Floatation column is the mineral separation device with a kind of function and floatation similar machine, this equipment at last centuries 60 time are published, once extremely red temporarily. What does SBM machine tell the unusual phenomenon that explains floatation column to see in use process middling to have for everybody today? How should we prevent this kind of phenomenon to appear again?
Floatation column is the cylinder of rice of a tall 6~7, bottom contains a group of bleb generator that make by cellular plastics, upside sets mine alloter. The ore pulp that gives distributings equably to go up in cylinder cross section, slow drop, in drop bead of the mine in the process and ascendant bleb are interlinked.
The height of area of the floatation in floatation column is more than floatation machine far, mine bead and bleb collision and adhesion probability are big. The onflow intensity of air current of the oar inside floatation area is inferior, conglutinate falls off not easily in the hydrophoby mine bead on bleb. The bubble layer ply of floatation column can be amounted to tens of centimeter, action of 2 rich market is particularly remarkable, and can drench to bubble layer water is planted with strengthening this action. Often thick anthology can obtain final concentrate.
Run to make sure floatation column is regular, ask strict control gives mine quantity, wind force and leeway, whether does seasonable observation have following case to appear.
1, magic flower
The main reason of magic flower is empty tracheal burst and pressure of air giving a person too big, should adjust wind pressure right now, if still have magic flower, should jockey, check gas-filled tube whether burst or existence not impaction phenomenon, trouble removal is rear can drive.
2, gangue canal jams
This is the most incidental accident in producing unit process of cargo bandling, because the ore granuality in ore pulp is too thick,its reason majority is, quantity giving mine increases suddenly, gangue gate leaves too small or drop in column other and sundry etc.
The proposal solution that SBM machine gives out is, be in charge of in platoon mine beforehand most the proper place of the lower end installs high-pressured conduit or high-pressured wind is in charge of, once happen,jam, water of usable high pressure or high-pressured wind come dredge. At the same time the examination gives mine size with quantity giving mine, adjust till it is normal to come.
3, bubble is little
Its are main the reason is empty tolerance is not worth or drug system has a problem, answer to undertake in time adjustment.
Floatation column already had 20 old histories in the application of our country. Nevertheless, SBM machine discovers, the application of floatation column is not at present common in mineral separation industry. And the main obstacle that aerator jams is promotion of influence floatation column; Operation of floatation of mine of much metal vulcanization often has in alkalescent medium, small hole aerator writtens guarantee dirty is the breakdown that often appears. These two reasons affected the floatation column promotion in mineral separation bound and application greatly, nevertheless, SBM machine thinks, if can try to improve in technical respect to floatation column, its develop prospect still is very considerable.
