Effect of grinding media properties and stirrer tip speed ...
This was because the stress energy of the grinding media exceed the required amount of the breakage event, causing the energy to be dissipated from each collision and wasted energy. In addition, the distance between contours increased when the grinding time was close to the turning point, and this grinding process became inefficient.
