| Abstract: | Crusher is the most common concentrator equipment and has very poor working condition, for example, workload volatile, the impact of severe crushing process. The conventional hydraulic protection system is through the point of contact pressure gauge to monitor oil pressure, resulting in a lot of misuse affecting the work process. In this paper, PLC is used to monitor the hydraulic overload protection system to improve the accuracy of protection ac- tion. |
