Description
FG spiral classifier is the most commonly used classifying equipment nowadays.It classifies the minerals by taking advantage of the different settling velocity of mineral particles with different size,shape,and density.The spiral classifier is mainly applied in the grinding circuit as pre-classification and check classification.It could also be used in ore washing,de-mudding,and dewatering.
There are several types available:
Single spiral,double spiral type
High weir,Immersed type
Standard type,Extended type
Structure
Working Principle
The grinded pulp is fed into tank from the inlet in the middle of settlement region,and the slurry classification sedimentation area is under the inclined tank.The spiral with low speed rotation stirs the slurry,so that the fine particles rise and overflow,while the coarse particles sink to the bottom of tank and are pushed upward by the spiral.
