A reduction of rotor tip speed on higher speed was shown to have a smaller effect on flotation cell performance compared to a similar extent of reduction with lower rotor tip speed. Lastly, the results were scaled into industrial scale and the profitability of the speed reduction was evaluated

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell

Unique flotation mechanism. At the heart of each Wemco 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

in place of the conventional rotor-stator mechanism historically used by mechanical flotation cells. instead of operating with a large volume tank, the Stackcell™ forces the bubbles and particles to contact within a very small confined area within an aeration chamber. Under this highly turbulent environment, the flotation

The WEMCO rotor is located at top of the cell, and the nextSTEP rotor is placed at the bottom of the machine. The rotor placement creates different flow patterns within the cell, which affects froth recovery. When it comes to aeration of the cells, WEMCO machines draw in

FLSmidth launched its new nextSTEP TM rotor/stator technology during the annual Society for Mining, Metallurgy & Exploration (SME) conference in Denver/USA. Used in forced-air flotation equipment, the patent-pending design of the nextSTEP TM rotor/stator provides a “step change” in flotation metallurgical performance and energy efficiency (Fig.). .). The nextSTEP TM rotor/stator has a very

The existing mechanism assembly is utilised. Rotor and stator are attached with adaptor flange and baseplate respectively, and drive sheaves replaced to optimise speed. The FLSmidth conversion process is thorough and proven – with a large number of successful retrofits already for flotation cells ranging in size for 1.7m3 to 250m3

Experimental data confirms that use of a froth crowder device as disclosed expedites movement of the froth toward the launder for more efficient operation, permits operating the rotor of the flotation cell at reduced speeds without compromising the efficiency of operation, and reduces the amount of air necessary to produce a froth in the cell

Aug 01, 2018 After the implementation of the optimised rotor speed (55 Hz) as standard operating practice, the final tail grade of the associated conventional flotation circuit was observed to stabilise at a lower value, decreasing from an average of 0.20 g/t when the flash flotation cell was operated at 50 Hz to a lower average of 0.18 g/t when the flash

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator
