Grinding technology – not just for the Russian market

Summary: The attractiveness of the cement business, gaps in the market, high cement prices and the overall tremendous industrial growth that has taken place within Russia are all factors which have, over recent years, led several investors to express a desire to build new cement plants. At the beginning of 2009, Loesche GmbH had already supplied and commissioned more than 450 raw meal mills, including some in the CIS states.

The rated power levels of a cement raw material mill can reach up to 1000 t/h, a rate which ensures a constant supply of raw meal for modern kiln lines with only one mill.
