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.
Application of Cement Ball Mill : Cement ball mill is mainly used in grinding of cement finished product and materials, also to the metallurgical, chemical, electricity and other industrial and can be used to open streams, but also to the composition and the separator flow grinding circle.
Ball mills operate either in open or closed circuit. Open circuit operation is best utilized when: • Another stage of grinding follows the mill • Reduction ratio is small • Feed material is already fine and one pass through the mill produces the desired results • Product size control is .
