    Depending on the flotation cell type, shear forces are applied by a variety of mechanical systems. Among the most common are impellers and mixers. Some systems combine the functionalities of these components by placing them at key locations where they can take part in multiple froth flotation mechanisms. Cleaning cells also take advantage of gravitational forces to improve separation efficiency.

  • Precise Air Flow Measurement Improves Flotation Cell

    Flotation cells are “aerated” with compressors or blowers and often with very little pipe straight run, which can affect the accuracy and consistency of flow meter readings. Larger processing plants also utilize modern process control systems (DCS, PLC) to optimize their operations, and the flow meters must be able to communicate with them. In this case, the flotation cells utilized 3-, 4
