The overflow spiral blade is higher than overflow level, and the overflow spiral center is lower than overflow surface;
The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm

High spiral classifier operation: the grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.
