2013-3-13 HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a 1.5 mio t/a cement plant.

Because the roller press and the ball mill are two separate circulate system, the whole cement grinding process is easy to operate and control. The grinding efficiency of the system is also enhanced because qualified fine powers from the roller press don’t need to be ground again by the ball mill.
