cement grinding mill ventilation

Identify and resolve mill ventilation problems in cement

There is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer. In fact, this simply leads to over-grinding and increased void filling, which reduces grinding efficiency and often leads to a wider particle side distribution, increased separator rejects and eventual reduced mill output.

INFLUENCE OF MILL VENTILATION ON GRINDING

By ventilation of mills, ground material is drawn out from the mill with the ventilation air, the material remaining in the mill thus becoming coarser, which improves grinding economy. In fully air-swept mills, the strong ventilation may cause internal separation, which is of great importance to the grinding.
