Abstract

Use: The field of grinding materials in various industries. SUMMARY OF THE INVENTION: The movable working member is made of a set of disks of various diameters, between which are truncated guide cones. The fixed working body is made of sets of cylindrical spring-loaded shells fixed inside the body, respectively, by disks. The latter are made with a lateral surface at an angle of 5-10 ° C, and on its working surface, curtains located at an angle of 5-10 ° C. to the crusher axis. The crusher includes a housing with inlet and outlet nozzles. The inlet includes a guide cone. The rotor with the disks fixed on it is located inside the case. 1 hp f-ly, 3 ill.

Description

The invention relates to the field of grinding materials and can be used in various industries, mainly in the crushing of minerals.

A known crusher comprising a frame, a housing inside which are installed an external and internal working bodies connected to the drive, and a device for regulating the discharge gap. The closest in technical essence and the achieved result is a crusher containing accelerating discs mounted on a common vertical shaft located in a vertical chamber having concentrically arranged annular working surfaces.

The design of the discs makes it difficult for the material to penetrate into the gap between the discs and the annular working surface, which reduces the efficiency of crushing.

The aim of the invention is to increase the efficiency of crushing.

Performing an angle of 5-8 ° between the generatrix of the conical surface and the axis facilitates the penetration of the material into the gap between the outer and inner working surface.

Performing a flute at an angle of 5-10 ° contributes to the material being drawn into the gap between the vigone and the inner working surface, which contributes to an increase in the efficiency of crushing.

figure 1; on fig.Z - view along arrow B of the conical surface in figure 1.

The crusher includes a housing 1 with a loading 2 and a discharge 3 branch pipes located in the upper and lower parts of the housing 1, inside which the fixed working body is installed as a set of shells 4 rigidly spring-loaded 5 on the housing 1. On a vertical rotor 6 a set of discs 7 of different diameters with truncated guide cones 8 located between them.

Crusher works as follows. The material flows through the loading nozzle 2 by means of a truncated guide cone 8. Next, the material is drawn into the gap between the conical surface of the disk 7 and the shell A, where it is crushed to a size corresponding to the gap between them. The material crushed in the first stage with the help of a truncated guide cone 8 is fed to the second stage, where the gap between the disk and the shell is smaller than in the first stage. And so on, before grinding the material to the desired size. The crushed material is discharged from the housing 1 through the discharge pipe 3.

In addition, if necessary, you can provide for the removal of crushed mat; rial from any grinding stage, which will allow for a continuous crushing process to obtain a material of any size

Using a crusher will improve the efficiency of the crushing process.
