Alumina Grinding Ball

Alumina grinding balls are higher than that of ordinary alumina ball. When working, the ball does not contaminate the grinding material, so it can maintain the purity of the grinding material and improve the stability of the grinding material, especially the ceramic glaze. High density, high hardness, high grinding characteristics, save grinding time, expand grinding space. Therefore, the grinding efficiency can be improved.

Introduction

The wear resistance of alumina ball is higher than that of ordinary alumina ball. When working, the ball does not contaminate the grinding material, so it can maintain the purity of the grinding material and improve the stability of the grinding material, especially the ceramic glaze. High density, high hardness, high grinding characteristics, save grinding time, expand grinding space. Therefore, the grinding efficiency can be improved. The wear resistance of alumina ball is higher than that of ordinary alumina ball.

High density, high hardness, high grinding characteristics, save grinding time, expand grinding space.

Advantages

Alumina grinding balls as ginding materials of precision object have many excellent performance, such as excellent abrasion resistance, high purity, excellent corrosion resistance, energy saving of grinding and dispersion.

Firstly, Alumina balls' abrasion resistance is higher than the zirconia beads when the high hardness ceramics are ground. Second, the purity of the alumina beads is 99.99% or more. When grinding, no contamination other than alumina. And then, it is excellent in corrosion resistance to the acid and the alkali. No performance deterioration in the warm water. At last, the density of alumina is 2/3 of the zirconia bead, and the filling weight to the mill is 2/3. In addition, the consumption energy when grinding can be decreased.

Application

Alumina grinding balls can be widely used in Dielectric, Piezoelectric, MLCC and other electronic materials, rare earth phosphor material, electrode material of Lithium battery and other battery application, electronic ceramics, sapphire ,transparent ceramic materials, pigment, ink and other materials, medicine, pesticide, antibacterial materials, powder food type nano materials, and also can grind high purity quartz sand, quartz crucible raw material. _20221103165601
