Abstract

The invention relates to installations for grinding materials and can be used in the mining, agricultural, chemical and other industries. The purpose of the invention is to increase the efficiency of the grinding process by creating an additional pulsating movement of the material being crushed in the radial direction. In the housing 1 of the centrifugal-impact mill there is a rotor 2 with working bodies 3 and 4, on which plates 5 and 6 are installed parallel to the axis of the rotor 2, inclined to the radial planes of the rotor; plates tilted in opposite directions. The working bodies 3 with the plates 5 direct the material to be milled. The flow of air towards the center of the mill and the workers with 4 plates 6 from the center of the mill. This provides pulsating movement of the material in the radial direction and turbulence in the flow of air-material mixture, increasing the path of movement of the material and the number of its impacts on the working bodies 3 and 4, power 5 and 6 and the baffle plate 9. 1 h. nt fl1, 3 ill. with Q (L with

The invention relates to installations for grinding materials and can be used in the mining, agricultural, chemical and other industries.

The purpose of the invention is to increase the efficiency of the grinding process by creating a pulsating mixing of the material to be ground in the radial direction.

goes its initial grinding. Then, under the influence of gravity, the material enters the zone of subsequent grinding by the working bodies 3 and 4. The working bodies 3 use plates 5 to direct the material to be milled with air to the center of the mill, and working bodies 4 by plates 6 from the center of the mill, which provides pulsating movement of the material radially in directions, increasing the path of the relocation of the material in the mill and the number of impacts on the working bodies 3 and 4, plates 5 and 6 and the bumper plate 9 of the housing 1.

The creation of an additional pulsating movement of the material being crushed by the plates makes it possible to significantly increase the

FIG. 1 depicts the proposed direction and direction of turbulization of the flow of the milling-impact mill, the longitudinal-air mixture in the radial and axial section; in fig. 2 is a section A-A in FIG. one; ha fig. 3 is a section BB in FIG. one. ; The centrifugal impact mill comprises a housing 1 in which a rotor 2 with working bodies 3 and 4 is located. Working bodies 3 and 4 have plates 5 and 6 inclined to the radial planes of the rotor. On the working (adjacent) bodies 3 and 4, placed in the same horizontal plane, the plates 5 and 6 20 of the grinding efficiency are tilted in opposite directions

(Fig. 2). On neighboring working bodies 3 and 4 in the axial direction of the plate 5 and 6 are also tilted in counter-1. Centrifugal Impact Mill, slender sides (Fig. 2 and 3). Dimensions keeping the rotor enclosed in the housing with The plates, their number and the angles of rotation of the 5 working bodies and blades, differ depending on the purpose, searching with the fact that, to improve the efficiency of the mill. In order to feed the grinding process by creating a material on the accelerating blades 7 of the rotor 2 and the additional pulsating peremekorpus 1, it is equipped with a central loading of the crushed material into the injured pipe 8. For grinding the maternal direction, the blades are made in The rial in the housing 1 is installed baffle plates 9. Centrifugal impact mill operates as follows. The initial product through the nozzle 8 enters the blades 7, rotating together with the rotor 2, accelerates and, under the action of centrifugal forces, hits the burglar plate 9, resulting in plates that are mounted on each working element parallel to the rotor axis and inclined to the radial plane the rotor passing through the middle of the plates of the corresponding working body. 2. Mill according to claim 1, characterized in that the plates on adjacent working bodies are inclined to the radial plane of the rotor in opposite directions. FIG. 2 Compiled by L. Chubukova Editor G.

Project, 4 goes its initial grinding. Then, under the influence of gravity, the material enters the zone of subsequent grinding by the working bodies 3 and 4. The working bodies 3 use plates 5 to direct the material to be milled with air to the center of the mill, and working bodies 4 by plates 6 from the center of the mill, which provides pulsating movement of the material in the radial direction and turbulizes the flow of the air-material mixture in the radial and axial directions, increasing the path of the over-, material-bed in the mill and the number of its impacts on the working bodies 3 and 4, plates 5 and 6 and the end 9 plate housing 1. The creation of an additional pulsating movement of the material being crushed by the plates makes it possible to significantly increase the grinding efficiency plates that are installed on each working body parallel to the axis of the rotor and inclined to the radial plane of the rotor passing through the middle of the plates of the corresponding working body. 2.
