Spiral classifier is suitable for the flow ore sand in the beneficiation plant, the particle size classification of the ore pulp in the metal beneficiation process, and the desliming and dewatering operations in the ore washing operation. It is especially suitable for washing, grading, impurity removal, and fine-grained and coarse-grained material …

Abstract. Design features of the commonly used classifiers such as the spiral, rake, cone, bowl are described. Descriptions and design of centrifugal classifiers, such as the hydrocyclone, are given in some details. The mathematical aspects of designs that are related to operation of these classifiers and the theory behind the design and ...

Spiral Classifier has been widely use in closed-circuit grinding operations and it can also be used for the classification of ore sand and slime in gravity beneficiation plants, for the size grading of slurry in mineral processing plants and for desliming and dewatering in ore-washing plants.

Spiral Classifier. Capacity: 21-1785 t/24h (over flow); 145-23300t/24h (returned sand); Up to 150% spiral submergence. Spiral diameter: 500-3000mm; Single, double or triple pitch spirals are available. Application: …

2). Low Dam Spiral Classifier. The low dam type is that the overflow dam is lower than the screw axis of the screw. Due to the small area of the settling area, it can only be used for washing sand ores with little mud and dewatering of coarse particles in actual production, but it is rarely used in grinding cycles. 3). Submerged Spiral Classifier

The vibrating classifier equipped with an elastic screen surface improves the efficiency of excitation energy transfer. The vibrating parameters and the liquid-solid ratio of tailings are the key factors affecting the classification-dewatering efficiency. The classification-dewatering efficiencies of tailings are 80% and 53%, respectively.

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 …

Spiral dewaterer 5 Spiral Dewaterer Principle of inclined plate packs. model - SD spiral dewaterer model SD is a robust evolution of the spiral classifier for reliable operations in mill scale handling. The spiral dewaterer with special designed spiral and enlarged pool area is able to handle large flows of effluents, offering a well

The SpiraSnail ® is a highly efficient screw-type grit dewatering system that delivers 95% removal of all particles 106 micron and larger and 75% of 75-106 micron particles to cut solids handling and disposal costs. …

Dewatering Cyclone: If the feed is fairly coarse, the cyclone will split almost all of the water, with very little solids to the overflow. Almost all of the solids will report to the underflow, at a higher pulp density than the feed. Here, the cyclone underflow is the required product, and underflow density is the critical factor.

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 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. ... Dewatering: Spiral classifiers dewater or remove excess water from mineral slurries. Settling and separating particles, help concentrate the valuable minerals and ...

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 ...
