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

The dense medium cyclone – past, present and future ...

Jan 15, 2018  The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small footprint.

DENSE MEDIUM CYCLONE OPTIMIZATON (Technical Report)

A mathematical model is proposed to describe the multiphase flow in a dense-medium cyclone (DMC). In this model, the volume of fluid multiphase model is first used to determine the shape and position of the air core, and then the mixture multiphase model is employed to describe the flow of the dense medium (comprising finely ground magnetite in water) and the air core, where the turbulence is ...

In the dense medium cyclone separation of coal, the overflow to underflow (O/U) flowrate ratio has not been considered as a major parameter in correlation with the cyclone performance, since it is not directly adjustable. It is a common practice in the optimization of cyclone performance, however, to stipulate the range of cyclone orifice diameter ratios in respect to the cyclone diameter and ...
