Pneumatic Ejector Flotation Machines
Pneumatic ejector flotation machines are designed for enrichment of mineral deposits at the rougher, scavenger and cleaner flotation and provide following advantages:
- high technical efficiency due to process selectivity and high foam density;
- reduction of energy consumption;
- low capital and operating costs;
- possibility of process automation.
Reduced power consumption in comparison with mechanic flotation machines is provided by the absence of moving parts and as a consequence engines. The use of non-metal structural components also ensures low capital and operational expenditures.
Pneumatic ejector flotation machines automatically sustain a specified height of the foamed layer, which ensures a higher quality of the ready product.
An important feature of ejector flotation machine is flotation process high intensity, that is given by:
- the usage of aerator ejector, that gives high pulp aeration stage both in degree of the amount of sucked in air and in the degree of air bubbles dispersion;
- significant and sudden pressure differential in the ejector aerator (from3 atm to 0 atm)
- smooth movement of aerated pulp from the bottom upwards which accelerates the floating of mineralized bubbles and increases the efficiency of the machine.
Thus by replacing mechanic flotation machines with pneumatic ejector ones a manufacturer increases the capacity of the production area, reduces losses of flotation tailings and raises the quality of the concentrate after the main and cleaning flotation.
Our company can design and manufacture pneumatic ejector flotation machines of different sizes according to the customer’s demand.
