Mill feed rate is thought to influence consumption of grinding media in that it influences the wear mechanisms acting on the media. At low feed rates, impact forces are considered to dominate over abrasion (Gates et al., 2007) and Howat and Vermeulen (1988) have observed that at low feed rates, when the residence time of particles within the mill …Web

A considerable volume of work exists in the literature examining the electrochemical interactions between grinding media and sulfide minerals. Broadly, most sulfide minerals are more noble than forged steel grinding media used during comminution, therefore a galvanic couple between the media and the sulfide mineral(s) exists, which increases …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
