This classifiers suitable for dewatering, medium, drainage ad spraying in ore dressing for medium and fine material wet and
Dry classifying in mine.
Finely ground ore from the feed in the settlement area of central mouth into the tank, inclined bottom sink installation is pulp grade subsidence area, screw rotation speed, mixing effect on pulp, making light of fine particles suspended above, flow to the overflow side weir overflow, into the next process processing, coarse particles settling to the bottom, the spiral conveying to the discharge opening as return sand discharge. Usually spiral classifier and grinding circuit, will return to the mill grinding grit.
Spiral Classifier
Spiral Classifier introduction:
There are four types classifier: High-grading single-screw and double-screw, sinking type single-screw and double-screw classifier. The classifiers are suitable for dewatering, medium, drainage ad spraying in ore dressing for medium and fine material wet and dry classifying in mine.
Applicable scope:
Classifier 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 adopt 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 classifier is mainly composed of the transmission device, the helicoid, tub, lifting mechanism and lower bearings (bearings) and mineral composition valve.
