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.
The Reflux Classifier is an innovative device offering advantages in both particle size classification and gravity separation. The system is a combination of a conventional fluidised bed and sets of parallel inclined plates as used to achieve a high throughput in a lamella settler. A reflux action develops as a result of fluidised particles ...

The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able …
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.
The iron ore feed had a head grade of 35 wt-% Fe T. At a low feed solids mass flux of 1.5 t m −2 h −1, the REFLUX™ Classifier produced high-grade products at …
Further research to study the iron-ore slime (fines) beneficiation is ongoing. The novel closed spiral classifier creates around 80–180 G-force. Our CFD study estimates that the shear rates in the equipment wil be of the order of 10 3 s −1, whereas hydrocyclones will generate around 10 4 s −1 at similar process conditions . Thus, it may ...
14 experiments were conducted on the Reflux Classifier using two itabirite iron ore feeds. • The experimental conditions covered set points, feed pulp densities, throughputs, fluidization rates and channel spacings. • The work showed the potential of a single stage gravity separator in upgradingminerals down towards sizes of 10 μm.
