摘　　要：为了解决潘一选煤厂浮选系统人工加药存在的问题,在制定改造方案的基础上,对其进行自动化改造。介绍了浮选自动加药控制系统的控制原理、系统结构、系统功能,并分析了其在该选煤厂的应用效果。生产实践表明:该系统投入应用后,工人劳动强度降低,浮选效果明显改善;浮选精煤灰分比较稳定,浮选精煤产率提高了1.01个百分点,干煤泥药剂消耗总量下降了0.13 kg/t,经济成效显著。In order to solve the problems encountered by the plant in the use of artificial flotation reagent dosing system,work is made on its transformation into an automatically- operated version,on the basis of the well- conceived renovation scheme. Following a description of the working principle,structural design and functions of the automated dosing control system,an analysis is made in the paper of the results obtained through the application of the system. Practice indicates that the use of the system has led to reduced labor intensity,noticeably improved flotation performance,higher stability of flotation concentrate ash,an increase of the yield of flotation concentration by 1. 01 percentage points,and a drop of consumption reagent by 0. 13 kg / t（ dry fine coal）,bringing in,therefore,remarkable economic benefit for the plant.
