【Abstract】 The reasons of high consumption of dense medium in Guobei coal preparation plant were analyzed from aspects of management and technology. The main reasons are the transshipment of medium, the unevenness of cyclone feeding and the low sculting efficiency of curved screen, et al. In order to reduce dense medium consumption effectively, a lot of measures are taken to transform the plant, like strengthening medium management, transformingcoal separation device of feeding belt, and optimizing sculting efficiency of curved screen. brought considerable economic benefit.更多还原
