Abstract: There are two problems in the grinding process of mill，the one is that it is difficult to realize automatic control of mill load and the other is that there is the disadvantages of OPC technology data transmission.A monitoring system based on C# is designed by using VS programming software.According to the actual production needs and the requirements of the monitoring system，the monitoring system is designed in the following functions as the running state display of the equipment operation data，the drawing curve of mill,four kinds of control mode of manual，automatic，expert and optimization，the function of editing and operating menu module under human-computer interaction，and the operational data storage.At the same time,the serial communication technology owned by C# is adopted to realize the data transmission between the mill controller and the monitoring computer.The running results show that the system can meet the requirement of automatic control of mill，and has the advantages of low development cost，strong reliability and flexible control mode.
