Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages. However, they have higher energy demands. By using an appropriate kind of the more efficient roller mill technologies – either as a replacement or in combination with ball mills – considerable energy savings can be ...

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.
