POLYCOM high

2020-11-26The grinding action of a ball mill involves a mixture of compressive and shear forces, whereas the POLYCOM imposes virtu-ally pure compressive force on the layer of material between the rolls. In comparison with the shear stress, the compression stress built up in a particle of material in a POLYCOM is almost five times higher.
