Three types of ball-mills were employed to finely mill the prepared samples: a rotary ball mill (RBM), a stirred ball mill (SBM), and a vibratory ball mill (VBM). These mills consist of a grinding chamber filled with different milling media (balls, beads, cylinders…) set in motion by either movement of the chamber or by a rotor.

Progress with Grinding Aids for Vertical Roller Mills

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 ...
