Alias: Ceramic ball, porcelain ball, grinding ball, corundum ball, high-aluminum ball. It is white spherical in appearance, with diameters ranging from 0.5 to 120 mm.
Use: It has high strength, high hardness, high flexibility, high specific gravity, small size, high temperature resistance, corrosion resistance and other excellent characteristics and is widely used in different types of ceramics, enamel, glass, chemical plants for post-hard material finishing and deep processing. It is a grinding medium for ball mills, pot mills, vibration mills and other crushing equipment. Its crushing and grinding efficiency and loss are much better than ordinary ball stone or ## goose soft stone.
Features:
1) The main component of this product is alumina, with high whiteness, and has no effect on the quality of the ground material.
2) This product is formed by rolling and isostatic pressing, with a high specific gravity, which can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the amount of grinding material added.
3) The product has low wear and tear and can extend the service life of the grinding body
4) The product can withstand a thousand degrees high temperature, acid, alkali and corrosion resistance.
