Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...

Wear of grinding media. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement [3], as the wear of the grinding balls requires their substitution at intervals.

Mill internal design plays an important role in production efficiency. They not only protect the mill shell but also transfer the energy from the mill shell to the rotating charge of grinding media. The internal castings contribute upto 5% of the ball mill operating cost while the remaining 95% is from energy.

The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing. ... The working principle is that cement is removed from the mill before overgrinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a ...

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.

A dry operated, horizontal stirred media mill was used for the fine grinding of limestone and compared in open and closed circuit modes. It was found that the choice of grinding aids as well as the stirrer tip speed are crucial for the mill operation, especially in terms of the grinding efficiency and the transport behavior through the mill.
