Knelson continuous variable discharge concentrator(CVD) is also called horizontal auto discharge centrifuge or CVD concentrator is one famous gold separating machine design and upgrade from Knelson gold concentrator and hot selling in china.

Models of stl40 stl60 stl80 stl120 are widly used in alluvial sand gold mine,it's also a good performacne in separating natural gold in rockmine and tailings after separating of mineral.The  advantage is it works well and good performance in jolting surroundings such as dredging boat,movable gold separating car etc.

Working principle

Knelson continuous variable discharge concentrator(CVD) stl40 stl60 stl80 stl120 the separating principle is same with vertical type centrifuge.It is enhanced gravity centrifugal gold equipment based on the principle. In the high times enhanced gravity field, gravity difference proportion and the proportion of small mineral is greatly enlarged, which makes the separation of heavy minerals are more easily than the natural gravity field; and the material bed special design of retaining structure, the flow of water patented technologies and interaction of interference settling down, can continue to maintain a loose state. Under the above conditions, heavy mineral particles can replace the light mineral particles occupy in the sorting bed position and retained, light mineral particles as tailings are discharged, so as to realize the mineral particles by gravity separation.

Knelson continuous variable discharge concentrator(CVD) in the product operation, the acceleration of gravity acceleration up to 60 times the enrichment cone or higher, when the pulp into the enrichment cone bottom, effect of slurry under the centrifugal force was thrown to the inner wall of the cone enrichment, and along the inner wall of the upward movement, at the same time by the water inlet hole cone continuous enrichment to make the bed in the cone of injection flow fluidization. In the action of centrifugal force and hydraulic recoil under radial resistance of single gold and other heavy mineral particles can overcome water, centrifugal sedimentation or drilling gap settlement in the bed. While the gangue mineral concentrate because of the less affected by centrifugal force, hydraulic recoil effect hard to overcome the axial force in the axial flow force and centrifugal force Together to promote the discharge of enrichment cone into tailings.

Features of continuous variable discharge gravity centrifugal gold separating concentrator

1.High running ration

3.PLC control one preson can operate

2.Less electricity cost,long work life and little maintance

4.Auto discharge technology and no need to stop the machine to get concentrate
