Spiral Classifier
Introduction
Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry.
Capacity
10～1785 t/d
Product improvement
An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.
♦ Product Application
The overflow spiral blade is higher than overflow level, and the overflow spiral center is lower than overflow surface. The spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm
♦ 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, and the coarse particles sinks to the bottom of tank. Overflow dam is above the bearing center which is under screw shaft, and is underneath overflow end.
Spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also applied in de-mudding and dewatering.
