The rolling process is a metalforming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is forming. Using this process, we can reduce the thickness of the metal workpiece.

Principle The differential speed and the narrow space between the rollers develop high shear over the material. Triple Roller Mill shear causes the crushing of aggregates, and particles and also distributes the drug uniformly throughout the semisolid base. Construction The construction of a triple roller mill is shown in Figure.
