Spiral classifier is one of mineral processing equipment, spiral classifier with different proportion of solid particles, thus in the liquid precipitation rate of different principle, mechanical classification of a device. spiral separator Can grinding mill in the powder level in the filter, and then the coarse material using spiral rotary vane screwing in mill inlet, to filter out the fine material discharge from the overflow pipe. Spiral classifier classifier for short.Classifier is mainly has high weir type single spiral and double spiral, submerged four single spiral and double spiral classifier. Hongxing machienry in the production of series of classifier is widely used in ball mill in the
