AN AIR-JET MILL FOR FINE AND/OR CRYOGENIC MILLING AND SURFACE TREATMENT OF PREFERABLY HARD, ELASTIC AND/OR THERMOPLASTIC MATERIALS

摘要

the air jet mill with a grinding chamber and a pre - procedure for sorting cabinet, fine grinding (less than 10mu), as well as the cryogenic grinding and, in some cases, the surface treatment in the grinding of hard materials, preferably elastic, and / or the rmoplastiques.the facility uses little energy, does not contain any moving piece exposed to high wear, has a cabinet forming an integral part of the - vortex crushing space and using the energy remaining after grinding into the system, allowing a rigorous calibration of fi and the particles.
