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 material and powder ground out of the mill can be filtered, and then 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. We have submerged spiral classifier and high weir spiral classifier.
