2013 High Quality Classifier on Sale from shanghai
Flotation classifier introduction:
Flotation classifier, one of the beneficiation equipments, which classifies the ore materials mechanically.The theory is “ the precipitation speed is different for the different specific gravity of solid materials.” It can fliter the material powder from the grinding machine, then puts the coarse material into the feeder of grinding machine by the spiral slice and discharges the filtered fine materials from the overflow pipe.
Our Flotation classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing. Advantages are simple structure, reliable working condition and convenient operation.
Flotation classifier working principle:
According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe. The seat of the machine adopts channel steel and body adopts armor plate and the spiral axle adopts wrought iron, so it’s durable. The lifting equipments have two types, by electricity and hand.
