Introduction of spiral classifier:
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.There is 1 or 2 vertical axles installed in the chute, spiral blades are installed along the axle one after another.
Types of spiral classifier:
According to the height of the surface of the liquid classification, the machines can be divided into high weir type and immersed weir type.
Technical parameters of spiral classifier:
