How the Flexicone concentrator works

Flexible cone is pressed from sides with rollers , are the characteristic feature of centrifugal concentrator with mineral floating bed CCFB. As a result, the cone in cross section acquires shape of rounded triangle, square etc (depending on the number of pressing rollers).


During rotation, points of mineral bed are moving with periodic approach and removal from rotation axis as though they are floating in centrifugal field. Radius of cone inner surface curvature is changing with interval of dozens of hertz from minimum to big. And as a result centrifugal field is changing from zero to maximum, exceeding centrifugal force of round cone up to 1.5 times.

Minerals inside grooves at bending of cone are subject to frequent movements in direction of axis. When mineral bed is compressed, material pressed out from grooves and when non-compressed, material moves deeper in centrifugal field , thus performing movements similar to those of jigging machine.


Due to characteristic features of cone wall construction, during its rotation in compressed condition, mineral layers move with regard to each other , and these vibrations similar to processes on concentration tables .


Consequently, the minerals in centrifugal concentrator is subject to complex motions similar with motions on jigging machine and vibration table, but it all takes place in centrifugal field with variable value, whereas intensity of this value ranges from values close to zero to values in the first hundreds of G. This motions support mineral bed in loosened fluidized state, when grains of various density, depending on their size, are quickly differentiated in depth of the groove: grains of high density fall down on the bottom, and the light ones float to surface of grooves, where they are washed out by pulp flow.

In addition, in our latest development, an easily installed magnetic system for removing the magnetic fraction also allows you to enhance the process of thinning the mineral bed due to the presence of a magnetic fraction in the pulp.
