What are the fundamentals of conching and what is the best ...

Roll Mills and Ball Mills. Roll mill do not perform any conching action. Because the conventional product coming out of a roll mill is a powder, this is where the concept of dry conching (before the addition of cocoa butter) may have originated. Ball mills generically do not perform conching.

Metal rolling oils | Energy Technologies

Metal rolling is the process of stretching a piece of sheet metal to a certain thickness by increasing its length. Friction control between metal rolls is critical: low friction is desirable in some places, but if friction is too low in other contact areas it can cause the rolls not to flatten the metal effectively, creating pits and smears.

Rolling (metalworking) - Wikipedia

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, England.In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved …
