At present, 90% of the sand mills used in China are imported products, which generally have problems such as high prices, long supply cycles of accessories, and poor after-sales service. This requires domestic sand mills to fill the huge market gap. Sand mills are essential equipment in the process of adding matting agents and dispersing industrial coatings for their chemical fiber production. Currently, Dongguan Langling Machinery Factory, a domestic sand mill enterprise, offers discounted production prices.

Sand mill, also known as ball mill, is mainly used for wet grinding of chemical liquid products. According to its performance, it can be roughly divided into vertical sand mill, horizontal sand mill, basket sand mill, rod sand mill, etc. It mainly consists of the machine body, grinding cylinder, disperser, bottom valve, motor, and feeding pump, and the speed of feeding is controlled by the valve. The grinding medium of the equipment is generally divided into glass bead, zirconia glass bead, zirconia beads, etc. The feeding pump generally adopts gear pump, diaphragm pump, and other thick slurry feeding pumps.

Sand grinder is an efficient grinding and dispersion equipment widely used in industrial fields such as paint coatings, cosmetics, food, daily chemicals, dyes, inks, pharmaceuticals, magnetic recording materials, ferrites, photosensitive films, etc. Compared with grinding equipment such as ball mills, roller mills, and colloid mills, sand mills have the advantages of high production efficiency, strong continuity, low cost, and high product fineness. There are significant differences in process conditions, and the fineness requirements can be adjusted by adding or subtracting appropriate grinding media.
