    Jan 01 2016 · Roll Crusher Geometry. Simplifying Equation (6.1) the radius of the roll is given by (6.2) R = L − d cos θ 2 (cos θ − 1) Equation (6.2) 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.
