called the roll speed ratio (or roll speed differential). For instance, if one roll rotates at 1,000 rpm and the other at 500 rpm, the roll speed ratio is 2:1 (1,000/500). More shear — and thus a larger roll speed ratio — is required to crush less friable particles. Running the rolls at the ideal roll
