Description
Spiral classifier is one of the equipment for mineral processing. Spiral classifier with the help of solid particles of different specific gravity, and therefore in the liquid precipitation rate of different principles, mechanical classification of a device. Can be ground out of the mill in the material powder level in the filter, and then the coarse material using the spiral piece of rotary vane spinning into the mill inlet, the filtered fine material from the overflow pipe discharge. Spiral classifier is referred to as classifier. Classifier mainly has high weir type single screw and double screw, sinking type single screw and double screw four kinds of classifier. The classifier is mainly composed of transmission device, spiral body, trough body, lifting mechanism, lower support (shaft tile) and discharge valve. Spiral classifier is widely used in mineral processing plant and ball mill with a closed loop program shunt shunt ore sand, or used in gravity separation plant to classify ore sand and fine mud, and metal beneficiation process for particle size classification of slurry, and washing operations such as desliming, dewatering and other operations.
