Dense medium cyclone operating pressure is normally expressed in meters of head as a function of the cyclone diameter. For example, a cyclone of 500 mm diameter operating at a head of 9D will have an operating head of 4.5 m (9 x 0.5). The data in the following sections is for a tangential inlet design with square opening.
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.

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …
