Crushing, Grinding and Reduction in Flour Milling Miller

Grinding capacity is calculated according to the factory’s capacity. Crushing roller mill rolls should be up to approximately 40 percent of the total roller mill length, Reduction (liso) roller mill rolls are up to 60 percent of the total roller mill lenght. The average lenght of the roller mill is based on the account of12mm / 100kg /24 hours.
