Abstract. Spirals are gravity concentrators used for the valorization of coal and heavy minerals. Coarse hematite iron ores in Canada are usually concentrated by spirals. Spirals classify the particles according to their size and specific gravity. Several mathematical models were proposed to simulate the operation of spirals using a balance ...

It is obvious that the floor area of hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the hydrocyclone covers an area of only l/30 to l/50 to the spiral classifier. The equipment floor area requirement also limits the application of the spiral classifier to a certain extent. 3. Classification Efficiency.

The submerged spiral classifier is suitable for fine particle classification, and the overflow particle size of the classification is usually less than 0.15mm. Compared with these two spiral classifiers, the hydrocyclone has a significantly better classification effect when dealing with finer-grained materials (the separation particle size ...

Spiral Classifier. 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. The motion of the spiral creates Pool Hindered Settling in the bottom pool area ...

Submerged spiral classifier The submerged spiral classifier is the one whose spiral blades at the overflow end are completely immersed below the overflow surface. It has a small settlement area and low overflow production capacity, so it is mainly suitable for ore classification with an overflow particle size of 0.15–0.07 mm.

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 concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …

Ghana Manganese Company (GMC) has renovated their oxide washing plant by integrating it with a spiral classifier to make a batch system operating process. Particle size of <3.35mm (Mn grade of 43-47%) obtained from the primary section of the plant served as feed to the classifier and with the plant condition (i.e. at 60 min washing time, 30 ...

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 …

Now, the common classifiers in mineral processing plant are mainly mechanical classifier and hydrocyclone. Among them,mechanical classifier can be divided into spiral classifier, rake classifier,tank classifier and other types. With the development of classification operation, rake classifier is already replaced by spiral classifier, tank ...

Grit classifiers can range from 12" to 24" in diameter (12" is the most popular size). Grit classifiers are sized by hydraulic flow of gallons per minute (GPM) and solid conveyance for the screw conveyor. Influent flow drives the size of the hopper and whether a hydrocyclone should be considered.

The spiral classifier is based on the principle that the size of the solid particles and the specific gravity are different, so the sedimentation speed in the liquid is different. It is a kind of grading equipment that is pushed up by the screw and discharged to the top for mechanical grading. It can grade the powder in the mill for filtration ...

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.

For silica, the spiral classifier had a cut size in the range of 82-108 μ m, whereas for iron ore the spiral classifier had a cut size of 38-66 μ m. Hence, there is a gap between the range of D 50 c values observed in silica and iron ore. As particle loading increased, the particle–particle interaction intensified, and the flow regime may ...

Screw Classifiers. To be successful in a obtaining a uniform grind that is necessary to achieve a high percentage of recovery it is necessary to control the degree of fineness that the ore is reduced to. This is done by separating the fine material from the course and regrinding the coarse until it is fine enough for efficient mineral extraction.
