摘要
本文介绍基于双光子吸收原理的一种在线自动识别与分拣煤矸石系统。它适用于粒度级别为50～150mm 的矿样,传送带速为≤1m/s,年处理量为120万 t 的矿井。实验表明,分选的准确率可达90%以上.原则上本方法也可适用于粒度级别为20～50mm 的矿样。
This paper introduces an on-line system of automatic discriminating and separating the gangue from coal based on the principle of double photon absorptiometry.It is applicable to a coal pit with annual output of 1.2× 10~6 t,The size of sample ore is 50～150 mm,and the conveyer speed is less than 1 m/s.During the test run it is shown that the accuracy of separating gangue is better then 90%.In principle,this separator is also suitable for the sample ore of 20～50 mm size.
