Roll Crusher Geometry. Simplifying Equation () the radius of the roll is given by () R = L − d cos θ 2 ( cos θ − 1) Equation () indicates that to estimate the radius R of the roll the nip angle is required. The nip angle on its part will depend on the coefficient of friction μ between the roll surface and the particle surface.
