Copper ore beneficiation line machinery screw classifier
Spiral classifier introduction:
Spiral Classifiers are widely used in the distribution of ore in closed circuits with ball mill in mining processing, in order to get a certain degree fineness of ore particles, meanwhile, increasing the efficiency of grinding. This machine can also be used to wash sand, classify ore sand and play other functions.

Spiral classifier application:
1. Spiral Classifiers are widely used in the distribution of ore in closed circuits with ball mill in mining processing
2. Used in gravity concentration for classifying ore sand and clay.
3. Metal ore dressing procedure for ore size grading
4. Ore washing assignment for ore desliming or dehydration

Spiral classifier working 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
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 a channel steel and the body adopts welded steel plate. The water inlet of spiral axle and axle head adopt pig iron cover for wear proofing and long life operation. The lifting equipment has two types, manual control and electric control.
Spiral classifier features
1).This product features simple structure, reliable working conditions and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to flow in the water, while coarse ore sinks to the bottom.
2).This 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 machines lifting equipment can be used manually or electronically.
