System Description. Figure 2: Sessego Mill Braking System. A typical braking system consists of one or more brake calipers, mounted onto two pedestals, one each side of the mill, symmetrical about the horizontal mill centerline. Brake operation is controlled by a hydraulic power pack designed to meet each individual application.

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.
