Within the content of this work, sampling campaigns were organized around a cement grinding circuit and each of the three grinding aids at varying dosage rates were tested. Then the ball mill and the air classifier were modelled by using perfect mixing approach and Whiten''s equation respectively.
In powder grinding plant, ball grinding process flow includes crushing, milling,air classifying,packing,silos,bucket elevator,conveying,etc. Grinded material discharges from outlet grit fluently. Ball grinding mill is Formed a closed system with air classifier.
Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
All these calculators are reliable, but Users need a certain experience to implement results of these calculators . Sizing equipments and mill''s optimization are the job of material suppliers and experienced engineering offices.
The energy efficiency of ball mills for use in finish grinding is relatively low, consuming up to 3042 kWh/ton clinker depending on the fineness of the cement (Cembureau, 1997;Marchal, 1997).

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
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.
Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. .
