Most smock mills are eight sided although this can vary from six to 12. Tower mills are further improvements on smock mills. They have a rotating cap and permanent body, but this body is made of or stone. This fact makes it possible for the towers to be rounded. A round structure allows for even larger and taller towers.

These properties also offer clues as to the structure of metals. As with all elements, metals are composed of atoms. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing

Working Principle of Rolling Process: The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.
