Laboratotypulverizer is a disc type grinder, designed to grind virtually any material to produce a fine mesh sample in one operation. It is a self contained grinder, with a rotary disc, having a planatory movement in a vertical plane. This feature gives added life to the moving parts and produces a sample of uniform finenes.
