Grit size refers to the size of the abrasive particles embedded in the grinding wheel. It is a crucial factor that influences the wheel's cutting ability, stock removal rate, and the surface finish of the workpiece. Grit sizes are categorized into coarse, medium, and fine ranges. Coarse grits, with larger abrasive particles, are typically used ...

When materials enter between the two rollers from above, pressure (50-300Mpa) is transferred to materials by the hydraulic system through an oil cylinder, bearing seat, and rollers so that material particle size can be reduced by means of extrusion. After grinding, the fine particles less than 90μm account for about 20-30%.
