Description

The invention relates to devices for grinding materials and can be applied in the construction, mining and other industrial sectors and is an improvement of the invention according to bus No. 1031504.

The purpose of the Invention is to increase the efficiency of the mill operation.

The drawing schematically depicts 10 on the proposed rotary mill, a general view.

The mill contains a stepped body 1 with baffle rings 2 and a breaker on a rotating disk 17, the source material under the action of centrifugal forces is ejected with acceleration through the gap of the annular discharge plate 18 in a fan-like horizontal plane, forming a continuous ring layer, resulting in particles of the source material the impact forces act with the shell 14 of the dosing chamber 13- from the impact they split and are thrown into the dosing chamber 13, where they additionally wear out through the gap between the distributed strips 3, a stepped disk 15 casting cone 6 and an internal porotor 4 with beaters 5, a distribution cone 6, which can be installed eccentrically of the drive shaft 7, a loading nozzle 8, the lower part of which can be made as a cone 20, and a discharge nozzle 9. Internal the surface of the fender rings 2 and the outer surface of the discs: 10 of the rotor 4 can be made conical in shape and directed into the side of the loading nozzle 8. On the body 1 there is mounted a hopper 11 with outlets 12 and a metering chamber 13, the upper part Which is made in the form of a shell 14, the lower part 30 is in the form of a housing 15 mounted with a smaller base on the inlet 8, and under the outlet 12 of the bunker 11 on the distribution cone 6 is installed s horizontally and coaxially with the drive shaft 7 of the rotor 4 when using the vertical shaft 16, a disk 17, forming an outlet slot 1.8 with the lower edge of the hopper 11. In the outflow opening 12 of the bunker 11, the sleeve 19 is mounted movably in the vertical direction, moved by the handle 20, the housing 1 inside on the end walls

The top of the loading nozzle 8 of the housing 1 is uniformly loaded into the grinding chamber of the rotor mill on the billes 5 of the rotating rotor 4 and the bumper rails 3 of the baffle rings 2 of the rotor mill 1. where the main grinding takes place. The material crushed to the required size through the discharge pipe 9 of the housing 1 is sent to a material receiver (not shown). The loading dose of the source material into the grinding chamber of the rotary mill is determined by the size of the gap of the outlet slit 18. During the mill operation, the size of the outlet slit 18 can be adjusted by changing the gap between the disk 17 and the adjusting sleeve 19, moved in the vertical direction by the handle 20 in the outlet of the bunker 12 eleven .

Rotary mill works as follows.

The source material is loaded into the hopper 11 .. The drive shaft 7 of the rotor 4 is driven into rotation, the distribution cone 6 of which rotates the disk 17 using a vertical shaft 7. From the hopper 11 the source material is turned

given by bunker 11 to disk 17.
