Description

one

The invention relates to the fine grinding of materials by cone crushers - and can be found in-use in the separation compartments of the dressing plant.

Cone crushers are known, comprising a housing, a fixed cone, a crushing cone mounted on a shaft eccentrically connected to the actuator, while the shaft in the lower part has a support {.

The closest technical solution to the invention is a cone crusher for fine grinding of the material, including a housing, a fixed cone, a crushing cone mounted on a shaft, eccentrically connected to the drive {2.

With the eccentric movement of the crushing cone between it and the stationary cone, the material is crushed, and the bottom support of the crushing cone is the surface of the stationary cone. The gap between the crushing and fixed cones is controlled by the axial movement of the draw cone relative to the fixed one.

The disadvantages of this crusher are IB significant material overgrinding, sticking overcrushed material to the walls of a fixed cone, which leads to a significant performance.

The purpose of the invention is to increase the productivity of the crusher and eliminate over-grinding of the material.

This is achieved by the fact that the crusher is equipped with rings installed with the possibility of contacting and coaxially facing one another to the crushing cone shaft and S body, with this, the outer diameter of the ring mounted on the crusher cone shaft is less than the internal diameter of the ring (located in The ring, located on the crushing cone shaft, is preferably spherical.

The rings provide an adjustable gap with a meleed crushing cone and a fixed cone surface, which contributes to an increase in crusher productivity, reduction of overgrinding and sticking of material to the walls of a stationary cone.

In the drawing, an engraving crusher is shown, a longitudinal section.

The crusher includes a housing 1, a tumbler 2, in which on tapered roller bearings 3 there is fixed a drive shaft 4 with an eccentric hole in the lower part, which includes a shaft 5 with thrust 6 and ROLE1 radial spherical 7 bearings and (Dust seal 8 sleeve. On the shaft 5 it is strengthened crushing cone 9 using a conical sleeve 10 and

nuts 11. The shaft 5 is held in the shaft hole 4 by a nut 12 having a malezt 13. In iKoipnyce 1 and on the shaft 5, coaxially with respect to one 1K to the other and with possible contact P01va; The ring 15 located on the shaft 5 is preferably spherical, and its outer diameter is less than the inner diameter of the ring 14 mounted in housing I. A fixed cone 19 is pressed to the lower floor of the housing 1 through an adjusting gasket .16 ic using an outer cone 17 and bolts 18 In case 1 has pipe 20 for supplying starting material.

Works crushed. As follows.

From the drive motor (not shown), the rotation is transmitted to the drive shaft 4, and the shaft 5 with the crushing cone 9 at the end eccentrically rotates relative to the stationary cone 19, while the ring 15 located on the shaft is in contact with the eccentric rotation of the shaft 5 with the ring 14 installed in the housing 1, and excludes the contact of the crushing 9 and the fixed 19 cones. Exact adjustment of the gap between them can be accomplished by varying the thickness of the gasket 16. The raw material is loaded through the nozzle 20, crushed in the working wedge between the crusher and the fixed cone and removed along the entire perimeter of the crusher cone. The crusher allows, in comparison with the known ones, to obtain a material of 0.1-1.0 mm at high productivity and to avoid overgrinding of the material and sticking it onto the walls of the fixed cone.

Claims (2)
