The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •
