PRINCIPLE BETA-MILL The technical principle of the BETA-MILL is pressure grinding. By having defined feeding velocity, material height and width, a defined layer of material will be fed to the pressure transaction zone (grinding zone). Homogenity and ideal pre-airing assure the perfect utilitisation of the employed energy in the grinding process. In comparision to other pressure grinding mills ...
Grinding trends in the cement industry - Cement …
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 ...

OVER VIEW - Loesche
In 1935 Loesche supplied a first cement mill to Brazil. Then, the time was not yet ripe to estab-lish the grinding of cement in vertical mills. It was to be almost another 50 years before the cement industry introduced this modern grind-ing technology. The finenesses required for cements place the highest demands on the new grinding technology. Innovative engineers from Loesche came up with a ...

Cement mill - Wikipedia
A cement mill (or finish mill in North American usage) ... have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive ...
