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.
Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

Working Principle of Coal Grinding Mill. Coal grinding mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment of pulverized coal furnace. The ball mill is a horizontal cylindrical rotating device driven by external gears. Mate rial from the feed device enters the mill evenly through the feed ...
The following is the working principle drawing of symmetrical 3 roll bending machine. Driven roller Ⅱ, Ⅲ is driven by motor and reducer, which rotates in the same direction at the same speed (or in the opposite direction). Because of the friction between the roller and the plate, the plate is driven forward and the roller is rotated.
Attrition mills: Roller mills. GRINDERS WORKING PRINCIPLE OF ATTRITION MILLS Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces.
