Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a grinding machine for powder coatings with high efficiency and low consumption. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.

[0003] During the processing of powder coatings, the raw materials often need to be ground and refined. The grinding machine is prone to heat up during use. Some components in powder coatings are heat-sensitive substances and are easily affected by high temperatures. Therefore, the heat generated during the grinding process will have a certain impact on the powder, resulting in poor use effect. Utility Model Content
