城山煤矿洗煤厂煤泥浮选工艺发展方向探讨

Development of coal flotation process in Chengshan Coal Preparation Plant

通过对城山煤矿洗煤厂煤泥浮选工艺发展方向的探讨可知,影响煤泥浮选工艺效果的主要参数是浮选入料的浓度与流量及浮选药剂量和药剂配比,采用PLC可编程自动控制系统能稳定浮选入料浓度与流量,按入料干煤泥量确定浮选药剂的添加量和配比,可达到较好的浮选工艺效果。

This paper discusses the development of the slime flotation process in Chengshan Coal Preparation Plant.Then the main parameters which affect on the slime flotation process can be found： the concentration and flow rate,flotation pharmaceutical dosage and its ratio.Using the PLC programmable automatic control system,the flotation feed concentration and flow rate can be stabilized.According to the amount of feed dry slime,the flotation reagent and the ratio is determined to achieve the better results of the flotation process.
