Patent number: 10926271Abstract: A grinding device including a rotor, mounted in rotational manner around an axle and having a plurality of blades extending radially relative to the axle. A sieve has a plurality of openings, with the sieve being mounted around the rotor so as to turn around the axle in the direction opposite the direction of rotation of the rotor. The rotor and sieve each has a height extending parallel to the axle and a width extending perpendicular to the axle wherein the width is between 1 mm and 20 mm. The rotation of the rotor and of the sieve is adjustable so as to reach a difference in circumferential speed between the rotor and the sieve between 100 m/s and 400 m/s, so as to reduce the average initial size of the crushed matter by a factor of 5 to 20.Type: GrantFiled: October 25, 2018Date of Patent: February 23, 2021Assignee: FREWITT FABRIQUE DE MACHINES SAInventors: Glenn Corminboeuf, Antoine Virdis

Publication number: 20180207642Abstract: 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.Type: ApplicationFiled: December 7, 2015Publication date: July 26, 2018Inventors: Antoine VIRDIS, Christophe PASQUIER, Glenn CORMINBOEUF
