screw classfier 

 application : this spiral classifier is widely used with a ball mill to classify mineral sands.or classify ore sand and fine silt in gravity mill .it is also applied to classifying granularities in mineral separation ,or desliming and dewatering in ore washing .

 feature : spiral classifier is a kind of classifying machine that classifies big and small mineral granules ,it works according to the fact that different granules (with various sizes and weight ) sink at different speeds in liquids ,It can filter powders grinded from mill and rotate the coarse materials to the feeding hole of the mill and discharge filtered fine materials though the overflow pipe . the chassis of this spiral classifier is made of channel steel and the main machine is welded by armor plate . the water inlet and the shaft head come with cast iron sleeves ,which are robust and abrasion resistant . both manual-operated and automatic hoisting devices are avaliable .
