One potential method is strengthening the internal and external ventilation of the grinder. Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.

A simple check for the degree of false air is to compare the mill cement exit temperature with the mill gas exit temperature. As the cement and gas leave through the mill exit at the same temperature in a wellsealed system, the difference in these two temperatures will be only a few degrees. If the temperature difference is in excess of 10°C ...
