polysius® booster mill
Bead mill working principle for dry cement grinding. One crucial characteristic of this mill is the high energy density, 10-20 times higher than of a ball mill, and the resulting very compact design. The bead-stirring elements on the shaft inside the fixed shell reach a tip speed of 5 times the critical speed.

Stirred Mills – Ultrafine Grinding
Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy …
Grinding
Table roller mills. Table roller mills work according to the principle of pressure comminution. The material to be ground is subjected to compressive stress between the grinding table and the grinding rollers, and is comminuted in the process. They are suitable for brittle/elastic grinding materials; the fineness level of the end product is ...
