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 & …
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.
Dilution discharge ball mill atau umpan spiral classifier dapat dinyatakan dengan menggunakan rumus berikut. D BM = (1 – S BM)/S BM. S BM = 50% = 0,5. D BM = (1 – 0,5)/0,5. D BM = 0,5/0,5. D BM = 1. jadi, dilution dari keluaran atau discharge ball mill yang juga umpan classifier adalah 1, Artinya laju air dan solid atau padatan adalah sama.

A Spiral Jet Mill is also called a pancake jet mill. The spiral jet mill is suitable for the fine and ultrafine size reduction of materials up to a Mohs hardness of 9 that display brittle crystalline grinding characteristics. They are typically used in applications where a high ultrafine portion is required.
JXSC grinding & classification equipment is the key equipment for crushing materials after they are crushed. The ball mill can process various grinding minerals, non-ferrous metal beneficiation, and new building materials. It is often combined with a spiral classifier to form a closed-circuit ring mill, which has higher fine powder and grinding power.

Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. ... it can be directly returned to the grinding mill for regrinding. According to the number of spiral shafts, the spiral ...
The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) …
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.
Spiral classifier is mainly composed of the driving device, the spiral body, the groove body, the lifting mechanism, the lower seat and discharge valve. ... It can put the coarse material into the mill inlet by using spiral rotary vane, to filter out the fine material and be discharged from the overflow pipe. Features; Technical data; Application;
