This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

As a rule of thumb, dry grinding generally will achieve particle sizes of 35 microns. To mill to sizes below that range requires wet milling. Today, the trend clearly is to produce nanoparticles. Wet grind processing can be done in batch, continuous or circulation modes. In recent years, many paint and mill grinding.

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.
