Description

Technical Field

[0001] The utility model relates to the technical field of color paste processing equipment, in particular to a color paste grinding device. Background Art

[0002] Color pastes are made from various pigments through rigorous processing techniques, including surface treatment and coating. Depending on the solvent used, color pastes are categorized as oil-based, water-based, and universal water-and-oil pastes. Oil-based pastes use pure oil as a binder, while water-based pastes use water as a medium with a surfactant to disperse the pigment filler. Due to the wide variety of paints and color pastes, a small amount of resin is often added during the preparation process to better disperse the pigment. During the color paste production process, the pigment, resin, and other raw materials must be ground into a powder.

[0003] However, current color paste grinding equipment mostly grinds it once, resulting in poor grinding effect. In addition, there are some larger particles in the ground raw materials after grinding, which affects the grinding efficiency. In addition, manual screening and re-grinding are required, which is not only time-consuming and labor-intensive, but also inefficient.

[0004] For this purpose, a color paste grinding device is proposed. Utility Model Content
