Rake and spiral classifier

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 The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated

    Jan 01, 2016 The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow. Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the

    A bowl and rake classifier is typically used to separate coarse and fine particles of granular material temporarily suspended in water. The coarse particles settle to the bottom of the vessel and are scraped by a set of blades. The fine particles are carried over the edge of the classifier. This is how the offered rake classifier works

    The Tuke & Bell Rake Classifier is a multiple-rake reciprocating mechanism, mounted within a cleaning channel, which is a narrow, continuously sloping ramp. The reciprocating action moves the grit, up the ramp towards a discharge point above top water level. At this point the grit is free of water, which assists easy and efficient disposal, and

    EIMCO-K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are (1) a partially drained fraction containing the coarse material (called the underflow) and (2) a fine fraction along with the remaining portion of the liquid medium (called the overflow)
