Spiral Classifier

such machine is mainly used in the production flow of metal processing. according to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 14-325 meshes are classified. waste mud or water for ore sand can be separated from the ores.
such machines are divided into single spiral classifiers and double spiral classifiers. beside, they are also divided into high weir spiral classifiers and submerged spiral classifiers. if the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of spiral at the overflow end, the spiral classifiers are high weir ones. if the overflow edge is higher than the center line of spiral shaft and also higher than the external diameter of spiral at the overflow end, the spiral classifiers are submerged ones. high weir classifiers are usually used for the classification with particle size of below 100 meshes. submerged classifiers are usually used for the classification with particle size of below 200 meshes.
