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causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated.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 …

on a slope, with interrupted rake or spiral blades to move the settled solids to a central discharge cone. Tank diameters vary from 4 to 250 ft. Tank depths at center are 2 to 3 ft for small units and up to 25 ft for larger units. Hydraulic classifiers of the sizer and super-sorter types, Figs. 7 and 8, are narrow, deep, rectangular

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

The rotation speed of the commonly used spiral classifier is. To obtain coarse overflow, the speed of the spiral with a diameter of 2 m should not exceed 6 r/min, and with a diameter of 1 m or more should be controlled at 2-8 r/min. For example, for a spiral with a diameter of 0.3 m, in order to obtain a coarse overflow, the spiral speed can be ...

Gravitational inertial air classifiers use a primary and a recirculating secondary airflow to separate fines from coarse particles. Because the airflows are not affected by wear, the grading remains consistent to an accuracy of microns. At the same time, particle moisture remains at an optimal level. Different fractions ranging from 300 μm to ...

Spiral Classifiers. The Akins, Hardinge, and Western Machinery are examples of the spiral. The first two consist of a spiral rotating in an open steel trough or box set on a slope, the spiral working the sand to the upper end and the slime overflowing at the lower end. Spirals of 8 to 12 inches diameter are available for small plants.
