AI Technical Summary

Technical Problem

In the existing technology, the selection of vibration frequency of vibratory feeders lacks reliable quantitative basis, which makes it easy for the feed opening to form an arch and become blocked, affecting the efficiency and safety of ore discharge. Moreover, the reliance on experience leads to a lack of in-depth research.

Method used

By reconstructing a three-dimensional model of the ore and rock particle blockage and accumulation system using CT scanning technology, the physical and mechanical properties of the particles and the characteristics of the arch structure are analyzed. The minimum vibration frequency is recorded, a quantitative relationship is established, and the selection of the ore discharge machine frequency is guided.

Benefits of technology

This study provides a theoretical basis for efficiently and accurately selecting the frequency of a vibratory ore feeder under the coupling of multiple factors, thereby improving ore feeding efficiency and mine production benefits.
