Brief Introduction
Alumina grinding ball is mainly used as grinding media and are widely used. According to different alumina contents, they can be divided into medium aluminum balls, medium-high aluminum balls, and high aluminum balls.
Medium-high aluminum balls and high aluminum balls are accepted by most ceramic factories due to their lower prices. They are mainly used for grinding ceramic blanks. High aluminum balls are widely used in different types of ceramics, enamels, glass, chemical and other factories for finishing and deep processing of thick and hard materials due to their high strength, high hardness, high wear resistance, high specific gravity, small size, high temperature resistance, corrosion resistance, and pollution-free. Among them, high aluminum balls with a content of 92 are the most commonly used.
Properties: Alias ceramic balls, porcelain balls, grinding balls, corundum balls, wear-resistant porcelain balls, high aluminum balls.
The appearance is white spherical, with a diameter ranging from 0.5 mm to 120 mm.
Features
➊The main component of this product is high-quality alumina with high whiteness, which has no effect on the quality of the ground material.
➋This product is formed by rolling and isostatic pressing, with a large specific gravity, which can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the effective volume of the ball mill, thereby increasing the amount of grinding material added.
➌This product has low wear and tear and can greatly extend the service life of the grinding body.
➍This product can withstand more than one thousand degrees high temperature, acid, alkali and corrosion resistance.
