Grit Classifiers are used to separate materials. A shaftless spiral extracts the material, eg sand, that settles at the bottom of a trough. The shaftless spiral allows the material to travel automatically through the system to a recovery or disposal container. Our Grit Classifier is strong and Built to Last ®.
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
Unit-type classifiers, bowl classifiers, and bowl desiltors are all rectangular tanks, slightly tilted, with reciprocating rakes or screws to remove settled sands. The unit-type classifier, Figs. 1 and 2, is available in widths from 14 in. to 20 ft and lengths up to 40 ft. The shallow bowl of the bowl classifier,

Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.

Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the sloping sides of the tank and dredges the thick sludge out of the tank. Figure 13.2 shows the spiral conveyor replaced by a rake, which drags the sand up the incline for discharge. Download : Download full-size …

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)
It is employed when separating sand from slimes, concentrating of smaller heavy-gravity mineral particles from large light-gravity mineral particles and sort solids of long range screen sizes into short range fraction ( Jones, 1985; Swain, 2011). ... Fig. 1 A typical Spiral Classifier (Wills, 2006) Records indicate that since 1916 when ...
Bent spiral blades or spokes. Solution: By repairing or replacing new spiral leaves and spokes. 4. Gears are easily damaged. Solution: The damaged gear should be replaced in time and maintained regularly, and the sand washer shaft should reach the specified level. 5. Vibration of lifting rod.
Spiral classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. …

Fine Material Screw Washers are typically used for washing and dewatering -5mm x 0 sand, fines or coarse tailings, and for removing silts and/or clays being nominally -75 micron or 200 mesh. These units are also referred to by other names such as screw classifiers, spiral classifiers and sand screws.
DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation …
cost and less space required have caused operation with spiral classifiers to becomerestricted. The application range ofspiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing
Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
Boratas spiral classifier is a machine that is mainly used to separate slimes from sand and sandy-sized materials. The resulting products are the underflow which is a partly dry fraction containing the rough material and the overflow which is a fine fraction along with what's left of the liquid medium portion.

The Spiral Classifier offers the greatest sand raking capacity of any classifier available. (3) The tank is a heavy plate with a strong structural base. The extra heavy shaft has an improved submerged bearing. The greatest improvements, however, are found in the drive-unit which has been strengthened and improved over all other classifiers.
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 …
