Application

Spiral 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. FG series Spiral Classifier has simple structure, reliable operation, convenient operation,etc. The spiral 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.

Woring principle

Different solid granularities have different gravity and thus have different dropping speed.  The fine ore granularities floating

in the water will overflow and the big ones will sink to the bottom and discharge from the upper part by spiral pushing. It can

filter the granularities from the machine and then spin the rough particles to charging part by spiral vane and discharge the fine

granularities from the overflow pipe.
The base of the machine adopts channel steel material and the body adopts welded steel plate. The water inlet of spiral axle and axle head adopt iron cover for wear proofing and long life operation. The lifting equipment has two types, manual control and electric control.

Feature

  1). Large output, low energy consumption, high classifying efficiency
  2). The granularity is concentrative distribution, high classification precision
  3). Rational structure, fine applicability
  4). A high degree of automation
