Stirred mills

Stirred mills have been proven to provide energy savings when compared with traditional grinding mills. The finer the product required, the more efficient stirred mills will be. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines.

Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s.
