Spiral classifiers can grade different particles in ore slurry during the metal beneficiation process as well as deslime and dehydrate in the washing operation. They are widely used to separate ore sands by forming a closed-circuit with the ball mill in concentrators, or in gravity concentrators to classify ores and fine muds.
A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore.

This growth can be attributed to the increasing demand for efficient and accurate processing of materials.Spiral classifier is one of beneficiation equipment, based on user requirements, it can be ...
Besides that, for classifier fines, hydrocyclones are used for concentration by separating coarse material as most of the gangue constituents are found accumulated in the finer sizes. ... The Kirondal iron ore plant of Essar Steel Limited has successfully applied the spiral technique for the beneficiation of iron ore slimes to achieve a pellet ...
spiral classifier Centrifugal beneficiation mainly relies on centrifugal force to speed up the sedimentation and layering speed of fine particle size. It is suitable for processing fine particle size minerals of -0.1mm, because the production cost is relatively high compared with the general gravity selection method, and it is suitable for 37 ...
Vanadium-titanium magnetite ore benefication process, inclding below equipment: Ball mill; Spiral classifier; Magnetic separation; Dewatering machine; Filter machine; Thickener; Grinding: The raw ore enters the ball mill for grinding, and works together with the classifier to form a closed-circuit ring mill. Separation: After two stages …
Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank. Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand.

As the spiral classifier was assembled from modular components, experiments were repeated with spirals with different Number of Turns (NT) to understand its role on the ...
Description: Spiral classifier is one of the most common beneficiation equipment. The application of spiral classifier is very wide. It can separate the different grades products. It can separate the lighter …
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 ...
This Spiral Classifier is one of the equipment for beneficiation and a device for mechanical classification by the principle that the specific gravity of the solid particles is different. The powder level which can be ground in the ball mill can be filtered, and then the coarse material is screwed into the ball mill feeding port by the spiral ...

Spiral Classifier. spiral classifiers, also named screw classifiers, are designed to provide the most effective pool area and overflow velocity requirements by combining the proper submergence of the spiral with one of the tanks, a choice of 63 combinations is possible in straight, modified or full flare tank designs.The proper …
Abstract. Coal is the most abundant fossil fuel and about 42 % of the world electricity is generated through coal fired power stations. However, mechanized mining has led to an increase in the quantity of fine coal production. The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this …
Description. Spiral Classifier/ Screw Classifier is one of the beneficiation devices. 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 weir type single spiral classifier, high weir type double spiral classifier, immersed type single …
Spiral screw Classifier is widely used to control material size from Ball Mill in the beneficiation process, separate mineral sand and fine mud in the gravity concentration, and clean mud and water in washing mineral process. This machine has features of simple structure, reliable and convenient operation, etc.
Actually, the classifier has four types: high weir single and double spiral, immersed single and double spiral classifiers. High weir type: the top of the spiral vane is above the overflow surface, and the spiral center is under the overflow, mainly applied in classifying the size between 0.83-0.15mm.
Product introduction：Spiral classifier is commonly used in the grinding circuit of the beneficiation as the pre-classification and inspect classification machine and also in the ore washing and desliming operation.It is forms a closed cycle easily with the grinding machines with advantages of simple structure, reliable work and easy operation.
