Ball MillsThey have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig., 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller. Manufacturers use ...
The specific selection function effect on clinker grinding .../g, the specific energy is 40 kWh/t using 20 mm size balls. The created specific surface is influenced by the ball size. The curves diverge at different initial specific breakage rate. For a given specific energy consumption, the Blaine specific surface and the energy efficiency are greater with the 10 mm balls than with the 20 mm balls.
