  • Rolling of Metals: Process and Principles (With Diagram)

    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.GEAPS 600: Overview of Milling Principles GEAPS,Lecture 7 Part II Roller Mills Lecture 7 will expand on the discussion of the roller mill design features by describing what features are important in the reduction system.
