Spiral classifier or hydrocyclone
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 & …

Classification
Some spiral classifiers have flared sides. This increases the capacity. For example, in a simplex type H classifier, the capacity is increased 1.3 times and for a duplex type H classifier, the capacity may be increased two to three times. The feed size of particles to spiral classifiers is in the region of 150 μm and coarser.

An operational model for a spiral classifier
The proposed model divides a N T turn spiral into N HT half turns (N HT = 2N T) as illustrated in Fig. 2. The use of a half turn as a discrete unit is related to the fact that some spiral types may have two concentrate ports and two wash water addition points per half turn. It is also possible to use one turn or a quarter of turn as the ...

spiral classifier
The spiral classifier is based on the principle that the size and specific gravity of solid particles are different, so the settlement speed in the liquid is different. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank and are pushed up by the screw for mechanical classification.
