    There are also 30-grit brazed metal and resin-based discs that grind less aggressively. Grinding produces vast amounts of cuttings. It is best done wet to eliminate the clouds of hazardous silica dust that are generated when concrete is ground dry. 3. Grinding of Clinkers. The cooled clinkers are received from the cooling pans and sent into mills. The clinkers are grinded finely into powder in ball mill or tube mill. Powdered gypsum is added around 2-3 as retarding agent during final grinding. The final obtained product is cement that does not settle quickly when comes in contact with water.
