司马选煤厂块煤智能干选改造实践

Practice of Intelligent Dry Separation Transformation of Lump Coal in Sima Coal Preparation Plant

针对司马选煤厂300~50 mm块原煤动筛跳汰分选存在分选精度低、矸石带煤率高等问题,从选择块煤排矸方法、改造工艺流程、主要设备选型等方面探究了块煤智能干选改造策略。生产实践表明,块煤智能干选改造降低了矸石带煤率,且节省了人力、物力,具备良好的经济效益和社会效益。

In view of the problems of low separation accuracy and high gangue carrying coal rate in the 300-50 mm block raw coal moving screen jigging separation of Sima Coal Preparation Plant,the transformation strategy of intelligent dry separation of lump coal is explored from the aspects of selection of lump coal gangue removal method,transformation processflow and main equipment selection.The production practice shows that the intelligent dry separation transformation of lump coal reduces the rate of gangue carrying coal,saves manpower and material resources,and has good economic and social benefits.
