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.
the nine types of classifiers described in this paper there are individual limits of application, as shown in Table I. Mechanical-hydraulic classifiers, equipped with either reciprocating or spiral rakes, are the most widely used and have countless applications. Unit-Type Classifiers Limitations: Unit-type classifiers are commonly
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 …
For most gold panning operations, a 1/4 inch classifier is a good choice. However, most prospectors have several classifiers of varying sizes at their disposal, to be able to pick the optimal size for the current site. The …

The Optima Classifier is a homegrown, South African innovative gravity separation proprietry technology, developed by Gravitas Minerals aimed at fine coal and mineral separation. It offers the industry a cost-effective solution with a reduced carbon footprint and far-reaching future ESG (Environmental, Social and Governance) value adds.
This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the …
The commonest equipment in Ore Dressing are cyclones and spiral classifiers. The following work provides a comparison between these two devices as to their application in the mineral industry, as well as parameters for costs estimates. CYCLONES. Cyclones …
Allen Cone Classifier. ALLEN Sand Cones and Allen Slime Cones have application in ore-dressing, chemical and industrial processes for classification, dewatering, de-sliming, leaching and washing.
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.
Because the different structure between high dam spiral classifier and submerged spiral classifier, so they play different role in the classification operation. The high dam classifier is more suitable for the coarse particles (larger than 0.15mm), which is often used in the first stage grinding.
Which type of classification equipment should I choose? 1. Granularity of processed materials. Common spiral classifiers include high type and submerged type. The high type is usually used for …
Spiral Classifier In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates …

Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).
Which type of classification equipment should I choose? 1. Granularity of processed materials. Common spiral classifiers include high type and submerged type. The high type is usually used for coarse-grain classification, and the diameter of the overflow particle size of the classification is generally greater than 0.15mm.
The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components.
The commonest equipment in Ore Dressing are cyclones and spiral classifiers. The following work provides a comparison between these two devices as to their application in the mineral industry, as well as parameters for costs estimates. CYCLONES. Cyclones or hydrocyclones are recently-developed devices.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for …
The double vortex-finder hydrocyclone formed by a coaxial insertion of an internal vortex-finder with a smaller diameter inside the conventional single vortex-finder used to obtain two kinds of products from the internal and external overflows in one classification has attracted wide attention.
