Product Introduction

Details

High Alumina Ball refer to bauxite, roller powder, industrial alumina powder, high-temperature calcined alpha alumina powder and other materials as raw materials, after batching, grinding, powder making (pulping, mud making), forming, drying, firing .Ceramic ball is a ball stone that is widely used mainly as a grinding medium. It has the characteristics of high density, high hardness, high wear resistance, high toughness and corrosion resistance.

Advantage

1. No pollution, no adverse effect on the quality of the ground material;

2. Using rolling and isostatic pressing molding technology, high density, high specific gravity, can greatly improve the grinding efficiency, and at the same time increase the effective volume of the ball mill, thereby increasing the amount of grinding materials added;,

3. It has excellent characteristics of high temperature resistance, acid resistance, alkali resistance and corrosion resistance;

4. Alumina ceramic ball is an ultra-low wear ceramic ball, the self wear is only 1.5/10,000, which greatly prolongs the service life of the grinding ball, thereby reducing the cost of customers.

Application

High Alumina Ball is suitable for high-grade grinding media and fillers for fine powder processing equipment in ceramics, cement, chemical paint, coatings, pigments, medical treatment, cosmetics and other industries where the ball mushroom machine and dust equipment used for grinding ceramic raw materials are relatively abrasive.

In order to effectively crush the material, the principles that must be followed when determining the grading?

First of all, the high-alumina balls must have a large enough impact force so that the high-alumina lined ball mill has enough energy to crush the granular materials, which is directly related to the maximum ball diameter of the high-alumina balls.

Secondly, high alumina balls must have enough impact times on the material, which is related to the filling rate of high alumina balls and the average ball diameter. When the filling amount is constant, on the premise of ensuring sufficient impact force, the diameter of the grinding body should be reduced as much as possible, and the number of high-alumina balls should be increased to increase the number of impacts on the material, so as to improve the crushing efficiency.

Finally, the material has enough residence time in the high-alumina lined ball mill to ensure that the material is fully crushed, which requires the high-alumina balls equipped with a certain ability to control the flow rate of the material.
