Evan Doran. 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 …

The grinding time needed is determined by the power of the grinding equipment. In our wet grinding process, we are not aiming to reduce the size (as was already shown in Section 2.4), but simply to intensify the mixing and to keep the reaction surface clear of reaction products. The main energy consumption is in the size reduction …
