PROCEDURE FOR MATERIAL MILLING AND GRINDING MILL FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC B02C13/14 B02C13/30 

FIELD: machine building.

SUBSTANCE: grinding mill has a cylindrical housing 1 with an upper cover 2 and lower internal circular protuberance 3 with windows 4. The perforated cylinder 5 is fixed on the protuberance and covered with a ring 6. The shaft 8 is connected with a bowl-like rotor 9. The rotor has radial partitions 10, screens 11 and bent from the centre a horizontal section 12 above the protuberance. The braking device 14 consists of the journal 15, motionless beam 16 with a taper internal surface and bearing assembly 18, press disk 17 with a bearing assembly 19, restoring spring 20 and lever 21. The lever on the motionless articulated support is connected to the disk through the bearing assembly. The disk with taper external and internal cylindrical splined 23 surfaces rests on the spring. The spring is installed on the beam. The journal of the beam bearing assembly is located on one axis and is rigidly connected to the housing cover. The journal via external splines 24 contacts with the disk. According to the milling method the working space is continuously fed with the material at rotation of bowl-like rotor. The housing of the grinding mill is periodically decelerated and accelerated with a time ratio 0.03-0.1.

EFFECT: invention increases the output due to liquidation of stagnant zones and creation of high intensity of impact of material pieces at circulating motion.
