洛阳矿山机器厂是我国生产大型洗煤设备的主导厂。1958至1985年已生产各种洗煤设备4035台套,基本上能满足年处理量为350万吨洗煤厂的需要。当前,国产洗煤设备的性能指标与国外先进设备相比,还存在不少差距。如跳汰分选效率,国产设备为85～90％,国外为90～95％;介质消耗,我国为1～2公斤/吨煤,国外为0.2～0.4公斤/吨煤。洗煤设备还不能满足洗煤 Luoyang Mining Machinery Factory is the leading manufacturer of large-scale coal washing equipment in China. From 1958 to 1985, a total of 4,035 sets of coal washing equipment have been produced, basically meeting the needs of 3.5 million tons annual coal washing plant. At present, the domestic coal washing equipment performance indicators compared with foreign advanced equipment, there are still many gaps. Such as the jig sorting efficiency, domestic equipment is 85 ~ 90%, foreign 90 ~ 95%; medium consumption, China is 1 ~ 2 kg / ton of coal, foreign 0.2 ~ 0.4 kg / ton of coal. Coal washing equipment can not meet the coal washing
