The ball mills are often applied in mineral processing, they are e.g. an important part of the cement industry. A key factor, which influences the milling process, is the granular flow of grinding media. The flow determines: energy consumption, time of milling and capacity; thus there is a need to describe the phenomenon. The discrete element method - DEM is a computational method, which allows to simulation of the granular flow, thus it has been applied in this article. The received results of simulation have been compared with experimental results.
