Spiral Classifier

The spiral classifier is one of the equipment in mineral beneficiation plant. The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in the liquid is different. The coarse material is screwed into the feed port of the mill using a spiral blade, and the filtered fine material is discharged from the overflow pipe. There are four types of classifiers: high weir type single screw and double screw, submerged single screw and double screw. The classifier is mainly composed of transmission device, spiral body, trough, lifting mechanism, lower support (bearing) and discharge valve.

Spiral Classifier Advantages:
1、Simple structure, easy to maintain
2、Easy operation and stable performance
3、Gravity connection with Ball mills; slurry pump conveying is not necessary.
4、Large volume with buffering and conveying effect, better for grinding work.
