Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

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

This paper focused on the optimisation of some selected operational parameters of the classifier to obtain a Mn grade >50% using Design of Experiment (DOE). Series of test works were designed using the DOE for the classifier using the constraints of washing time (30-90 min), speed of spirals (20-40 rev/min) and feed …

design variables. This study shows that a spiral classifier model can be developed based on concepts of d50 (corrected) and the reduced-performanee curve as is done for the hydrocyclone classifier. A significant finding is that use of the finest size fraction in the coarse product is the most effective

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. Due to the induced centrifugal acceleration, heavier or coarser particles migrate faster towards the outer wall leaving behind the ...

2. Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough ( Burt, 1984 ). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …
