Medium alumina ball 40.50.60mm

Introduction: The product is made of superior Bauxite through the processes of extremely fine grinding, forming the particles by high temperature spray, getting the shape by equal static pressure and accomplishment by high Temperature burning in Roller Kiln. Application and characteristics: The product can be popularly used in ceramics, Oil, fine chemical Industry, construction material, Metallurgy, mechanical industrial, Electronics and other diverse fields. The product also has the advantages just like high hardness, proportion and mechanical Strength, perfect wearability and friendly to other material. It is the most Cost-effective product in the market. Advantages: It is more efficient to use the grinding ball made of alumina under the condition of equal static pressure than the natural pebbles and carbonized silicon ball. At the same rotate speed, percentage of water and material ball, the product can reduce the working time, increase the individual production, decrease significantly the cost.
