Description

Technical Parameters

Product Introduction

Alumina is the primary component of alumina grinding media balls, a type of ceramic filler. These goods are utilized as catalyst covers, supporting materials in reactors, and tower fillers. They are offered in a variety of specifications, sizes, and purities.

High temperature resistance, pressure resistance, little water absorption, and stable chemical characteristics define alumina ceramic ball.

Alumina grinding media balls can survive the temperature changes during the production process as well as corrosion caused by acids, alkalis, and other organic solvents.

Alumina grinding media balls' primary duties include expanding the gas or liquid distribution point and supporting and safeguarding the weak active catalyst.

Functional features

Alumina grinding media balls has the advantages of high hardness, large volume density, corrosion resistance, high temperature performance, high mechanical strength, no pollution to materials, good wear resistance and so on.

In addition, alumina grinding media balls under isostatic pressure can improve grinding efficiency better than natural pebble.At the same speed, ball and water ratio, the grinding time can be shortened, the single machine output can be increased, and the grinding production cost can be reduced.It is widely used in ceramics, glass, enamel, pigment, fine chemical industry, building materials, metallurgy, machinery, electronics and many other fields.

The hardness, strength and wear resistance of alumina grinding media balls are comparable to high aluminum ceramic ball.Its density is low and the grinding efficiency is relatively lower than the current high aluminum ceramic ball.However, its raw material cost is only about a quarter of the high aluminum ceramic ball, the sintering temperature is low, the production cost is not high.
