For contamination-free grinding NETZSCH Trockenmahltechnik has a new wear-protected version of the well-known Classifier Mill CSM in its program. With the so-called Ceramic-execution, contamination of the product being ground with metal is no longer a problem! All machine parts in contact with the grinding product are completely made of ceramic or have a ceramic lining.
The classifier mill CSM is a combination of a mechanical fine impact mill and an integrated dynamic air classifier. Using this air classifier a very fine final fineness of less than 10µm can be obtained, without the disadvantage of an external grinding and classifying circuit. The internal circulation of the coarse product in the classifier is self-adjusting, which leads to a steady, energy and space saving operation. The grinding is carried out between a peripheral milling track and the beating tools.
Thanks to the highly-developed classifier technology with vertical shaft, a rotationally symmetrical classification can be achieved, which guarantees a very high fineness with precise upper particle size limit as well as an even loading of the classifier wheel.
