Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types. They are high type single spiral classifier, high ... for the size grading of slurry in mineral processing plants and for desliming and dewatering
To understand how these two classifiers make use of this settling action, a description of them is required. First, to have the classification happen, the slurry must be able to flow. This means the classifiers must be inclined. The working portion of these two classifiers are the RAKES or SPIRAL/screw which are placed into the flow of ore. To ...

The Spiral Classifier is available with spiral diameters up to 120″.These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks.
Spiral classifiers and hydrocyclones are two types of classification equipment commonly used in mineral processing plants. The purpose of the classification operation is to effectively separate coarse and fine particles. As well as avoiding over-grinding of fine-grained minerals, while returning coarse-grained minerals to the mill for regrinding.
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 classifiers and rake classifiers are two . types of sedimentation classifiers. A typical . ... hydrocyclone classifiers. Minerals Engineering. 1996 Aug;9(8):881-91.
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 …
Cone Classifiers are built in two types, one op erating on the density of the pulp in the cone, and the other on the hydraulic or mechanical m ovement of the pulp. Cone classifiers have ...
The common feature of these two classifiers is that the overflow height will affect the sedimentation area. If the height of overflow increases, the sedimentation area will increase, the volume of the classifier would increase and the overflow particle size becomes coarse. ... selecting a spiral classifier for mineral classifying has relatively ...
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.
Bazin et al. (2014) have reported mineral size recovery curves of roughing, cleaning, and re-cleaning spirals at two Canadian iron ore processing plants. It was noted that rougher, cleaner and re ...

A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of the spiral trough …
Based on their separation principles, classifiers are classified into two major types. They are (i) wet classifiers, and (ii) dry classifiers. ... Although the hydrocyclone by nature is a size controlling machine the number of applications in mineral are many such as (i) classification in grinding circuits, (ii) dewatering and thickening, (iii ...

A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
7. WET CLASSIFICATION Wet classifiers are based on the principle that separation of coarse particles from fine particles by water or any other liquid.
