The new technique of using ultrasonic vibration to break hard rock is still in the experimental stage, but it has significant potential for improving the efficiency of hard rock crushing. We have analyzed the mechanical properties of granite under ultrasonic vibration and the characteristics of the damage produced.

Ultrasonic vibration rock crushing technology is a new type of rock crushing method, and it can be used in hard rock drilling. By applying high-frequency cyclic load to the rock, it promotes the expansion and penetration of micro-cracks inside the rock, causing fatigue damage, reducing the rock strength, and thus improving the rock crushing ...
