The jaw crusher will generate dust during the work, and the dust is very harmful. It will not pollute the environment of the entire surrounding area and cause harm to the health of the mine production staff, but also accelerate the wear of the jaw crusher and shorten the jaw crusher. service life of the crusher. Therefore, dust removal has become a problem that many mining enterprise owners are more concerned about. We know that the jaw crusher dust removal is a very important and necessary daily task in the mine production and operation process. Then, how to reduce the dust during the working process of the jaw crusher? After years of practice and research in mine production, Jiaozuo Zhongxin Heavy Industry staff can use the following methods to solve the dust pollution of jaw crusher in the process of mine crushing production. We dedust the jaw crusher and vibrating screen with a large amount of dust, and add a dust removal device, which can reduce the external dust emission of the jaw crusher during the crushing process, and can also reduce the generation of noise. Secondly, on conditional mine construction sites, we can reduce mine dust emissions by using wet sand making and crushing technologies. Through the above two methods, it is possible to reduce the dust emission during the crushing process of the jaw crusher.
