Abstract

The invention relates to a device for grinding materials. The purpose of the invention is to increase the intensity of the grinding process. The centrifugal mill comprises a housing 1, a vertical shaft 2 with a rotor 3 mounted on it, a drive 4 of an annular table 5 with lining 6, a pressure ring 7 and bouncing elements 8 in the form of balls, a loading nozzle 9, a separator 10, a nozzle 11 for discharging crushed material and a drive 12 rotors. The source material through the loading pipe 9 enters the rotor 3, which throws the material onto the fender elements 8, when struck, the material is crushed and under its own weight enters the ring table 5, from where it moves under the fender elements 8 by crushing and crushing by grinding elements. The finished product with the air flow passes through the separator 10 and enters the pipe 11. 1 Il.

Description

The invention relates to devices for grinding materials and can be used in the mining, chemical and other sectors of the industry.

The purpose of the invention is to increase the intensity of the grinding process.

The drawing shows a centrifugal mill, a general view.

The centrifugal mill comprises a housing 1, a vertical shaft 2 with an accelerating rotor 3 mounted on it, an actuator 4 of an annular table 5 with lining 6, a pressure ring 7 and baffle elements 8 in the form of balls, a loading nozzle 9. a separator 10, a nozzle 11 for discharging crushed material and rotor drive 12.

The mill works as follows.

The source material through the loading nozzle 9 enters the accelerating rotor 3, which throws the material onto the bumping elements 8, upon impact of which the material is crushed and under the action of

own mass enters the annular table 5, from where centrifugal forces are moved under the bumping elements 8 for crushing crushing and

abrasion The finished product with the air flow passes through the separator 0 and enters the pipe 11 of the outlet of the crushed material.

Claims (1)

Invention Formula A centrifugal mill, comprising a casing, an accelerating rotor located in it, concentric to which a breaker device with a rotation drive is installed, loading and unloading nozzles, which, in order to increase the grinding process, the mill is equipped with an annular table installed under the rotor, and a pressure ring located above the rotor, with the baffle device made in the form of rotation bodies mounted between the ring table and the pressure ring.
