Nov 01, 2007· Classification efficiency was also improved by 40% over the single stage unit. The imperfection and alpha values were typically in the range of 0.40 and 2.8, respectively. The classification partitioning achieved on coal and mineral matter separately revealed that the performance achieved specifically on the ultrafine coal particles was very good.
Ultrafine Gravity-Based Circuit Requirement To produce an acceptable ultrafine clean coal product from a gravity-based system, the high clay slimes must be removed. Unfortunately, the slimes tend to report with the water in classification systems. When water recovery is restricted, density effects results in the loss of coal to the slime stream.
