Secondary Tertiary Crushing Circuits

Jul 24, 2015  This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

Roll Crushers - ScienceDirect

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.
