Cement Mill Ventilation

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 overgrinding 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
