  • Effects of Ball Size on the Grinding Behavior of Talc

    Effects of Ball Size on the Grinding Behavior of Talc

    The effect of the ball size for planetary ball milling on the grinding rate and behavior of talc is investigated with a varying ball size (2, 1, and 0.1 mm). Changes in the agglomeration characteristics of mechanochemical talc and the relationship with the ball size is also investigated.

  • Effect of ball size and powder loading on the milling

    Effect of ball size and powder loading on the milling

    Dec 01, 2013 In this figure, the positive influence of the smaller ball size on the milling efficiency is drawn by an arbitrary negative slope with ball size rather than the dependency of d −3, because the dependency of d −3 is valid only in a stationary state of ball packing while the actual ball milling is a dynamic event taking place under the presence of the powder slurry existing between the balls. Actually the increased number of contact points by the reduced ball size …
