Ore flotation machine for colored black metal selection, can also be used for non-metallic, such as: coal fluorite, talc sorting. The flotation machine is driven by the motor triangle generation of drive rotation of the impeller centrifugal effect to form a negative pressure to inhale sufficient air mixed with the pulp on the one hand, on the one hand, stirring the mixture of pulp and drugs, while refinement of foam, mineral adhesive foam on top of the formation of mineralized bubbles float to the pulp surface. Adjust the ram height of the control surface, useful foam scraped by the scraper. Flotation machine because of their uniqueness, widely used in the course to pay attention to its optimization, in order to better play its role.
A. The flotation machine optimization method
As many as dozens of the flotation machine at home and abroad, its classification is also inconsistent, ore flotation machine according to the different works are divided into: a mechanical flotation machine, and inflatable flotation machine, mixed flotation machine or pneumatic mixing flotation machine, gas precipitate flotation machine.
Regardless of what kind of flotation machine, its efficiency should be considered in the production side Co., according to customer feedback and their own experience summed up to improve the efficiency of the flotation machine. Through the optimization of the main factors to affect the flotation machine inflatable can to some extent, improve the efficiency of the flotation machine:
Impeller and cover the gap: gap, inflation decreases, but the gap is too small will cause the impeller and cover the impact and friction, and inflation fell. More appropriate for the gap of 5 to 8 mm.
2 the number of revolutions of the impeller: within a certain range, the impeller speed is large, the inflated amount, but the speed is too fast impeller wear, power consumption, the slurry surface instability. In addition, some crisp ore is easy to produce mud phenomenon.
3 into the plasma volume: when the slurry into the impeller center is the most appropriate,the inflated amount. However, into paddle excessive, when more than the production capacity of the impeller, the pulp will plug the air tube, breathing difficulties, inflatable decline. In addition, the circulation of the slurry of internal volume (ie, return from the loophole on the cover to the pulp of the impeller cavity volume), the inflatable volume.However, the power consumption increases.
Static pressure impeller upper part of the slurry concentration: its value the greater the role in the impeller, the impeller rotation resistance increased small inflatable quantitative.
