The grinding media inside the jar exerts mechanical pressure on the materials, reducing them to finer particles or powders. Understanding Roller Mills. A roller mill, a form of compression mill, consists of a single, double, or triple cylindrical heavy wheel mounted horizontally that is rotated due to a motor or hand operation.
In this initial study, two aspects of the control of the roller compactor were adjusted to evaluate the effect on the resultant granulate, namely the compaction force and the roll gap. Compaction force was controlled by modifying roll settings. The roll speed and mill mesh were fixed at 2.5 rpm and 1 mm respectively.
