The ventilation effect of the ball mill is roughly in two aspects: one is to discharge the fine powder in the mill in time, so as not to affect the grinding efficiency; second, to reduce the temperature in the mill to avoid the grate of the gypsum dewatering tail bin paste ball.

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.

MILL VENTILATION MEASUREMENT The ventilation of a ball mill is extremely important and this for several reasons: removal of the very fine particles, dedusting of the internal equipment, keeping an acceptable temperature, avoiding coating on balls and/or linings, better drying of the material for the raw mills.
Mill ventilation: The amount of air that is circulating in the mill can also have an impact on the output. Good ventilation will help to keep the mill cool and prevent material from clogging.
The hourly output of the ball mill is greatly affected by the feed rate. According to a large of reference data, the mainreason that the feed rate and ventilation of the ball mill is whether the grinding mill feed inlet design is reasonable. The feed inlet in the design of the oldstyle ball mill is usually installed
Mill ventilation: Ensure that the mill is properly ventilated to maintain a cool operating temperature, which will help to improve grinding efficiency and extend the life of the grinding media.
One of the most critical variables in the cement ball mills is ventilation. A mixture of hot and recycled air would deliver and dry the powder in a cement ball mill as a pulverizing system. Thus, ventilation in this system can have a significant effect on the production process.

Nowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and ...
the mill partitions, feed rate, the hardness of the feed material, and ball sizes in the mill compartments. Understanding the relationships between these variables from the grinding units can play an essential role in efficiently operating cement production lines [35]. One of the most critical variables in the cement ball mills is ventilation.
Therefore, the ventilation methods of many ball mill grinders are restricted by that fineness. Air vents must be no larger than the small material you are attempting to create. Additional issues with proper ventilation are created by system resistance, air locks, and other air leaks.
