Introduction of mining spiral classifier in concentrating plant
Spiral classifier, working with ore mills to form close circulation in the concentrating plant, whose classification process depends on the sedimentation velocity of the particles. Its external appearance is a rectangular oblique chute, whose bottom is semi-circular; the inclination angle of the bottom of the chute is from 120 to 18.50.There is 1 or 2 vertical axles installed in the chute, spiral blades are installed along the axle one after another.
Working Principle of mining spiral classifier in concentrating plant
If there are two spiral axles in the chute, all of the spiral blades rotate outwards when the machine is viewed from the top. The slurry, fed from the flank of the chute, form classification of sedimentation at the bottom of the chute. Coarse particles dip into the bottom of the chute, and then they will be pushed to the top by the spiral and discharged. During the transportation process, the coarse particles dehydrate themselves. The fine particles, which do not have enough time to dip into the bottom of the chute, are carried by the ore pulp flow through the surface and discharged from the overflow weir.
