Centrifugal concentrators have the following advantages over planar chutes:
(1) The
centrifugal concentrator is effective for the treatment of fine slime, and the recovery rate of the grain size of 37
to 19 μm
is as high as about 90%
. Because the separation of the ore particles in the centrifugal concentrator is a combination of centrifugal force and lateral flow membrane, the enrichment ratio is higher than that of the plane gravity chute; (2)
the re-election is strengthened because the centrifugal concentrator utilizes the centrifugal force. The process shortens the sorting time. Therefore, its processing capacity is large, about 10
times that of the automatic chute ; (3)
small footprint and high degree of automation. The main disadvantages are: 1
water consumption is larger than plane chute; 2 the
drum wall slope can not be adjusted, the production process is intermittent operation, and can not be continuously fed. Centrifugal concentrator in our country has become one of the main equipment of tungsten, tin sludge re-election in recent years and try to lean ore beneficiation of iron. The centrifugal concentrator is still being improved and improved continuously. While improving the sorting index of the beneficiation equipment, it focuses on the development of large-scale and continuous.
