The importance of particle density in passive pulsing air classifiers is examined. It had heretofore been assumed that passive pulsing classifiers separate particles according to density, although the assumption had never been tested. Theoretically, pulsing isolates the segment of the particle velocity curve where a denser particle falls faster than a less …

Through this specialized milling concept, product grinding is entirely autogenous. Steam jets alone create the grinding energy. No tool wear occurs! An integrated dynamic air classifier in the housing can be infinitely adjusted to the desired fineness. This guarantees exact adjustment of the grinding parameters and reproducible product quality.
