Abstract:  In order to solve the problems that the process flows of cement loading machine and stackers interiorly still depends on artificially labor and the working conditions are poor presently, the automatic control technology was investigated. After the analysis of the process flows of cement loading machine and stackers, an automatic control system was developed  by Siemens S7200 PLC,  the hardware system and software system were designed,  the automatization of equipment was  implemented  ultimately. This system has simple operation, reliable control, convenient maintenance, high performancetoprice and has strong market competitiveness. The experimental results show that the system reduces manual control in the production process, and raises the production efficiency and safety coefficient consequently.
