In grinding grain, spices, chemicals, paint, rock and other substances on rolls, the usual mode employed is what is known as the gradual reduction process, in which the grinding is performed by a successive numher of reductions, commencing with a coarsely corrugated pair of rolls for the first operation, as in flour milling, followed by a number of pairs of rolls with corrugations …
The working of a grinding machine: A grinder features an electric motor that supplies motion power to the grinding wheel using pulley and belt. For the portable grinder, the rotor is inside the grinding machine and the power switch is located beside the handle of a grinder. So, the switch must be pressed before the grinder works.
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.
