曙光煤矿块煤TDS智能干选的可行性分析

Feasibility analysis of lump coal TDS intelligent dry coal preparation in Shuguang Coal Mine

结合曙光煤矿实际生产中试验入料200mm^40mm块原煤的性质及其试验分选结果,介绍了TDS智能干选机基本原理、特点及应用领域,从技术及经济效益方面分析煤矿200 mm^40mm块煤预排矸项目,并改造曙光煤矿现有的动筛系统,新增TDS块煤预排矸系统,对200 mm^40mm块煤进行有效分选并回收块原煤,同时新增滚轴筛以提高原煤黏湿情况下的筛分效率。

Combining with the raw coal quality and separation results of experimental feeding material （200--40 mm lump coal） in actual production of Shuguang coal mine, the basic principles, characteristics and application field of TDS intelligent dry preparation machine were demonstrated, from aspects of technology and economic profits, the 200 -- 40 mm lump coal beforehand gangue discharging project was analyzed, and the existing moving screen system was transformed as well, the additional TDS lump coal beforehand gangue discharging system was established, the efficient separation for 200--40 mm lump coal and the recovery of lump raw coal were done, at the same time, roller screen was added to improve the screening efficiency when the raw coal was wet.
