Study of two volcanic materials and the grinding effect on
Figure 1 shows the grinding ability of volcanic materials. The graph depicts that PVM tends to reduce its size at shorter grinding time. Although PVM begins with a greater particle size (57.6 ym), compared to TVM (34.5pm) this can be clearly observed after 90 minutes of grinding by the bails mill, as PVM reaches the average particle size of TVM.
