Operating experience with the new Polysius-Quadropol~2 raw mill

摘要

In 1999 the Polysius roller mill Quadropol was introduced onto the market with the target to offer a vertical roller mill (VRM) of highest reliability which allows feeding of a 10000 tpd clinker line by a single mill. After many references in 2008 for Gulf Cement in the United Arabian Emirates a Quadropol QMR 61/30 with an installed drive power of 7000 kW was commissioned, and thus was the world's largest vertical roller mill at that time.
