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.

Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.

The most common classification equipment currently used in concentrators is spiral classifiers and a hydrocyclones. (1) Spiral Classifier. Spiral classifiers achieve classification function by means of the different sedimentation speed that different-sized ore particles shows in the aqueous medium.
The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able to pull the course ore backwards further than it can travel forwards, then eventually the bigger particles will be pulled all the way ...
It is evident that D 50 c increased with increasing particle loading for both silica and iron ore systems. For silica, the spiral classifier had a cut size in the range of 82-108 μ m, whereas for iron ore the spiral classifier had a cut size of 38-66 μ m. Hence, there is a gap between the range of D 50 c values observed in silica and iron ore ...
A comprehensive numerical analysis of the fluid flow and dilute particulate flow in the LD9 spiral separator is presented in this work. The air–water flow field on a coal spiral is simulated using the volume of fluid (VOF) coupled with RANS turbulence models. Water depth and flow field predictions by RSM show close agreement with experiments.
Compared with these two classifiers, the hydrocyclone has a better classification effect when processing finer-grained materials (the separation particle size range is generally 0.3-0.01mm). 2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier.
