A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.

Figure 1 presents a diagram of the cement manufacturing process using a rotary kiln and cyclone preheater configuration. The schematic for a rotary kiln and precalciner configuration is very similar to that shown in Figure 1, with a calciner vessel located between the rotary kiln and cyclone preheater.
