DEM was used then by Cleary and Sinnott (2014) to simulate five types of crushers, and estimated power draw, product size, and throughput were estimated. Qusit and Evertsson (2016) predicted the particle size distribution and power draw of the cone crusher based on DEM. Tavares (2017) reviewed using DEM in ball mill.
