Mechanical stirring. Novel and unique way of feeding the pulp. Reasonable pulp flow large capacity.Aeration efficiency is high, the adjustable range is wide, flotation speed. Boot condition, can adjust air inflow at will.Mixing bodies with curved blades for the impeller and the steady flow radial board will enable the coal slurry circulation and moderate inflation.For coal, grain size, concentration, and optimize the design parameters of fluid dynamics, high-density and thick, fine-grained coal has also been the effect of the ideal separation.
