Introduction for Classifier and Spiral classifier
There are four types of classifiers, high weir type single and double spiral classifier, immersed single and double spiral classifier.
Spiral classifier (Screw classifier) is widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and desliming and dehydrating in the washing. Advantages are simple structure, reliable working condition and convenient operation. 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 cast iron, so it’s durable. The lifting equipment has two types, by electricity and hand.
Spiral classifiers are suitable for
a.Separation of fine particles and liquid from coarse particles
b.Separation of light particles from heavy particles
c.Separation of the particles into a number of products graded according to size
d.Separation of liquid from solid particles
Main features of Spiral Classifiers
1.Adjustable weirs
2.Sealed, submerged bearing
3.Optional automatic lubrication system
4.Rigid tank and substructure
5.Wide choice of tank design
6.Overflow collection box
7.Wide range of industries serviced
