Dec 23, 2013· From the result the size reduction increases as we increase the number of rotations of the ball milling. Meanwhile, increase in the time taken for ball milling will also increase the size reduction. From the graphs, we can see that as the size reduction increases, the particle sizes obtained will form a less steep curve in the graph.
