Coal preparation process starts with crushing and screening of freshly mined coal, which removes some of the noncoal material. Washing is actually the process of separation of noncoal materials. Washing or cleaning of coal represents the most important step of coal preparation.
Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravitybased separation performance for 100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two coal preparation plants use spirals in this application.
