Spiral classifier is one of beneficiation equipment, based on user requirements, it can be divided into single and double spiral classifier. Depend on specific gravity of solid particles, so different sedimentation velocity in a liquid principle, spiral classifier is a mechanical grading equipment. Feed mill can grind the powder level in the filter, and then use the coarse material spiral piece rotary vane screwed mill feeder to filter out fine material discharged from the overflow tube.
According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Waste mud or water for ore sand can be separated from the ores. It’s also usually applied to ore washing, desliming and dehydration and so on.
Advantage
1. Low power cosumption,high classifying efficiency
2. Heavy duty, long workinglife
3. Powerful manual control and electric control lifting device
4. Wide choice of weir height, rigid tank and substructure
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 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.

The spiral classifier tank is heavy plate with strong structural base. The extra heavy shaft has an improved submerged bearing. The greatest improvements, however, are found in the drive-unit which has been strengthened and improved over all other classifiers. A specially designed classifier reducer eliminates the “over – hang” or cantilevered load normally found where the reducer shaft carries the pinion. The Classifier Reducer has an outboard bearing integral with the reducer base which provides positive alignment of the bevel gears.
Baichy headquarters is located in the industrial park in Jiaozuo City. It covers a total area of 200,000 square meters, including 150,000 square meters of standarized workshop. There are more than 200 sets of various large and medium-sized metal processing lathe, riveting machine, welding equipment and assembly equipment. We have more than 500 workers, including more than 20 middle and senior technicians. Baichy is mainly focus on 4 series products: stone crusher machines, sand making equipment, powder grinding mills, mineral processing equipment and their spare parts. Every year, Baichy can turn out 1,000 sets of crushers and 10,000 tons of crusher parts.
