The design of closed spiral classifier (CSC) is inspired by the open spiral separators and hydrocyclones [19], [20]. Feed slurry is passed through a closed rectangular spiral channel at sufficiently high velocity. ... A vertical splitter placed at the end of the channel separates the out flow into the inner (finer) and outer (coarser) streams.
One effective way of gaining a quantitative insight into spiral separator geometry is to consider the construction of a simple model separator. All that is needed is a cardboard disc, with a hole, glue and a vertical tube. Fig.5 shows the required shape of the disc. Fall 2006 26 The Shot Peener PRINCIPLES OF SPIRAL GRAVITY CLASSIFICATION
Basically the different wet classifiers are g ravity settling tank, cone classifier, double cone class ifier, hydrocyclone classifier, spiral classifier, and rake classifier. 3.2 Gravity settling tank

Factors in machine construction: The inclination angle of the trough, the rotation speed of the screw, shaft, and the width of the trough. Operational factors: …
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
The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and …
Spiral classifiers Designed for optimal performance spiral classifiers 's spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. By combining the proper submergence of the spiral with one of the tank designs a choice of 63 combinations is possible in straight, modified or full ...

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 …
Spiral classifier is mainly composed of the driving device, the spiral body, the groove body, the lifting mechanism, the lower seat and discharge valve. The machine base adopts channel steel, the body adopts welded steel plate. Screw shaft parts use the pig iron, and wear resistance. Working Principle:
Rake 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.
Spiral classifier solutions Dewatering Dewatering Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.
1. Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).The …
