<p>Air-jet mill provided with pregrinding chamber and inner sizer suitable for fine grinding (below 10ν) furthermore for cryogenic grinding and in a given case for surface treatment during grinding of preferably hard, elastic and/or thermoplastic materials. The facility representing the invention is an energy-saving unit, it does not comprise any moving components being exposed to heavy wear, has an inner sizer forming an integral part of the grinding space the former making use of the energy left after grinding in the system thus enabling a sharp sizing of fine fractions.</p> |
