A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

It describe the cement particle are coarser or finer. Fineness of cement is defined as the property of cement that indicates particle size of cement and specific surface area of the cement. This property indirectly effects heat of hydration. Fineness must be in range between 5% to 10% of residue by weight.

Closedcircuit ball mills have been operated for cement milling for decades [[7], [8], [9]].Fig. 1 shows the process flow of a closedcircuit, twocompartment cement ball mill. The closedcircuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with opencircuit operation, where the ball mill is operated without the ...

The better mills on the market have an efficiency of about 89 % which means that only 89 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...
