Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...
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 ...
Originally known as Humphreys spiral (after the inventor) a wide range of devices are now available. A spiral concentrator consists of a helical conduit of semi-circular cross …
Classifiers have found wide applications in the mineral processing industry. In this study, a novel enhanced gravity closed spiral classifier is presented. This device uses induced centrifugal force to classify particles. A functional prototype of the separator was 3D printed to experimentally validate the concept. The performance characteristics …
Contact Now +86-. Published time：27 September 2023. 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 ...
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 spiral classifier is one of the size-classifying equipment for the mining industry.

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 …
Working Principle: 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 …

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.
A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier ...
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.
The closed spiral classifier was 3D printed in modular components using Stratasys's Mojo printer with P430 ABSplus and SR30 as print and support material, respectively. The key design aspect of the spiral classifier is the inline flow splitter that divides the outlet stream into inner outlet (tails or finer) stream and outer outlet ...

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.
Spiral Classifier. 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.

cost and less space required have caused operation with spiral classifiers to becomerestricted. The application range ofspiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing
