Ground particles discharged by gravity from bottom roll pair's roll gap. More about the rolls. Common roll diameters are from 6 to 10 inches, and roll lengths — which vary with the roll diameter to ensure that the roll will be mechanically robust — are from 8 to 52 inches. Longer rolls provide greater grinding capacity.
