Rolling is the most important metal forming process. More than 95% of ferrous and nonferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. and Fig.

The table roller mill is a robust and reliable mill suitable for processing mediumhard mineral raw materials. For many years, however, the fineness range of these mills was limited to end products not finer than d 97 = 40 60 µm. This was attributed on one hand due to the lack of a modern classifying stage and on the other

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.

The principle of roller mill is based on the crushing or compressing mechanism which is created by stress. It crushes and grinds big materials into tiny particles. Pharmaceuticals need to be small and consistent for more be effectivity. So, this mill controls the size and uniformity of the particles.
