Cement which is an essential construction material is sold in the form of grey or white
Greater efficiency, lower energy consump-tion, and maximum simplicity – these are the trends driving the development of grinding technology in the cement indus-try. Mills of various types are used in cement works, from grinding the raw material through to crushing the clinker into fine powder. Alongside vertical and
Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.
