Abstract：For grinding process with characteristics such as nonlinear,time-varying,grind size can't be measured directly online,integrated automation technology,composed of and process control system and manufacturing execution system,is put forward.Through Ether Net and Control Net,the system is exploited based on Control Logix and RSview32,and it applied to grinding process of a concentrator.Ultimately,optimal control,operation and management is realized in grinding processes,and remarkable application result is achieved.
