For grinding, lapping, and polishing bearing balls, roller races, and optical glasses, the main abrasive employed is alumina. Its abrasive characteristics are established during the furnacing and crushing operations, so very little of what is accomplished later significantly affects the features of the grains. Aluminum oxide is tougher than SiC.
Aug 30, 2019 Crushing mainly depends on the extrusion and impact of crushing equipment on materials, while grinding mainly depends on the impact and grinding on materials. Among them, grinding is a high energy consumption and low efficiency operation. The power consumption of crushing operation only accounts for 8-12 of grinding operation.
