Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
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 of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE Spiral Classifier is ...

Larger sand grains collect in the bottom of the trough and are lifted up the inclined plane to be discharged by the spiral shaft. During this process, the screw device works to ...
Common spiral classifiers can be classified according to the overflow height, that is, the position of the spiral in the water tank is different from the height of the pulp surface. The spiral classifier can be divided into three …
Features of Spiral Classifier. High-efficiency grinding: The rod mill adopts optimized grinding media and grinding chamber design to ensure that the materials are fully ground during the grinding process and improve the grinding efficiency. Uniform particle size: Through the uniform distribution of rod-shaped grinding media and rotary movement, the rod mill can realize …
Spiral classifier is a common classification equipment used in mineral processing plants. It has the characteristics of simple str...
Work Principle. The spiral classifier is based on the principle that the solid particles are different in size and specific gravity, so the settling speed in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink to the bottom of the tank and are pushed upward by the screw. ...
The entire spiral of the overflow end of the sunken classifier is submerged under the liquid level in the settling zone. The settling zone has a large area and depth. It is suitable for fine particle classification and can obtain an overflow particle …
Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster shells, solar and …
Spiral Classifier. Reference work entry; First Online: 01 January 2024; pp 2010; ... 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 ...
(1) The spiral blades at the lower end of the submerged spiral classifier are all immersed in the pulp with the largest classification area, which is applicable to the processing of fine materials. (2) The spiral blades at the lower end of the high- spiral classifier are partially immersed in the pulp with smaller classification area.
Table 1 The Test Works for the Classifier This paper therefore seeks to optimize the operational parameters (speed of the spirals, feed tonnage and the resident time for washing) of the spiral classifier incorporated in the oxide washing plant to upgrade the final product grade (grade >51) by employing the Design of Experiment, DOE.
Unlike the rake and spiral classifiers, the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two. ... To understand how pumps work we will have to leave their relationship to cyclones until we have discussed …
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 …
How it works: Pulp is introduced at the top of the spiral and flows downward. As the pulp follows the spiral channel the light particles in the pulp stream move outward and …
For silica, the spiral classifier had a cut size in the range of 82-108 μ m, whereas for iron ore the spiral classifier had a cut size of 38-66 μ m. Hence, there is a gap between the range of D 50 c values observed in silica and iron ore. As particle loading increased, the particle–particle interaction intensified, and the flow regime may ...
Spiral classifiers, such as the Alpine Mikroplex design for separation in the superfine region, were developed to partially overcome undesirable boundary layer effects associated with spinning fluids at stationary walls (Rumpf and Leschonski (1967)). Air is introduced tangentially at the periphery into a flat cylindrical space and moves along ...
In production, many concentrators more or less encounter the problem of obvious decline in the classification efficiency of spiral classifier, and the root cause of this problem lies in the disordered settlement of fine and heavy ore particles and coarse and light ore particles in the classification process, resulting in equal drop phenomenon, resulting in a large amount of fine sand inclusion ...

It works with the spiral classifier, so the overflow slurry from the classifier is about 80% 200mesh powder. The oversize particle from the classifier will go back to ball mill grinding again, to form a closed-loop. The 200mesh slurry will be pumped to a gravity separation machine, spiral chute, and shaking table. The spiral chute is for ...
Centrifugal classifiers include the solid bowl cen- trifuge and the cyclone classifier. The solid bowl centrifuge, Fig. 10, consists of a truncated cone fixed to a horizontal shaft and rotating at high …
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.
