破碎是选矿工业流程中的关键环节。破碎过程中要求机腔料位稳定,以提高处理量并进而提高整个破碎流程的效率。文章给出了控制系统的实现,完整阐述了控制器选择、设备选型、硬件搭建、软件编程、调试与运行等诸多问题,实现了给矿自动控制系统的设计目标。文中所给出的控制算法和程序可直接或稍加修改即可应用于生产实际过程中。 Crushing is a key part of the beneficiation process. The crushing process requires that the cavity level be stable to increase the throughput and thus the efficiency of the entire crushing process. The article gives the realization of the control system, and fully explains many problems such as controller selection, equipment selection, hardware construction, software programming, debugging and operation, and realizes the design goal of automatic control system for mine. The control algorithms and programs given in this paper can be applied directly or slightly to the actual process of production.
