Abstract The paper focusses on improving the energy utilization of a cement grinding circuit by changing the flow sheet of the process. The circuit was comprised of ball mill, static classifier and dynamic classifier and in the current flow sheet the fine product of static classifier is sent to feed stream of dynamic classifier. However, it was experimentally proved that sending static fine to ...
Nov 16, 2020 The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is 10.13. The result shows that the horizontal ball mill able to grind the calcium carbonate to a size of smaller than 100 mesh 149 m.
