Overcoming Crushing Challenges to Improve Robustness and Efficiency

Andrew Hobbs, Head of Simulation and Modeling at Astec Industries presents at Altair's 2024 UK ATC conference.

Aggregate crushing is an essential step in the process of producing the raw materials needed in infrastructure and construction. Some crusher designs such as jaw crushers have existed for over one hundred years. Effective crushing equipment design must balance product throughput, energy consumption, and wear. Simulation offers the potential to better understand and optimize these long-standing designs to produce a more robust and efficient jaw crusher. In this study we leverage Altair EDEM and EDEM coupled to MotionView for MBD to investigate the effect of the moving jaw kinematics on crushing performance and energy input. Using a modified version of the Tavares breakage model to ensure repeatability the kinematics of the moving jaw were parameterized using HyperStudy to automate the creation and solve of a DOE, and the results were analyzed to identify an optimum configuration.
