And hence when you see a refiner mill identified as 21″ x 24″ x 36″, you simply need to decode it as Front Roll diameter is 21 inches, Rear Roll diameter is 24 inches and both the rolls have same face length of 36 inches. The Rear Rolls have a higher surface speed than the Front Rolls again a similar feature of a regular rubber mixing mill.
