The kinematics of the single-toggle crusher has been modelled by Oduori et al. (2015). An energy efficiency study was performed by Legendre and Zevenhoven (2014). In their study, energy was estimated with the Bond work index, and an on-line optimization algorithm was used to increase the efficiency of a laboratory crusher.

Based on a large number of tests, Bond introduced a working index or comminution parameter that represents the resistance of the material to crushing and grinding. Characterization of rocks for selection of crusher can be done in different ways, and the most commonly used is Bond work index (Tavares and Carvalho 2007).
