Description

The utility model relates to mechanical engineering, in particular, to impact - centrifugal mills, and can find application in the construction, mining, chemical, metallurgical and other industries for grinding ore and non-metallic materials.

Known working body (rotor) of a centrifugal crusher for brittle materials, containing a disk, a material distributor located in the center of the disk, radial accelerating blades and hammers mounted on the peripheral part of the disk so that their working surface is a continuation of the working surface of the accelerating blades (Auth. St. USSR No. 1685519, 02 C 13/16, publication 10.23.1991).

However, the known working body does not provide a high degree of grinding material. This drawback is due to the fact that the material from the distributor is thrown onto the accelerating blades, which are open from above, because of which part of the material does not fall onto the accelerating blades and does not acquire the speed required for splitting.

Also known is the working body (rotor) of an impact - centrifugal crusher, comprising a drum consisting of an upper disk with a central hole for inputting the starting material, a lower disk and a shell with windows for outputting accelerated material, inside of which there is a distributor of the starting material fixed to the lower disk, and chord accelerating vanes with end vanes (RF Patent No. 2188075, B 02 C 7/08, publication August 27, 2002).

However, the known working body does not allow to achieve a high degree of grinding of the material due to the fact that it provides only a single splitting effect on the material by imparting acceleration and impact on the breaker elements of the crusher.

The objective of the utility model is to increase the degree of grinding of the material by providing an additional splitting effect on the material.

The essence of the utility model is that to solve the problem by the specified technical result, the working body is shock - centrifugal

mills, containing a drum consisting of an upper disk with a central hole for inputting the starting material, a lower disk and a shell with windows for outputting accelerated material, a distributor of the starting material located in the central part of the lower disk, and chordate accelerating blades with end blades, characterized in that contains hammers or beats fixed to the peripheral part of the drum.

The utility model is illustrated by drawings: figure 1 - working body of a shock-centrifugal mill with hammers, plan view; figure 2 - section a - a in figure 1; figure 3 - the working body of the shock - centrifugal mill with bills, view in plan; figure 4 - the working body of the shock - centrifugal mill with bills, view in plan.

The working body of the shock-centrifugal mill contains a drum consisting of an upper disk 1 with a central hole 2 for inputting the starting material, a lower disk 3 and a shell 4 with windows 5 for outputting accelerated material, a distributor 6 of the starting material located in the central part of the lower disk 3, chord accelerating blades 7 with end blades 8, hammers 9 or beat 10, mounted on the peripheral part of the drum - to the shell 4 or in the window 5.

A utility model is used as follows.

The working body is rotated at the required working speed, and through the central hole 2, the source material is fed to the distributor 6. Under the action of the centrifugal force field arising in the rotating working body, the distributor 6 discards the material onto the chord accelerator blades 7, which accelerate the material. Material with high speed is removed from the drum through the windows 5, hits the bump elements of the mill (not shown in the drawings) and breaks into pieces. Pieces of material are reflected from the fenders and are hit by hammers 9 or bills 10, which carry out an additional splitting effect. Thus, hammers 9 or beat 10 can increase the degree of grinding of the material.

Claims (1)

The working body of a shock-centrifugal mill, containing a drum consisting of an upper disk with a central hole for inputting raw material, a lower disk and a shell with windows for outputting accelerated material, a distributor of raw material fixed in the central part of the lower disk, and chord accelerating blades with end blades, characterized in that it contains hammers or hammers, mounted on the peripheral part of the drum.
