the case of naturally aspirated machines Wemco , it is referred to as Hybrid Energy Flotation and incorporates at least three phases: Standard flotation machines standard energy input, rotor speed r/min , rotor size/type at the beginning of the row, where flotation is typically froth-phase limited
The SmartCell Flotation series combines the proven Wemco mechanism with cylindrical cells to optimize energy input, aeration, and mixing. This configuration reduces pulp turbulence and improves froth stability. Additional standard features include a hybrid draft tube, beveled cell bottom, froth crowder, mixing baffles, and radial launders.
Flotation Machine Working Principle. When the impeller rotates, eddy current is generated in the vertical cylinder and the draft tube. The eddy current forms a negative pressure, and the air is sucked from the intake pipe and sucked in the impeller and stator regions and through the draft tube. Mix the pulp.
Streamlined hybrid draft tube to optimize slurry pumping Beveled tank bottom to eliminate stagnant zones and improve particle suspension Tank Baffles to stabilize froth surface and enhance mixing Radial Launders to improve froth removal and increase recoveries The Wemco SmartCell Flotation machine is available is sizes up to
The new design is called the hybrid draft tube, recognizing its combination of features from the 1 1machines and the original SmartCellprototype. It has a conical inlet which merges to a cylindrical section.
A centrally lo ed paddle-wheel type impeller generates a rotating pulp vortex which extends between two stationary elements: the sand-pipe lo ed at the top of the cell, and the draft tube lo ed at the bottom of the cell.
Unique Flotation Mechanism At the heart of each 1 1 cell is a patented rotor-disperser that delivers intense mixing and aeration. Ambient air is drawn into the cell uniformly distributed throughout the pulp, providing optimum air/ particle contact.
When the JJF mechanical agitation flotation machine is working, vortexes are generated in the vertical tube and the draft tube. This vortex forms a negative pressure and sucks the air from the air inlet pipe. It is in the impeller and stator area with the slurry sucked in through the draft tube. mixing.
