The speed of rotation of the spirals varies inversely with size. Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller …

DetailsA 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 & …

The hydraulic classifier uses sieve-plate subsidence caused by interference in the term of equipment. the body shape for the corner of the cone-shaped boxes, boxes with vertical partitions into 4-8 graded rooms. each room has an area of 200 mm*200 mm. away from the room at the end of a certain height to set the sieve. …
DetailsThe submerged spiral classifier is suitable for fine particle classification, and the classification particle size is generally less than 0.15mm. Compared with the spiral classifier, the hydrocyclone has a better classification effect when dealing with finer-grained materials (0.3-0.01mm).
DetailsThe submerged type is suitable for fine particle classification, and the overflow particle size of the classification is generally less than 0.15mm. 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 ...
