Grinding Aids Materials

Grinding aids reduce the adhesion forces between particles without a negative impact on the stability of the material bed and fluidisation. 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.
