SIEVE SYSTEM FOR A GRINDING DEVICE, AND GRINDING DEVICE USING THIS TYPE OF SIEVE SYSTEM

摘要

A sieve system for a grinding device permitting the processing of materials in terms of particle size, in particular the processing of solid or powder materials. The system includes a filtering portion having fine holes and designed to cooperate with a rotor of the grinding device in such a way as to press the material to be ground through said filtering portion; and a support portion having large holes, which is able to reinforce the filtering portion. The sieve can be coupled to a vibratory device. The sieve system allows for the grinding method to be operated in continuous mode, with a material flow rate through the sieve up to 50% higher than that reached with a conventional sieve.
