In actual production, the size of limestones before crushing ranges from 0.5 to 1.0 m. After the crushing process, the majority of products are less than 75 mm in size and the smallest size can be inferior to 5 mm. The size of the smallest particle is a crucial factor in determining the time step of DEM simulations.
