Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting …
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...
2. Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough ( Burt, 1984 ). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.
A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier ...
Spiral 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 ...
Because users' needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user's classification requirements. Spiral …
Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction …

on a slope, with interrupted rake or spiral blades to move the settled solids to a central discharge cone. Tank diameters vary from 4 to 250 ft. Tank depths at center are 2 to 3 ft for small units and up to 25 ft for larger units. Hydraulic classifiers of the sizer and super-sorter types, Figs. 7 and 8, are narrow, deep, rectangular
Spirals classify the particles according to their size and specific gravity. Several mathematical models were proposed to simulate the operation of spirals using a …

This work provides a comparison between the most commonly used classification equipment in the treatment of minerals - hydrocyclones and spiral classifiers - considering their applications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lot of their importance due to the development of cyclones. This …
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 ...

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)
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 …

Spiral Classifier. Capacity: 21-1785 t/24h (over flow); 145-23300t/24h (returned sand); Up to 150% spiral submergence. Spiral diameter: 500-3000mm; Single, …
Grit Classifiers are used to separate materials. A shaftless spiral extracts the material, eg sand, that settles at the bottom of a trough. The shaftless spiral allows the material to travel automatically through the system to a recovery or disposal container. Our Grit Classifier is strong and Built to Last ®.
Spiral classifiers, such as the Alpine Mikroplex design for separation in the superfine region, were developed to partially overcome undesirable boundary layer effects associated with spinning fluids at stationary walls (Rumpf and Leschonski (1967)). Air is introduced tangentially at the periphery into a flat cylindrical space and moves along ...
