Abstract

Secondary cone-type crushing machines are an important part of the aggregate production process. These devices process roughly crushed material into aggregate of greater consistency and homogeneity. We apply a continuum model for granular materials (Jop et al., Nature 441:727–730, 2006) to flows of granular material in representative two-dimensional channels, applying a cyclic applied crushing stress in lieu of a moving boundary. Using finite element methods, we solve a sequence of quasi-steady fluid problems within the framework of a pressure-dependent particle size problem in time. Upon approximating output quantity and particle size, we adjust the frequency and strength of the crushing stroke to assess their impacts on the output.
