Advantages and Disadvantages of Particle Size
2020-2-9 · Rolls may operate at differential speeds depending on the task the mill is called to perform. Cracking, crimping and flaking use lower roll (peripheral) speeds - 1,000 Ft/min (5 M/sec) up to 2,200 Ft/min (11 M/sec) and no roll speed differentials. Mills used to grind will operate with higher roll speeds - 1,500 Ft/min (7.5 M/sec) up to 3,000 Ft ...
