Description

A dust suppression device for mineral processing machine

technical field

The utility model relates to the field of mine machinery, in particular to a dust suppression device for a concentrator.

Background technique

In the field of ore processing, due to the large volume of the ore raw material itself, it is necessary to crush the ore to refine the ore for subsequent processing of the ore. Therefore, the crushing device is designed in the prior art, and the ore is processed by using counter-rotating crushing rollers. Under the action of extrusion force, the large ore can be refined and reduced. However, when the ore is crushed by a crushing device, there is a certain amount of dust on the surface of the ore itself, and dust will also be generated during the ore refinement process, so that when the crushing device crushes the ore, it is easy to produce a large amount of floating particles. Dust not only pollutes the surrounding environment but also greatly endangers the health of the staff working in this area. The beneficiation structure of the existing concentrator is fixed, and it is difficult and costly to add a dust suppression device inside. However, after the ore is crushed by the concentrator, it needs to be screened and stored for ores of different sizes. For the subsequent screening and other processes, we propose a A dust suppression device for a concentrator.
