Optimal coal processing route for the 3 x 0.5 mm size . - SAIMMWith the introduction of large diameter cyclones, the aperture sizes of des screens have progressively increased to about. 3 mm in the belief that the larger cyclones are not able to effectively beneficiate coal that has a particle size below the 'breakaway' size. The efficiency of separation in the large dense- medium.dense media cyclone break away size,Dense Medium Cyclones - Taylor & Francis Onlinedifferent process variables such as cyclone dimensions, feed pressure, medium properties and feed rates are not yet fully understood. Some of these aspects are discussed in the paper. Keywords Dense medium; Cyclone; Coal; Breakaway size; Medium; Feed pressure; Efficiency. Introduction.

Table 3 – Dense medium cyclone separation fault finding Observation Possible problem Action Feed to the .. The breakaway size for a specific cyclone diameter is calculated by: db = (6 x Ø1.64 ) x 10-5 (3) Figure 5 shows the breakaway size for different.
