The function of air dust and to dilution and discharge of dust in the air within on mine.Many enhanced my experience has shown that in the adoption of comprehensive dustproof actions, improve and enhance ventilation function, the efficient use of cooling down force, well the impact crusher of dust-proof is important and ring. In the process of open-pit mine transportation vehicles flying dust is the main dust source open field. Transportation dustproof action primarily have: before loading for the study of the water supply and discharge of mine in a sprayer;Strengthen road surfaces conservation, reduces traffic transport process of the ore;The major transport routes to use representative concrete sidewalk and; Developed mechanical road transport frequently with spray, and add to water of wetting enhancing the dust impact.Still can’t use sprays sandstorm develops antibacterial, inhibition, the major components of powder agent to absorb the moisture agents and plastic bonding, already can’t absorb water and dust forming, but also can enhance the quality of road surface. Due to the variety of materials, in the use of it can break damp gender matter, but when crusher and the impact crusher of the structure and characteristics fully, in a material medium is damaged, the cone crusher compared with other crusher has unique benefits, large sunken, effects of crushing, smooth connections, ensure that the moisture content of the material under high, can still be working smoothly.But by the impact crusher crushing cavities are small, so damaged wet impact crusher equipment of the most appropriate.
