摘要
简述了老石旦选煤厂存在的设备老化严重、分选效率低等问题;分析了原煤煤质及采用S-3GHMC440/360/260型超级三产品重介质旋流器分选工艺的技改工程方案和改造后的经济效益;从分选数量效率、可能偏差等方面分析了改造系统的工艺指标。
The paper briefly describes the problems existing in LaoShidan coal preparation plant,such as serious aging of equipment and low separation efficiency.The quality of raw coal and the technical modification project of S-3GHMC440/360/260 super three-product heavy medium cyclone separation process and the economic benefit after modification are analyzed.The process indexes of the system were analyzed from the aspects of sorting quantity efficiency and possible deviation.
