Brown fused alumina grit is a form of brown corundum that has a relatively coarse particle size. In the preparation process of brown corundum grit, brown corundum usually need to be crushed, impurities removed and screened to obtain sand-like products of different particle sizes. Among them, the screening step is particularly critical. Through screening with different meshes, brown fused alumina of different particle size levels can be obtained, including coarse grit.

Because of its large particle size, brown fused alumina grit is often used in the rough processing stage of grinding, polishing and other processing processes to remove large uneven parts of the workpiece surface and lay the foundation for subsequent fine processing.

In addition, brown corundum coarse grit can also be used to prepare anti-skid materials. Because of its large surface roughness and high friction coefficient, it can effectively improve the anti-skid performance of the ground.
