Our wide range of products includes Cement Plant Complete, Close Circuit Type Cement Plant, Open Circuit Type Cement Plant, Air Classifier, Air Separator, Horizontal Flow Type Air Separator, etc. These are widely demanded for various applications in Cement, Paper, Pharmaceutical and other industries.Cement Mill Overview. A cement mill is the equipment that used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls.Jul 04, 2020 14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.
