Dense Medium Cyclone

From the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s. During this period, the “typical” dense medium cyclone circuit was designed to process raw coal
