原煤中煤泥含量的增加超出了现有浮选设备和过滤设备的处理能力时,其结果只有一部分煤泥得到处理,使煤泥在选煤厂的煤泥水系统中多次循环并累积。改进煤泥水系统是挖掘选煤工艺潜力、使其进一步完善的途径之一。顿涅茨克选煤联合公司的《丘玛科夫斯卡娅》中央选煤厂于1935年投产。该厂目前入选灰分为38.6％的原煤,能力570t/h。精煤品种为贪煤,作配焦和动力煤用。重力分选车间的筛下水[不包括第一段(主选)和第二段(再选)精煤离心脱水机的离心液]
When the increase of coal slime content in raw coal exceeds the capacity of existing flotation equipment and filtration equipment, only a part of the slime is treated as a result, and the slime is circulated and accumulated many times in the slime water system of the coal preparation plant. Improving coal slime water system is one of the ways to tap the potential of coal preparation technology and further improve it. Donetsk Coal Preparation Joint Company “Chumakovskaya” Central Coal Preparation Plant was put into operation in 1935. The plant currently selected for the 38.6% ash raw coal, the ability of 570t / h. Coal varieties for the greasy coal, with coal and thermal coal.
