Impact Crushers Modelling SlideShare

2016-2-9  2. The PFC3D models of impact crushers Impact crusher modelling has been performed using the PFC3D discrete element code. This code models the behaviour of particles, which may be enclosed within a finite volume by the non-deformable walls. The code keeps a record of individual particles and updates any contact with other particles or walls.
