Spiral Classifier
Processing ability:6-400 tph
Brief 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 etc.
Applications:
Metal ore such as gold, silver, copper, Lead (Pb), Zinc (Zn), Tin, Nickel (Ni) and so on. It also can be used to wash sand.
Features:
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.
