Roller Mill Air Meterial Ratio

Ideally, you should observe roller mill tests of your material in the mill manufacturer’s plant. The tests will help determine not only the best roll surface, roll speed ratio, and roll gap for your application, but the ideal num-ber of roll pairs, motor size, feeding device, and other op-tions. Expect the tests to demonstrate that the roller
