Product Description

Good performance coal washing machine or Spiral classifier or sand washer
with competitive price from Zhengzhou

 

Product Description

High spiral classifier operation: the grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.


>>> Sprial classifier application

Spiral classifier is widely used in ore dressing plant, gravity concentrator to grade ore and metal, and to carry out particle size classification of pulp, desliming and dewatering operations.
1.Suitable for distributing ore in concentrator with ball mill in closed-circuit circulation.
2.Suitable for grading ore and fine mud in gravity concentrator;
3.Particle size classification of slurry in metal ore dressing process;
4.Desilting and dewatering operations in ore washing operations.

>>> Sprial classifier working principle

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.
