Our original Cavex® classifying cyclone set new industry benchmarks when introduced in 1996, over 20 years ago.. Its laminar spiral inlet geometry design, containing corner-less full-circle 3D curvature, is renowned for reducing turbulence inside the hydrocyclone, whilst increasing capacity, efficiency and wear life.. Compared to other separating equipment, the Cavex® CVX hydrocyclone has:
Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder.
Applications. The Cavex®2 high-efficiency cyclone is designed for heavy-duty industrial and abrasive applications where above-average wear rates are present, requiring frequent replacement of liners.. These classification cyclones are renowned for their performance in separating solids and slurry thickening processes with a wide range of feed materials (e.g. desliming, dewatering and solids ...

The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one Cavex 2 650 in a six-place cluster of existing Cavex cyclones and saw an improvement of up to 48.5% in circulating load and 31.7% in water bypass versus the original cluster, according to Weir Minerals.
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine ...

Weir's Cavex hydrocyclones expand footprint across Africa. Weir Minerals Africa has expanded its Cavex hydrocyclone footprint across Africa with its most two recent orders going into the Central African Copperbelt; one in Zambia and one in the Democratic Republic of Congo (DRC) Cavex 650CVX hydrocyclones installed on a ball mill cyclone cluster.
In addition to the increased wear life of the Cavex® hydrocyclones, the mine was able to achieve a major reduction of the >300 micron particles from the overflow. Once the cluster was modified so all cyclones were Cavex® hydrocyclones (in addition to some plant modifications) the mine increased gold recovery. Cavex® hydrocyclones in mining

Hydrocyclones Mclanahan. Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.This is typically done in the form of an ultra fines recovery system comprised of a sump, pump, cyclones and dewatering screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and stackable form.
