The gas distribution in the quadropol ® QMR² mill can be adjusted to the required operating conditions. This allows the specific gas flow rate and the pressure drop in the grinding system to be reduced. As a result, this second mill generation achieves an even lower energy consumption than the first generation.
The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill. Therefore, ease of replacement and regeneration is a major feature of the mill. With our proven Lift-and-Swing System, wear parts can be replaced rapidly through one single maintenance door.
