AI Technical Summary

Technical Problem

Traditional vibration mill equipment has difficulty in real-time monitoring of the impact force of the grinding medium inside the grinding barrel, resulting in energy waste, grinding medium wear and powder contamination during the crushing process. In addition, the crushing efficiency is low and cannot be precisely controlled.

Method used

Multiple dynamic force sensors are installed axially on the inner wall of the grinding cylinder. The signals are transmitted to the multi-channel charge amplifier and high-speed acquisition card through connecting lines to monitor the impact force of the grinding medium in real time. The vibration parameters are adjusted in combination with variable stiffness springs and frequency converters to achieve precise control.

Benefits of technology

It realizes the real-time monitoring and dynamic regulation of the impact force of the grinding medium inside the grinding cylinder, optimizes the crushing efficiency, reduces the grinding medium loss and energy waste, and improves the crushing effect.
