closed circuit grinding ball mill. The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier the flow sheet is shown in Fig 25 and the actual layout in Fig 9 This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required.
New continuous and discrete mathematical models are elaborated for describing some types of closed-circuit grinding mill-classifier systems. Based on the discrete model computer simulation is also developed for investigation of grinding processes. The starting point in developing the model is the continuous grinding equation for the open-circuit grinding which is a partial integro-differential ...
