High weir type spiral classifier classfying equipment

  High weir type spiral classifier classfying equipment:

Spiral classifier application:

The spiral classifier  Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry.

Production capacity : 10~1785 t/d

  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

Spiral classifier features:

The ruturn sand end add ruturn sand automatic lifting device,so can cancel the ball mill big spoon head device

One ton of ore can save electric 1-1.5degree

Avoid big spoon heag maintenance.

Slow down the unbalance impact to the ball mill big bear and pinion gear .

Spiral classifier working principle:

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, flow to the overflow weir and flow out.and the coarse particles sinks to the bottom of tank, transport by the spirals to the discharging mouth as return sand .Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.

High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also applied in de-mudding and dewatering.
