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.

6 Differences between Spiral Sand Washer and Spiral Classifier. August 10, 2022. ... Spiral classifier is widely used in concentrator and work with ball mill to form a closed-loop distribution for ore, or used in gravity concentrator to grade ore and fine mud, and metal ore dressing process for pulp size classification, as well as for desliming ...

The spiral classifier rotates at a low speed through the spiral to stir the pulp to make the fine particles suspend to the top and overflow to the overflow weir. In contrast, the coarse particles sink to the bottom of the tank and are conveyed to the discharge port by the screw to be discharged as returned sand, while The hydrocyclone needs to ...

The obvious difference is the difference between the blades. The blade of the spiral sand washer is solid blade type, and the blade of the spiral classifier is suspended hollow blade. 2. Working principle. The spiral sand washer should be arranged in an inclined way.

Spiral concentrator machine is widely used to pre-grading and inspection grading in closed circuits when used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified.

Spiral concentrators are modem, high capacity, low cost units developed for the concentration of low grade ores. Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate take-off ports placed at regular …

Rake Classifier. The Rake Classifier is designed for either open or closed circuit operation. It is made in two types, type "C" for light duty and type "D" for heavy duty. The mechanism and tank of both units …

efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Spirals require a minimum of maintenance and upkeep, and offer a relatively simple unit operation that translates to low capital and operating cost.

The typical spiral unit consists of a spiral conduit with a modified semi-circular cross section. As the slurry flows down the spiral, those minerals with highest specific gravity move to the inner edge of the spiral while the light material moves upward to the outer edge of the spiral. A full size spiral concentrator is shown in Figure 2.

The. capacities of the spiral concentrators range. between 1 and 3 t/h dry solids and recently in. excess of 7 t/h in the case of high capacity. spiral concentrators when treating typical. heavy ...

Specific Gravity Range: Spiral concentrators work best when there is a significant difference in specific gravity between the valuable minerals and gangue material. Spiral concentrators are widely used in mineral processing operations, especially for the concentration of heavy minerals like zircon, rutile, iron ore, and coal.

Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As …

Here are several common applications of spiral classifiers in the ore beneficiation process: Particle Size Classification: Spiral classifiers are extensively employed to classify raw ores or ore ...

The Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with 100%, 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.
