Application of cement ball mill . Balll mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials process.
To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifications depending on the end use. The packaged product is then shipped to the consumers.
