Spiral Classifier for Mineral Processing. The design of these classifiers (rake spiral screw) have inherent problems First they are very susceptible to wear caused by the scrubbing action of the ore that plus all of the mechanical moving parts create many worn areas to contend with.
More MessageHongji Group Product Superiority. Spiral classifiers or screw classifiers are important ore dressing equipment. Spiral classifier is mainly used in metal beneficiation production line to classify minerals according to their different sedimentation velocity. Screw classifiers can be divided into high weir type low weir type and sank type according to the height of the weir.
More MessageThe design of these classifiers (rake spiral screw) have inherent problems First they are very susceptible to wear caused by the scrubbing action of the ore that plus all of the mechanical moving parts create many worn areas to contend with. The other problem that these classifiers have is that they are easily over loaded.
More MessageRake classifiers are also used for close circuit grinding. Both rake and spiral classifiers are more efficient in classifying the coarse particles. But they are very costly for installation. In these classifiers the separation achieved is distinct. Dry classifiers. Dry classifiers are based on the principle that separation by air fluidization.
More MessageRake Classifier 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.

More MessageRake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake. Spiral classifiers use an Archimedes pump screw to lift solid-liquid mixtures up onto a screen for dewatering. Bowl classifiers bowl desilters hydroseparators or countercurrent classifiers are other types or mechanical classifiers.
More MessageThe J A Crossflow grit removal unit is typically installed between medium and fine screens to capture abrasive material. It features a wide shallow and square collection tank with a series of vertical baffles to assist in the equal distribution of the flow entering the tank. This design forms a recessed circular sump. Solids accumulate herein and are transported by a scraper to a collection

More MessageJan 01 2016 · 13.2.2. Rake Classifiers. When rakes are used in place of spirals the classifiers are called Rake classifiers. These are less common than spiral classifiers. The rakes consist of one or more parallel lines of steel plates that hang from a central shaft or shafts. The plates are hinged onto these shafts and have a reciprocating movement.
