Operation Guide for Vertical Roller Mill in Cement Plant ...

mill indicates more internal circulations and more fines. As a re-sult of the higher ∆P mill, the mill vibration increases (8-10mm/s), which results in a good opportunity to test the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10-20min.
