Abstract: t As a key link in the beneficiation process，the continuity and stability of the ore bin di‐ rectly affect the operation efficiency and product quality of the subsequent processes. Aiming at the prob‐ lems of frequent blocking，arching，lack of detection and unstable feeding in the process of dealing with high water content and fine-grained tin crude concentrate in a tin concentrator in Yunnan，an automatic feeding system for ore bin is designed and implemented，which integrates detection，judgment and execu‐ tion. The system adopts a three-layer control architecture of perception-decision-execution，and integrates radar level gauge，belt scale，double-position vibration dredging unloader，air gun and belt feeder to real‐ ize real-time monitoring and intelligent control of material state. The practical application shows that the system significantly improves the material balance rate and metal recovery rate，reduces the tailings grade， effectively reduces the labor intensity，and provides a technical solution for the intelligent transformation of similar mining enterprises.
