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. most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
you can even help mills keep their variety up by putting a warehouse nearby that "gets" food types (with small maximum allowances) and accepts no other goods. then when the mill sells its last haunch of meat it has a nearby source of other food to quickly replace it. this obviously doesn't work if you don't produce a food surplus.

working principle of cyclone preheater: it utilizes the high-temperature airflow accumulated in the kiln and adopts multi-stage circulating suspension preheating method to make the raw material powder and the hot air flow exchange heat well complete the suspension preheating and partial raw material decomposition and prepare for the raw material into the kiln calcination.
a development of this process is the 'precalciner' kiln. most new cement plant is of this type. the principle is similar to that of the dry process preheater system but with the major addition of another burner or precalciner. with the additional heat about 85%-95% of the meal is decarbonated before it enters the kiln
