Webfactor. It is well established that the rheological characteristics of the dense medium have significant effect on DMS cyclone performance2. Typical tests that are carried out to elucidate the medium characteristics include in-circuit medium density, ferrosilicon size frequency distribution, cyclone overflow and underflow density as 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.
