A small solid particle resting atop a vibrating fluid interface generates a field of outwardly propagating capillary waves due to its relative vertical motion. In this paper, we show that if the particle's symmetry is broken, the resultant unbalanced wave stresses enable steady selfpropulsion along the interface. Such ``capillary surfers'' interact with each other hydrodynamically at long ...

Stamp mills use a vertical crushing mechanism to break down ores, via a set of battery pads. The number of crushing pads varies between models, and those with more pads will generally come with a greater crushing capacity. Stamp mills are less sophisticated than ball mills, but affordable and effective for basic rock crushing.

The vertical vibration of a cold rolling mill as a dynamic process can mainly be expressed by the amount of change of displacement of the work rolls and strip during the rolling process. If the change is too large, it means that the vertical vibration has affected the rolling thickness at exit and surface quality. Therefore, discussing the ...
