The application of verticalrollermills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.
Since 1906 worldwide market leader in designing, manufacturing and servicing vertical roller mills for the cement, power and industrial minerals industries.
LOESCHE mill was presented to the industry in December 1999, this was another innovation and since than it has been copied by many gear makers. Before the introduction of the planetary gear technology, the standard drive design of Vertical Roller Mills (VRMs) comprised gear units featuring a bevel stage and two helical gear stages.

In the case of Slag grinding, the acceptance of roller press in finish grinding is well recognised. It offers the distinct advantage of saving of about 67 Kwh/t as compared to Vertical Roller Mill at 4200 Blaine. KHD has sold 27 Sag Grinding Circuits and maintains about 70 % market share in slag grinding in India.
In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency.
