Product Description
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. The seat of the machine adopts channel steel
and body adopts armor plate and the spiral axle adopts cast iron,
so it's 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

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. 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.
