Description

The invention relates to devices for crushing rocks and can be used in mining, construction and other industries.

The goal is to increase productivity.

The drawing shows a crusher, a longitudinal section.

The centrifugal crusher contains a housing 1, inside of which a rotor 2 is installed. The crusher contains three grinding stages, each of which is made in the form of upper 3 and lower 4 disks mounted on the rotor, between which there are accelerating partitions 5, and a breaker ring 6 located in the housing Each grinding stage is provided with a central feed opening 7. The diameters of the disks 3 and 4, the diameters of the central feed openings 7 and the diameters of the baffle rings 6 are reduced in steps from top to bottom. A loading funnel 8 is installed in the upper part of the housing 1, and a discharge chute 9 is made in the lower part of the housing 1. In this case, the central loading hole in the lower disk 4 of the upper stage is equal to the central loading hole 7 of the middle stage, and the central loading hole in the lower disk 4 of the middle stage equal to the Central boot hole 7 of the lower stage.

Crusher works as follows.

Rotor 2 receives rotation from the drive. The material to be crushed is fed into the feed hopper 8, and the stub, under its own weight, goes down into the central feed holes 7. As

Since the diameter of the central loading openings 7 decreases in steps in the direction from top to bottom, the material simultaneously enters the lower disks 4 of each step. The diameters of the central loading openings 7 are selected so that the amount of material falling on the lower disks 4 of each step is approximately equal. In rotary disks 3 and 4, the material moves under the action of centrifugal force along radial accelerating baffles from the center of the disks to their periphery and impacts on the breaker rings 6. When the material is destroyed, the crushed pieces are spilled down and through the unloading trough under their own weight 9 is removed from the mill. Reducing the diameters of the disks 3 and 4, the diameters of the central feed openings 7 and the diameters of the breaker rings 6 in steps in the direction from top to bottom allows increasing mill productivity due to simultaneous grinding at all stages.
