Stirred mills

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.

To offer a solution, RETSCH developed the High Energy Ball Mill Emax – which is able to grind many different substances to particle sizes < 100 µm and usually in a much shorter time than required by other ball mills. Ideally, the grinding breaks can be skipped altogether, which results in enormous time savings.
