Application of the Falcon Concentrator for fine coal cleaning
1996年11月1日 Abstract. An enhanced gravity separator (EGS) commercially known as the Falcon Concentrator has been evaluated for its ability to treat fine coal. From a comparison with other EGS technologies, the magnitude of the applied centrifugal force was found to determine the overall separation performance and throughput capacity.
