Description

Technical Field

[0001] The utility model belongs to the technical field of white corundum production, in particular to a crushing device for white corundum production. Background Art

[0002] White corundum is made of industrial alumina powder and refined by modern new and unique technology. Sandblasting abrasive has the characteristics of short grinding time, high efficiency, good benefits and low price. Its main ingredients are aluminum oxide, and a small amount of iron oxide, silicon oxide and other ingredients. It is white and is made by high temperature melting in an arc of more than 2000 degrees and then cooling. It is crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes. It has a dense texture, high hardness, and sharp corners.

[0003] Since the smelted white corundum is a large block material, it needs to be processed into a powder structure before manufacturing ceramics, abrasive tools and refractory materials. Although the existing crushing device can crush and grind white corundum, the grinding efficiency is poor and white corundum particles will accumulate, which is not conducive to the subsequent grinding and use in the preparation of white corundum micropowder, resulting in a greatly reduced scope of application of the crushing device.
