The classifier uses the relative density of the fluidised bed between the two probes to determine the discharge rate of the high-density solids via a single central underflow valve.
The ores having ferro-magnetic minerals are suitable for magnetic separation methods. Some of the studies investigated flotation [7], and reflux classifiers [8] for beneficiating the iron ore fines or slimes. None of these methods are capable of treating all size ranges and types of iron ore satisfactorily.
View ALL our Spiral Classifiers Models. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
from heavy minerals, beneficiation of iron ore, coal washing. In some applications, UCC classifiers can be used in combination with Spiral Separators to achieve high product grade and recovery. Specific Mineral Applications Mineral Sands Silica Sand Titanium Minerals Iron Ore Coal Design Data
Spiral/Screw Classifier Speed. The speed of the conveyor should be just sufficient to handle the sands to be removed. The slower the speed the less the agitation in the pool and the finer the overflow. The lower the speed the longer the life of the classifier and all wearing parts. When and Where to use a Screw-Spiral Classifier
The REFLUX™ Classifier is a recently developed water-based gravity separation technology that is already being used worldwide to beneficiate particles above 0.100 mm in size. This paper reports tests performed on an ultra-fine iron ore with nominal top size of 0.106 mm, but with 59 wt-% being below 0.038 mm in size.

Because of the relatively coarse particle size in spiral classification, the classifier is widely used in primary or secondary grinding classification, as well as ore washing. Further Reading Sun Y-B (1993) Gravity separation.
The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014). The development of spiral ...
