Ore crusher

Abstract

The invention provides an ore crusher. The ore crusher structurally includes a baffle, a rotating shaft, a crusher body, an external power attachment wheel, side seat plates, a dust reduction crushingdevice and a convex pressing roller; and the convex pressing roller meshes with the dust reduction crushing device, the top end of the baffle is movably connected with the crusher body through the rotating shaft, and the external power attachment wheel is installed on the right side surface of the crusher body in an embedded mode. In the process of meshing the dust reduction crushing device withthe convex pressing roller, after ore blocks are crushed, micro-particles are raised due to drop of the falling of crushed materials, an ejection and pressing mechanism replenishes internal water flowin a backflushing mode in the crushing process, after the crushing is completed, the internal water flow is released through the cooperation of a pressure replenishing release mechanism and an ejection dust pressing mechanism, the raised micro-particles are suppressed in a backflushing mode, the air concentration inside the crusher body can be reduced, the consumption of internal lubricating oilis stabilized, and a good external working environment is maintained.

Description

technical field [0001] The invention belongs to the field of ore machinery, and more specifically relates to an ore crusher. Background technique [0002] After the ore is mined, its size is uneven. Generally, the ore needs to be crushed by a crusher to form ore blocks of almost the same size, which can be easily transported and loaded. When the ore blocks are squeezed together, more micro-particles will be produced. [0003] Based on the above description, the inventors found that the existing ore crusher mainly has the following deficiencies, such as: [0004] After the ore block is broken, part of the microparticles will be attached to the crushing wheel and part will be attached to the ore block, and both of them are easy to be raised under the action of the two-way kinetic energy of the crushing wheel when the ore block is broken, thereby making the air The turbidity of the crusher rises and will extend from the inside of the crusher to the outside, which will intensi...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a kind of ore crusher, to solve the existing problem that after the ore block is crushed, part of the microparticles will be attached to the crushing wheel, and a part will be attached to the ore block. It is easy to be raised under the action of the two-way kinetic energy of the crushing wheel when crushing ore blocks, which will increase the turbidity of the air and spread from the inside of the crusher to the outside, which will intensify the consumption of internal lubricating oil and affect the external working environment.
