Spiral Classifier for Mineral Processing
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 …

CLASSIFIERS
CLASSIFIERS. Classification is a process of dividing a particle-laden gas stream into two, ideally at a particular particle size, known as the cut size. An important industrial application of classifiers is to reduce overgrinding in a mill by separating the grinding zone output into fine and coarse fractions.

7. WET CLASSIFICATION Wet classifiers are based on the principle that separation of coarse particles from fine particles by water or any other liquid. In wet classifiers coarse particles move faster than fine particles at equal density. High density particles move faster than low density particles at equal size. Industrial classification may …

Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …

Centrifugal air classifiers offer effective fines screening
Air classifier advantages. The accuracy of mechanical centrifugal air classifiers makes them ideal for when the separation curve or cut point is too fine for screens (200 to 400 mesh or finer), when the capacity is too large for screens (up to 800 tonnes per hour) and when system flexibility is required to meet various product …

The flotation tailing product at 25 to 30% solids contains the clean silica sand. A SRL Pump delivers it to a Dewatering Classifier for final dewatering. A mechanical classifier is generally preferable for this step as the sand can be dewatered down to 15 to 20% moisture content for belt conveying to stock pile or drainage bins.
