Spiral Classifier is mainly used in pre-classification and examination classification of grinding loop in concentration plant and aggregate plant as well as desliming, dehydration in sand washing process and so on.
Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the ...
Working principle of Spiral Classifier. Spiral classifier comes from the theory that granules with different dimensions and specific weights will sink in water at different speeds, fine mine granules float around in water or overflow, rough mine granules sink down to the bottom, so in this way the mechanical separation can be achieved ...
The entire spiral of the overflow end of the sunken classifier is submerged under the liquid level in the settling zone. The settling zone has a large area and depth. It is suitable for fine particle classification and can obtain an overflow particle size of less than 100 mesh. screw classifier in sand washing plant. How the spiral classifier works
To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and spiral classifiers, the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two.
1. Distributor Hopper. The ore distributor hopper is a slurry distribution device of a spiral chute, located at the top of the spiral chute. The ore distributor hopper is a fixed network pipe distributor, which evenly distributes the ore slurry from the …

Our aim is to work together with Mines, Mineral Beneficiation Plants for helping to reduce the operating cost,to improve the operating efficiency. Downloads ...
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 bottom of the classifier is ...
2 Resources and Methods Used 2.1 Materials and Equipment Intermediate product with particle sizes ranging from 0.075-3.35 mm and manganese grade of 43.9% - 49.8% obtained from the primary crusher section served as feed material to the Spiral Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul.

Fig.4 Photograph showing steep inner and shallow outer slopes of a spiral gravity separator. Fig.5 Disc element of simple spiral separator with cut to be made along AB.
The spiral had a uniform rectangular cross section with a width of 2 cm and a height of 0.5 cm. The outer radius of curvature of spiral was 5 cm. The closed spiral classifier was 3D printed in modular components using Stratasys's Mojo printer with P430 ABSplus and SR30 as print and support material, respectively.
Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill …
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 & Exploration Mineral ...
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
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 …
Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end.
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. …
Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage …
spiral classifiers -considering theirapplications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lotoftheirimportance due to the development ofcyclones. This trend, however, is now being reversed, and in the last few years there has been an increasing interest in spiral classifiers, in view oftheir

Spiral Classifier Working Principle The grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank.
