RCS™ flotation solutions
Combining the benefits of circular cells with the unique features of the patented DV™mechanism, the RCS™ (Reactor Cell System) flotation technology has been developed to create ideal conditions to maximize flotation performance for all roughing, cleaning and scavenging duties. The cell can be modified to handle high density slurries.
Flotation technique: Its mechanisms and design parameters
In the Jameson cell slurry and air are introduced at the top which proceeds downward in the downcomer and forms a liquid jet. Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …

In mechanical cells there are two modes by which air is introduced into the cells; one is the forced air entry mode carried out using a blower and the other is the self-induced air entry mode, in which air is sucked into the cell by vortexing. The two cell designs can be distinguished by the difference in vertical loca-tion of the impeller in ...

Accurate level control for improved metallurgical performance Controlling pulp levels in flotation cells is a complex task with many different aspects, such as the effect of cell structure and valve sizing, to take into account. Control becomes more challenging as the number
Flotation cells for profitable minerals concentration
The basic module of the WEMCO 1+1 flotation system is a cell consisting of a single tank and mechanism. Several cells are bolted together to form a flotation machine with feed, connection and discharge boxes as required. Pulp level in the tanks is controlled by automatically operated dart valves in the connection and discharge boxes.
Productive froth flotation technology
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 and use air without the use of an external blower. They are also self-controlled and do not require constant monitoring from an operator or moderation of air control valves.

tapping from the existing air pipeline with an air control valve to control the air supply to the cell. The air enteres the cell through a rotary union arrangement at the top of the cell. It then passes through the hollow shaft and then to the new rotor–stator mechanism, which shears the air into small bubbles and disperses them across the cell.
Aeration Control on Self-induced Cells
First thing is flow measurement sensor needed and then a flow control valve, butterfly valve does ok. Just watch that the air flow signal will be quite noisy as the vortex rises and falls so use a fair amount of filtering. You will need to seal around the air intake with a box of some sort unless there is an air intake already built into mechanism.
