Two Roll Mill. Applicatoins:-Two-roll mills function by shear created as the two rolls rotate at different speeds (friction ratio). This ratio of roll speeds is variable and is set dependent on the particular type of compound. The higher the friction ratio, the greater the generated shear and intensity of mixing. Specification:

— So if one gear has 60 teeth and another has 20, the gear ratio when these two gears are connected together is 3:1. They make it so that slight imperfections in the actual diameter and circumference of two gears don't matter. The gear ratio is controlled by the number of teeth even if the diameters are a bit off.
