Oct 01, 2020 Furthermore, the spiral classifier and the hydrocyclone displayed low performances during the classification process. The 50% passing sizes of the spiral classifier reached 317 μ m for U/F, which is substantially higher than the corresponding values of 51 μ m for the feed and 45 μ m for O/F. For the hydrocyclone, the 50% passing sizes of the ...

The basic structure, classification principle and low efficiency of the traditional spiral classifier were analyzed. The trial industrial comparative experiment was carried out by using φ300×4500 spiral classifier with the two-sided overflow and the port side overflow at the same parameter.
