When flotation machine works, slurry is inhaled from the bottom of
the trough to the space between impellers. Meanwhile, the
low_pressure air send by fan is sent to this area through the air
distributor in the hollow shaft. After sufficient mixing, the
slurry is pushed out by the impeller, and then goes to the whole
trough. When the froth rises to the stable level, after the
enrichment processing, froth overflows to the froth trough from the
overflow weir. Another part of ore slurry flows to lower part of
impeller for the re_mis with air. The remained slurry flows to the
next trough until becomes residue.
