Spiral Classifier
Speed of screw (r/min) : 2.5-8
Overflow capacity (t/d) : 10-1785
Introduction
Product profile
A rotating spiral is used to divide a mixture of different thicknesses into different grain-size levels in the fractionating slot.
A rotating spiral is used to divide a mixture of different thicknesses into different grain-size levels in the fractionating slot.
working principle
The slurry is fed into the U-shaped groove from the feed inlet in the middle of the side of the channel. With the low speed rotation of the screw and continuous stirring of the slurry, most light and fine particles are suspended on the top, and overflow from the overflow Weir becomes the overflow product. Coarse and heavy particles will settle at the bottom of the trough (sand sink, pushed by the spiral blade above the chute and discharged, and dehydrated simultaneously during the transportation process. If the sand sinking through the chute into the grinding machine regrinding, the sand into the grinding machine is sand return.

Advantage
Simple structure, stable and reliable working ability, easy to operate, low in water content for sand return and easy to return sand with grinding machine. It is often used for pre-grading, checking and controlling classification of wet grinding proccessing, and a few equipments are used for dehydration and desliming.
