Spiral Classifier
Spiral classifier introduction:
Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball
mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-
dressing, and de-sliming and dehydrating in washing. Advantages are simple structure
, reliable working condition and convenient operation.
mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-

, reliable working condition and convenient operation.
Spiral classifier working principle:
According to the principle that different grains are with different specific gravity and
sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks
in the bottom. The classifier that has machine grading by discharging from the top can
filtrate the materials and send coarse materials to the feeding mouth and discharge the
fine material from the pipe. The seat of the machine adopts channel steel and body
adopts armor plate and the spiral axle adopts wrought iron, so it’ s durable. The lifting
equipments have two types, by electricity and hand.
