Causes of Jaw Crusher Dust

Issue Time:2019-12-03
Ding Bo heavy industry jaw crusher mainly includes PE jaw coarse crusher, PEX fine jaw crusher, PEW European version jaw crusher and other models. Jaw crusher is commonly known as jaw crusher. The jaw crusher produced by Ding Bo Heavy Industry mainly includes steel plate casting and other types. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw. Complete the crushing process of the material. Jaw crusher is currently widely used in the quarry, mine manufacturing, building materials, highway, railway, water conservancy and chemical, construction waste processing, and other industries in the crushing of various ore and bulk materials. The highest compressive strength of the crushed material is 320Mpa.

Due to its good crushing effect, this jaw crusher has become the first choice for ore crushing processing equipment, but everyone who has used the jaw crusher knows that this machine often appears a lot of dust during the crushing process and diffuses into the air. In China, it not only destroys the ecological environment, but also seriously endangers the health of the staff, so I will tell you the cause of the dust problem of the jaw crusher.

I. Cause analysis of jaw crusher dust

1.Dust point analysis of crusher

The jaw crusher produces dust mainly from the inlet, outlet and conveying system. The materials to be processed are crushed and crushed by a crusher, and then sent to the next process by a conveyor. In the process, a large amount of dust will be generated, and the concentration is very high. The dust source will be diffused to the surrounding area by the airflow. Causes severe dust pollution.

2.Cause of dust generation at the inlet

The jaw crusher is not a fully enclosed device. During the feeding process, dust overflow will inevitably occur, which causes a relatively high concentration of dust to be generated around the feeding port.

3.Dust production reasons

The crushed stone needs to enter the conveyor through the discharge port. Due to a certain gap between the feed port and the discharge port, a part of the stone will flow into the air. At the same time, the stone powder will also be in the process of the conveyor. Then it rises and spreads around.
