The design and Performance of Dense Medium
1. **Separator Geometry:** The design of DMS separators is influenced by the rheological properties of the dense medium, particularly its viscosity and particle size distribution. The geometry of the separator, including the size and shape of vessels, cones, or cyclones, is tailored to accommodate the flow characteristics of the medium.

The dense medium cyclone – past, present and future
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 Separation Equipment | SpringerLink
Dense medium separator is a static separation equipment, while dense medium oscillating chute and dense medium cyclone are dynamic separation equipment. In static separation equipment, the separation medium moves slowly, and it is a stable fine particle suspension liquid whose density is close to that of the mineral particles subject to separation.
