A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

In the current work the wet tumbling ball mill process is modelled by a combined threedimensional PFEMDEMFEM model. The validation is conducted by comparing numerical results with experimental measurements from grinding in an instrumented smallscale batch ball mill equipped with an accurate torque meter (Jonsén et al., 2013).

The process of model validation is performed in five steps for two different types of coal mills. Each step is described in a separate paragraph for clarity. The idea is to investigate how the model behaves when parameters change (for example due to mill wear) and how well the model describes other types of mills.
