In the process of mine mining, due to transportation, transmission etc. such as crushing and movement of quarry,  fine-sized particles will gradually separated, which will produce more and more dust. The more types of dust in the air,the more difficult settling with the air.If we breath such air into our respiratory tract, it will be harmful to our health.The state encourages and supports scientific and technological research of mine dust prevention, extends the use of advanced technology of mine dust prevention and control of atmospheric pollution, mine dust catcher technology can effectively control the harm of mine dust.It adopts filtering material to filter dust, keeps the dust left on the filter material, so as to dedusting the air.
