They 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. 2.23, 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.
01.04.2010· Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...
The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well. It is known that only 2 to 20% of the energy is consumed by the grinding proper, while the rest is expanded on overcoming friction, on vibrations and is ...
