摘　　要：为了解决潘一选煤厂浮选入料脱泥池溢流量人工手动调节存在滞后性和精度低的问题,针对生产现场实际情况,制定自动化改造方案并予以实施。生产实践表明:在新系统投入应用后,浮选入料脱泥池溢流量的稳定性提高,有利于分级和脱泥作用的发挥,且能较好地解决脱泥池溢流量与浮选入料泵流量之间的不平衡问题,满足浮选作业的特殊要求。The overflow rate of the flotation feed desliming pond was originally under manual control-a control made with low accuracy and lagging trouble. In the light of the specific operating conditions,a technical renovation scheme is worked out and put into practice. Practice shows that the application of the automated control system can meet the specific requirement of the flotation circuit for its capability to maintain higher stability of overflow rate of desliming pond,give full scope to sizing and desliming effects,and keep the overflow rate of desliming pond and flotation feed pump flowrate well balanced.
