As the retention time in ball mills is 20 to 30 times greater than in vertical roller mills, the cement is exposed to the hot gas atmosphere for much longer. In addition, ball mills use much more energy than vertical roller mills in order to grind the same amount of cement, with this additional energy heating the material even further.
