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.

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 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

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
The Spiral Classifier is available with spiral diameters up to 120". These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. All sizes and models are available with single-, double- or triple-pitch spirals. The Spiral Classifier offers the greatest sand raking …

It greatly increases the recovery of fine gold. 12. Flood Gold by Dennis Krupnak, California: After a heavy rain, test pan the side streams that form off the main stream channel. Many are just small diversions that flow back into the main stream. They are often good sites for fine flood gold, which will be close to the surface.
1. Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).The …
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.

Classifiers for gold prospecting and gem hunting come in several shapes and sizes to help classify paydirt into a size that is easier to process. Our most popular classifiers are 14" across and fit on top of a five-gallon bucket. This allows one person to shovel paydirt onto the classifier and the other person to shake it down to size.
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.
When gold prospectors select any dry creek leading down from mineralized mountains, they nearly always find a few pockets of placer gold dust that can add up to a few ounces of gold. The best part is that they are often replenished during the annual floods, so that means you can go back to the same spot again and again and reap the rewards!
