Description

Spiral Classifier : according to the spiral blade at the flooding end, there are two types, high weir type: the top side of spiral blade is higher than the flooding level and the center of the blade is lower than the flooding level. This type is used for classification of ore with flooding size between 0.***0.*5. ***** weir type: the whole spiral blade is immersed in the flooding level of the flooding end. The type is used for classification of ore with flooding size between 0.**- 0.*7mm. Our spiral 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. 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. 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.
