removed by and dewatered in the discharge spiral and can be sent to re cycling if this is considered of value. Robust design fo reliable operation Like the spiral classifier the spiral dewaterer consists basically of an open tank for sedimentation of solids and a transportation spiral for removal and dewatering of the settled product.
Our spiral classifier is a kind of equipment for mechanical classification based on the principle that solid particles have different sizes and specific gravity, so the speed of sedimentation in the liquid is different. Its long and narrow tank body can make the stirring effect ideal and prolong the suspension time of materials in water.

The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster …
The application range of spiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser …
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.

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causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated.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