It’s depend on a lot of parameters. But you can calculate specific energy(unit kW/kg e.g. 0.05kW/Kg) to know which mill better. The low specific energy will means more capacity for a mill with stock motor power. And you can adjust your process to get lower specific energy if you can do some test. Then you can get better capacity.
10-12-2019· The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the “new type of high fineness cement ball mill” and “open flow high fineness cement ball mill”.
