The following are the most common metallographic abrasives: Silicon Carbide. SiC is a manufactured abrasive produced by a high temperature reaction between silica and carbon. It has a hexagonal-rhombohedral crystal structure and has a hardness of approximately 2500 HV. It is an ideal abrasive for cutting and grinding because of its hardness and ...A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and improvement in grinding efficiency due to various grinding aids viz .polyols, amines .
