Do not run the mill dry. When product has almost run through, open the rolls and disengage the apron. Do not wear loose articles of clothing or any accessories that can get caught in the rolls. Roll journals are equipped with ball or roller bearings. It is good practice to lubricate the bearings on a monthly basis.

Roller milling is one of many methods used to produce flour. It is a process used to separate the anatomical parts of grain kernels —like the bran, aleurone layers, germ and endosperm—and grind them down into fine flour particles. The flour is then used in the production of bakery products, pasta, breakfast cereals, pet foods and snacks. 1.
