夹河煤矿洗煤厂原设计入洗能力为60万吨/年,近几年来经过技术改造,实现了跳汰机单机自动化,浮选工艺参数自动调节,全厂集中控制。入洗原煤能力逐年增长,1980年以来一直稳定在120万吨/年,比设计能力翻了一番。同时,精煤质量提高,灰份在9.5％左右;累计上交利润8188.37万 Jiahe coal washing plant was originally designed to wash capacity of 600,000 tons / year, in recent years after technological innovation, to achieve a single machine automation jig, flotation process parameters automatically adjust the whole plant centralized control. The capacity for raw coal washing has risen year by year and has been stable at 1.2 million tons / year since 1980, doubling the design capacity. At the same time, the quality of refined coal increased, ash content of about 9.5%; total profit turned 81,883,700
