International Journal of Coal Preparation and Utilization

ABSTRACTIn this study, the performance of a continuous air dense medium fluidized bed (ADMFB) separator is investigated for coal beneficiation. The full factorial experimental design method is used to study the effect of superficial air velocity (U), bed length (T), and bed height (H) on the cleancoal ash content, organic material recovery, and overall system separation efficiency.

Prediction of the position of coal particles in an air ...

An air dense medium fluidized bed separator (ADMFBS) is used for dry beneficiation of coal using ultrafine magnetite particles as a pseudofluid medium. In this process, the coal particle gains additional weight due to coating on its surface and deposition at dead zone area by fine magnetite particles.
