Energy considerations in compressive and impact crushing ...

2008-08-01  But in a mine, the cost and energy consumption associated with fine grinding are considerably larger than those associated with the compressive crushing. This difference in cost and energy consumption has essentially two explanations. As the particle size is reduced, the specific surface area increases.

Capacities and performance characteristics of jaw crushers

From Eqs. (1), (2) and (4), the volumetric capacity of a jaw crusher can be written as: Vh = 60N x w(S+T)/2 DT/[G-(S+T)] (5) at low speeds, and Vh = 60N x w(S+T)/2 450 g/N2 (6) = 2.645 x 105 (S+T/2)/N
