Get PriceCement mill is the key equipment for grinding after the crushing process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grindable materials.
EF1 Dry Grinding for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced. The inefficiency factors for open circuit
