(Canon SX710 HS) was used to take pictures of the mill charge with the shutter speed of 1/500 s (about 5 fps) to observe the charge motion. Particle Flow Code 3D (PFC3D) was used for discrete element modeling of the ball mill. PFC3D modeling is based on the assumption that the individual particles (balls) can be treated as rigid bodies.

Abstract. Numerical simulation of particulate materials is required in many industrial processes with applications ranging from ball mills in mining to powder mixers in pharmaceuticals.
