Dust spillover while jaw crusher is working 2018-08-31 08:48

Shanghai Clirik Machinery has PE jaw crusher, PC hammer crusher and other models. The jaw crusher produced by our company mainly consists of steel plate casting and other types. Its crushing cavity consists of two jaw plates, the moving jaw and the static jaw. And the material is crushed under the extrusion of the moving jaw and the static jaw. Jaw crusher is widely used in quarries, mining, building materials, highways, railways, water conservancy and chemical industry, construction waste treatment, and other industries in a variety of ore and bulk material crushing.
This jaw crusher has become the first choice for ore crushing equipment because of its good crushing effect. However, someone who has used the crusher knows that a lot of dust often appears in the process of crushing and diffuses into the air, which not only destroys the ecological environment, but also seriously endangers the health of workers. Here are some tips for its causes.
1. Analysis of dust producing
The dust of the crusher mainly comes from the feed port, the discharge port and the conveying system. The material to be processed is extruded and crushed by PE jaw crusher, and then sent to the next step by a conveyor. In this process, a large amount of dust will be produced, and the concentration is very high. Driven by the air flow, the dust will diffuse to the surrounding area, causing serious dust pollution.
2. Cause of dust production at feed inlet
The crusher is not a fully enclosed equipment. In the process of feeding, it is inevitably for dust spillover to appear, which makes high concentration of dust be around the feed port.
3. Cause of dust production at discharge port
The crushed stone needs to be passed through the outlet into the conveyor. Because there is a certain drop between the feed port and the outlet, there will be a part of the stone powder into the air. At the same time, the stone powder will also be raised to the surrounding diffusion while the conveyor is working.
