WebConversely for medium particles below a limiting size, performance is relatively unaffected and the geometry of the lower part of the cyclone becomes less important. Dense-medium cyclones are available in several sizes with diameters of 0.5–1.0 m being common in the coal industry. The 0.5 m cyclones have a capacity of about 50 t/h of raw coal. WebOur Cavex® dense-medium cyclone features the innovative laminar spiral inlet geometry design of the original Cavex® hydrocyclone range, but it is cast in strong chrome white iron. This enables the hydrocyclone to outperform in corrosive applications requiring heavy-media separation such as potash, coal, diamonds and hard rock. WebThe three-product cyclone consists of a cylindrical dense medium vessel, similar to a Larcoderms, with a conventional dense medium cyclone attached to the rejects outlet of the primary unit. The cyclones can be pump fed or gravity fed -Figures 3 and 4 show a gravity-fed and pump-fed cyclone respectively. bing online download
