Spiral classfier is widely used in classfying the mine slurry in the process of choosing metal,and can also used in desliming washing, dehydration, and often makes up the closed procedue with ball mill.

Classifier introduction:

There are four types classifier: high-grading single-screw and double-screw, sinking type single-screw and double-screw classifier.

Applicable scope:

Classifier is widely used in mineral processing plant to match with the ball mill and form a closed-circuit circulation to process mining sand. or used in gravity mine-selection plant for classifying sand and mine mud, and grading sand according to the particle size, disliming, dewatering in the mine washing process. This machine has simple structure, reliable operation, convenient operation, etc. the classifier is a kind of classifying machine that adopts the principle of settling speed difference according to different material sizes and specific gravity. fine particles floating in the water overflow out ;the coarse ore grain sinks to the bottom of the chase which will be pulled to the upper by the spiral and discharging out.

Structure features:

The classifying machine is mainly composed of the transmission device, the helicoid, tub,lifting mechanism and lower bearings(bearings) and mineral composition valve.
