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.
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 …
The size of mechanical classifier required for a particular job depends on the following factors: 1. Tons of dry solids to be overflowed per 24 hours. This is simply a predetermined tonnage. 2. Mesh size at which separation is to be made. The mesh size is determined by laboratory tests or is already known from previous ex…

The spiral classifier is one of the important equipment in the mineral processing process. Its principle is to use the difference in the settling speed of solid particles in the liquid to classify materials. The classification effect of the spiral classifier will directly affect the content of qualified products in the returned sand, thus affecting […]
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.
The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow. Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the ...
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 classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. It is also used for or washing clay sand, silica sand, tailings dehydration, tailings water separation, etc. It is one of the main equipment for mineral processing.
if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The formed spiral would also slope inwards towards the supporting cylinder. This is the important angle β of fig.1 and is given by: tanβ = 2(D2-D1) (5 ...

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 represented by the number and diameter of spirals. The bottom of the classifier is ...
The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling.
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 shells, solar and potash salts.
3.1 High Spiral Classifier. Design: The spiral blade extends above the slurry surface. Application: Ideal for separating coarse particles and used in rough grinding stages. Advantages: Simple design and cost-effective. 3.2 Submerged Spiral Classifier. Design: The spiral blade is entirely submerged in the slurry.

Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul. 2.2 Designing of Test Works Prior to test work design, visit to the oxide plant at Ghana Manganese Company (GMC) were made with the aim of getting acclimatize with the current operations at the plant. The Spiral classifier was operated in batch mode.
Thus, Spiral behaviour to different operating parameters has been predicted qualitatively by many authors. Besides it, many authors attempted to predict the performance of spiral quantitatively but the successfulness is limited (Holtham 1992 and Loveday 1994). In the current work, spiral behaviour has been studied subjecting to different
Grit Classifiers are used to separate materials. A shaftless spiral extracts the material, eg sand, that settles at the bottom of a trough. The shaftless spiral allows the material to travel automatically through the system to a recovery or disposal container. Our Grit Classifier is strong and Built to Last ®.
