Dry Grinding in the Submicron Range General This innovative steam jet mill is capable of fine grinding all kinds of dry products with any hardness and virtually no contamination. 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. Even the hardest of products poses no problem for this machine. In addition, moist products can be ground and dried simultaneously without any additional pre-drying process for inlet. The increasing interest in finer, dry products has led to the development of economical dry-grinding processes down to the submicron range. The s-Jet®® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d50 0.2 µm) can now be achieved with fluidized bed jet mills, which was only possible by means of wet media milling process at the past. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet®® System uses superheated steam as its milling gas.
