Going “Green” Using Steam

New Possibilities - Two topics of paramount importance to producers of mineral powders and other inorganic materials are the economical production of high quality products and the production of sub-micron powders in a dry state. Two new processes in the field of jet milling have been developed with this in mind. The article describe how the use of steam as a grinding medium provides significantly higher discrete energy input to increase size reduction capability in a jet mill, while using the properties of steam to enhance the classification process to produce material fineness that was previously impossible to achieve in a dry process.
