Spiral classifier also can be called spiral separator, screw classifier or screw separator.
Model: FG500,2FC-3000
Overflow Quantity: 32-1785t/24h
Material: Iron Ore Beneficiation
Spiral classifiers can grade different particles in ore slurry during the metal beneficiation process as well as deslime and dehydrate in the washing operation.
They are widely used to separate ore sands by forming a closed-circuit with the ball mill in concentrators, or in gravity concentrators to classify ores and fine muds.
The long and narrow tank is helpful to achieve an ideal stirring effect and extend the suspension time of the material in the water.
A sufficiently large settlement area prolongs the suspension time of materials and is more conducive to material classification.
The proper slurry pool depth, area and spiral structure achieve good control of the classification strength.
An automatic lifting device for returning sand is added to the sand returning end, and the configuration of the large spoon head of the ball mill is canceled.
Frequency conversion control technology makes the operation more convenient.
