The Distributed Control System (DCS) was adopted to design and optimize the entire process of the Zhuzailing Aggregate Plant, including crushing, screening, sand making, and water circulation control, through hardware redundancy configuration, integration of Modbus communication protocol, and implementation of advanced control algorithms. The application effects in aspects such as material balance, equipment monitoring, and energy consumption management were analyzed. The actual application results show that this system significantly shortens the equipment start-stop time, reduces no-load energy consumption by 15%. The failure shutdown rate decreased by 30%, and the spare parts inventory turnover rate was optimized by 35%. The water consumption per ton of aggregate reduced from 3.2 m3 to 2.56 m3, saving 250,000 tons of water annually. The enterprise energy consumption achieved an 18% reduction comprehensively. The overall life cycle of equipment was extended by 3 to 5 years, resolving technical challenges such as signal transmission and circuit operation in high-dust environments, lightning strikes, or power fluctuations, thereby providing a technical reference for the intelligent transformation of industries such as aggregate processing.
