Design of Control System for the Ball Mill

Article Preview

Abstract:

The Ball Mill System (BMS) is a strongly coupled MIMO system,in order to implement a long-term automatic operation of the BMS effectively,and improve the automation level and efficiency, the paper present the overall design of the system,the control system is composed of Siemens SIMATIC S7-400PLCS7-200PLC,the PROFIBUS DP protocol and MPI protocol are both employed to setup a DCS networking.This control system has been running steadily and efficiently and the operation record showed that a satisfying control result is obtained.InroductionBall mill system is an important link in the modern industrial production,its the main boiler auxiliary equipment.Its work directly affecting the operation of the boiler, the system in the chemical plant, thermal power plant, ore mining and smelting has a wide range of applications, and ball mill system is a large power consumption. The Electricity consumption accounted for factorys power 15%~25%. Safe and economical operation of ball mill system not only directly affects the security and reliability of the generator at the plant and also is the important way of energy saving and consumption reducing[.
