It is fed, is uniformly flowed into flotation column by top mineral-feeding pipe.Compressed air is the high pressure ring pipe through cylinder lower end by being vertically arranged
Air gun be filled in column, a large amount of tiny bubbles of formation are evenly distributed on entire section, and ore pulp is under the effect of gravity slowly
Decline, bubble slowly rise from lower to upper, constantly meet in column with the valuable mineral to be chosen in ore pulp.In convective motion
In due to medicament effect, the mineral to be chosen just are attached on the bubble surface of rise, form mineralising bubble on cylinder top
Foam layer is scraped by scraper plate or is spilt in concentrate slot certainly, remaining mineral (usually gangue or non-ore dressing object) is then from cylinder lower cone
The debris tube at bottom is discharged.
Ore pulp can be settled gradually flotation column after a shutdown, deposited in flotation column bottom, caused debris tube obstructed.Existing skill
Normal practice in art is that back-flushing device is equipped on debris tube, and booting when opens back-flushing, impacts debris tube and flotation
The coarse sand of column bottom siltation, convenient for dredging tailing pipeline.But back-flushing has following disadvantage, first is that recoil water pressure compared with
It is small, it is difficult to penetrate thick coarse sands layer, dredging tailing efficiency is lower；Second is that the water lines that recoil when winter temperature is lower are easy
Freeze, in this way booting when tailing dredging work do will be extremely difficult；Third is that a large amount of back-flushing enters meeting in flotation column
It causes pulp density after booting to reduce, will definitely increase collecting agent unit consumption, influences the production target in start process.
