Cement mill - Wikipedia

In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered. As a general rule, the size of media has to match the size of material being ground: large media can't produce the ultra-fine particles required in the finished cement

2) The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with diameter less than 2 mm; Gradation of Grinding Media. The gradation of grinding media is also an important factor in improving the efficiency of ball mills. A reasonable ...

Cement Kilns: Size Reduction and Grinding

In the case of cement made by ball mill, the dissipation of all this heat becomes a major technical problem in itself, the energy being sufficient to raise the product temperature by 150°C. In grinding cement, tumbling mills are most efficient in the early stages of grinding, and the energy requirement rapidly increases with the fineness of the product. The "standard" curve for well-tuned ...
