The sand compaction tests showed that at a given stress well-sorted, coarse-grained sands were more compressible and had higher velocities (Vp and Vs) than fine-grained sands when the mineralogy was similar. This can be attributed to grain crushing, where coarser grains lead to high compressibility and large grain-to-grain contact areas …

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 …

2.1 Principle of ultrasonic-assisted roller dressing. ... It is because when the dressing speed ratio q d is too large, the squeezing and crushing effect is enhanced when the roller dresses the grinding wheel, prompting poor abrasive grain contour on the grinding wheel surface, which leads to a larger surface roughness of the workpiece grinding.
