WhatsApp: +86 18838072829Historically there has been three basic ways of grinding ore, hammer mills, rolls, or wet tumbling mills. Hammer mills and rolls are not used that often and then usually only for special applications as in lab work or chemical preparation. The type of mill that is used for grinding ore in a modern concentrator is the wet tumbling mill.
WhatsApp: +86 18838072829Abstract. The discrete element method (DEM) is a proven numerical technique for modelling the multibody collision behavior of particulate systems. This method is used here to study the motion of ball charge in tumbling mills. To get meaningful results, it is essential that the parameters involved in the model be carefully determined.
