The effect of electric force became prominent with the decrease of particle size. Chen and Honaker [80] studied dry separation of coal-silica mixture by using a rotary tribo-electrostatic separator. Sizes of both coal and silica particles were chosen at a narrow size range between 150 μm and 1 mm for stable unipolar charging characteristic.
ABSTRACT In this study, the rotary triboelectrification separation technology is applied to the separation of macerals for low rank coal, which has not been studied by previous researchers. The effects of air humidity and temperature on permittivity and specific-charge were tested to ensure that vitrinite and inertinite were effectively separated under …
Although drum separators have large sinks capacities and are inherently more suited to the treatment of metallic ores, where the sinks product is normally 60–80% of the feed, they are common in coal processing, where the sinks product is only 5–20% of the feed, because of their simplicity, reliability, and relatively small maintenance needs.
