Heavy Media Separation Process (ferrosilicon) | DMS Powders

The medium density determines to a large extent the density at which the separation will take place, and is the main variable available to the operator for controlling separation In static bath separators, such as drums and cones, the separating density (or cutpoint) is generally close to the medium density In dynamic separators, such as cyclones and triflows, the separating density is

Dense Media Separation (DMS) Plants JXSC Machine

Following the Archimedes principle – particles smaller than the density of the heavy medium will float, and particles larger than the density of the heavy medium will sink in the medium The fluid movement and particle sedimentation are no longer the main factors contributing to the layering, and the property of the medium itself is an important factor in the separation Heavy medium

Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter This prevents finer filtration methods from having to deal with large, more abrasive
