Description

Sanding machine for paint processing

technical field

The application relates to the field of paint production, in particular to a sanding machine for paint processing.

Background technique

Coatings can be applied to a variety of substrates, from hard metal to soft leather. Surface coating determines the performance and quality of the product. High-speed dispersing equipment and grinding equipment are the two-wheeled carriages of the coatings industry. In order to reduce the process time, the sand mill is currently the grinding equipment with the widest material adaptability, the most advanced and the highest efficiency. The grinding chamber is the narrowest, the lever gap is the smallest, and the grinding energy is the most intensive, which can realize continuous processing of materials and continuous discharge, which greatly improves production efficiency.

The dispersing disc of the sand mill drives the grinding medium to move at high speed to generate friction and shear, so that the material is ground and dispersed. The grinding chamber needs to be cooled in time. There are horizontal sand mills and vertical sand mills, such as cylindrical rings. Gap sand mills and tower sand mills, etc., when cylindrical annular gap sand mills grind paint raw materials at high speed, friction and shear will occur, which will inevitably generate heat. If heat dissipation is not carried out, the paint grinding effect will be affected. .
