cement grinding mill ventilation

Identify and resolve mill ventilation problems in cement

May 09, 2019· 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.

Measuring ball mill ventilation GCP Applied Technologies

May 09, 2019· Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.

INFLUENCE OF MILL VENTILATION ON GRINDING EFFICIENCY

The reason why closed-circuit grinding is far more economical than open-circuit grinding is the coarser material in the closed-circuit grinding mill. 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.
