The impeller-stator system is the most critical component of a mechanical flotation cell as it serves the main functions (solid suspension, gas dispersion, and bubble-particle interactions) and is largely responsible for the overall performance of the cells. The flow patterns within the cell largely depend on the impeller-stator systems.
Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.
