry, the slurry inside the barrel tends to settle at the bottom of the grinding basket due to its high density. This prevents the material from fully contacting the grinding media in different areas of the barrel, leading to uneven grinding and reduced grinding speed. Utility Model Content
