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.
Sep 06, 2006· In this paper, based on analysis of the chemical and physical processes of clinker formation, a heat flux function was introduced to take account of the thermal effect of clinker formation. Combining the models of gas−solid flow, heat and mass transfer, and pulverized coal combustion, a set of mathematical models for a full-scale cement rotary kiln were established.

Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss. Removal of clinkers from the water wall is difficult thus requires pneumatic hammering. Low quality coal having less gross calorific value, high mineral content, high ash content, and the over-firing of molten slag are causes of clinker formation.
