Sep 10, 2016· Grate discharge single and two-compartment ball mills are widely applied types in cement grinding circuits. The ball mill can have three-compartments and it can be operated in open circuit without using an air classifier in the downstream of the mill. Third compartment of the mill is for fine grinding of cement.
Right circuit if cooling is not necessary - The static separator in the mill ventilation circuit is optional - The product of the separator goes directly to cyclones - Ventilation settings can be limited due to antagonistic objectives - Problems of the cement mill can disturb the performance of the separator -

circuits, where the product of the cement mill (CM) outlet is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to CM to be ground again. A simplified flow sheet, showing the basic
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.
The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill. The torque and time requirements of the mill with the ball
