Review Grinding Aids t - J-STAGE Home

In dry grinding in ball mills, the loading time is less than 1 second and cracks will propagate faster than 10·1 em/sec. Therefore, one must conclude that for dry grinding neither adsorption nor chemical reaction can influence crack propagation in a comminution mill. For wet grinding, however, crack velocities must be

Progress with Grinding Aids for Vertical Roller Mills - Sika

In ball mills, where the grinding time is longer than in a VRM, excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill. In contrast to ball mills, VRMs have a very high internal circulation, a short mill retention time and a huge number of classifying steps that carry the welldispersed fines out of the mill system.
