In 1950, the American Fred Chester Bond put forward the "crack theory," which believed that "the power consumption of the crushing process is proportional to the length of the cracks formed during the crushing process." The theory became the widely used "third theory" of crushing and is suitable for medium and fine crushing.
The power consumption by a crusher is calculated by summing all the energy dissipation components from the contact model in Eqs. (2) and (3) for all collisions (both between particles and between particles and the crusher liner). When the load within the crusher and the flow are at steady state the rate of power draw by the crusher and …
Power Consumption of Gyratory and Cone Crushers. To compute the power consumption of gyratory crushers, knowledge of the ore work index and crusher capacity is necessary.

Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.
