一、改造前的情况 马家沟矿业公司选煤厂,是在1992年由平顶山选煤设计院设计的年入洗量为60万吨的全重介洗煤厂。其浮选系统的药剂添加一直是采用人工凭经验以调节油滴,来实现油醇的配比,操作水平仍停留在五六十年代的操作方式。由于浮选工艺过程是一个比较复杂的物理化过程,参数较多。其次,根据该厂 First, the situation before the transformation Majiagou Mining Company coal preparation plant, is designed in 1992 by the Pingdingshan Coal Preparation Design Institute of the year into the amount of 600,000 tons for the entire heavy medium washing plant. The flotation system of pharmaceutical additives has been manually adjusted by the use of oil droplets to achieve the ratio of oleyl alcohol, the level of operation is still stuck in the fifties and sixties of the mode of operation. As the flotation process is a more complex physical process, more parameters. Second, according to the plant
