high quality Spiral Classifier Mining Equipment Spiral Classifier
Spiral Classifier
This spiral classifier can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically.
A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has a inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the agitation of the water hinder the fines from settling to the bottom, but the coarser particles do settle and are carried up the slope by the revolving spiral, to the discharge, located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage in the process, the fines overflow from the pool area. The pool area normally has an adjustable wier, which will determine the amount of time material is in the pool area, and subsequently the coarseness of the discharge from the pool area, with a shorter residence time the coarser the discharge, along with the fines. Therefore, some control of the classification size can be accomplished by adjusting the weir height up or down, to give more of less residence time in the pool area.
