2016-1-1 · 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.
2010-5-14 · Bond’s law. Bond postulated that work required to form particles of size Dp from very large feed is proportional to the square root of the surface-to-volume ratio of the product, Sp/Vp.
