跳汰机的可控硅排矸技术近年来已在我国一些洗煤厂中应用,我厂于1972年初在主洗机一段安装一台试生产,经过多年实践,认为可控硅元件比较可靠,反应也较灵敏,但山于我厂入洗原煤量和矸石量变化较大,检测部分采用筛下水液位变化反映床层情况不太适用。因为筛下水液位 In recent years, the jig refueling technology of jig has been applied in some coal washing plants in China. At the beginning of 1972, our factory installed a pilot production in the main washing machine section. After many years of practice, the controllable silicon components were considered as reliable and the reaction But also more sensitive, but the mountain in our plant into the washing of coal and gangue volume changes, the detection part of the screen using sub-level changes reflect the bed is not applicable. Because the sieve water level
