Ventilation systems can absorb up to 20% of the total heat discharged by the ball mill. Improving the ventilation system allows more cool air to enter the ball mill, lowering the inside temperature gradually. Ball mills, on the other hand, have a significant advantage in terms of product fineness. As a result, many ball mill grinders ...

It should be noted that enhancing the ventilation in the ball mill grinder can reduce the material temperature, but the ventilation in the ball mill is not only limited by system resistance, air lock, air leak, but also restricted by product fineness. Excessive air volume will make the grinding effect of the ball mill grinder worse.

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.

It is crucial to point out that shell protection is only one function of the mill liner. It also needs to optimise the grinding process. Clinker grain sizes depend on pre crusher settings but are in some cases still up to 50mm when fed to the ball mill and therefore, it is necessary to adjust the grinding tools accordingly.
