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 spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.
An inspection of the classifier systems in O/ZWR showed the need for effective methods of corrosion protection for classifiers [13, 14]. For this reason, the development of technology for the ...
Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers.

The application range of spiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. …
The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and other operations in mineral …
The spiral classifier is primarily used for closed-circuit operation with ore grinding equipment or ore washing, dehydration, desliming, etc., and has a better classification effect on coarser particles.
