The operating guidelines for coal spiral circuits are discussed. Spiral circuits serve as a low-cost method to recover fine coal. By avoiding problems such as poor feed distribution, improper solid and liquid flow rates, incorrect splitter settings and poor circuit layout, plant operators can easily optimize spiral circuits. Original language.

Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

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)

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 …

Spiral concentrator is the key operating unit and is widely used for concentrating different minerals and coal. Normally in mineral processing a rigorous and costly experimental evaluation of laboratory and pilot-scale equipment trials are conducted for accessing the performance of any unit operation.

SYNOPSIS. Spiral concentration forms a crucial part of gravity separation circuits. The application of process models in the operation of gravity separation circuits offers significant benefits in recoveries and grade control. Significant strides in the modelling of spiral concentrators have been made during the last couple of decades.
