Dedusting equipment is the use of dust water and compressed air pipeline underground, the pressure in the water, add some additives, through special equipment, complete suction - mixing - foaming process flow, bubble, through the distributor, nozzle bracket assembly to spray on the dust source. Foam to dust by covering, wet, good adhesion, effectively reduce the dust concentration of mining surface, greatly improve the working environment of working face, improve the underground work personnel's working efficiency, reduce the mining front-line workers pneumoconiosis incidence.

Compared with other wet dust suppression methods, the dust suppression can reduce the water consumption by 50% to 80%, and the dust suppression efficiency is increased by 3~5 times than that by spray irrigation.
