  • Large Diameter DM Cyclone Operating Data - ACARP Abstract

    The use of large diameter (greater than 1 m) dense medium cyclones has become widespread in the Australian coal industry, and in the future is likely to be the dominant processing unit. There is little . for a given cyclone diameter, there is a particle size, termed the 'breakaway size', below which Ep deteriorates rapidly.

  • Dense Medium Separation - An Effective and Robust Pre .

    Firstly, below a minimum size (e.g., 0.3 to 1.0 mm), the dense medium separation efficiency decreases to an unacceptable level, affecting recovery. This is referred to as the breakaway size. The breakaway size of a cyclone is related to its diameter, where larger cyclones have a larger effective lower treatment size. Secondly.
