Grinding is a good example where the energy dissipation during the impacts affects the process performance. In tumbling ball mills, the grinding media (steel balls) and the material to be grinding are lifted by the drum inner wall movement reaching a certain high and falling down (cataracting) on the surface of charge (Machado et al. 2016).Web

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.Web
