The working principle of mine dust collectors is mainly based on the filtration principle, which intercepts the dust particles in the dusty gas through the filtering effect of the bag, thereby achieving the goal of purifying the gas. Mining dust collector. The mine dust collector also adopts a comprehensive effect of gravity, inertia force, collision, and screening for dust removal and filtration. These different dust removal principles and cleaning methods can be selected and applied according to actual situations. Mine dust collector is suitable for various metal ore beneficiation, crushing and screening, belt conveyor operation, crushing and screening in stone plants, and other occasions.
