With the development of mining industry, investors present various requirements of the features of flotation machine. Now there are many kinds of flotation machines, such as agitator flotation machine, pneumatic flotation machine and pneumatic- agitator flotation machine. And different mineral ores have different hydrophilicity, so the final configurations greatly depend on the professional designs.
Hammer crusher designed by SBM fits for producing 0-3MM coarse powder products. This machine adopts theories of traditional crushing machines and grinding mills. It makes up the shortage of common mills, and it is the best choice to produce coarse powder at big capacity.
Compared with the commonly screening and grading equipments, the High-frequency screen adopts higher frequency. As a result, it is able to damage tension force of the pulp surface. Also the fine particles are able to oscillate speedily on the surface of the screen because of the high frequency, and the big expecting minerals are isolated from the pulp easily.
