Page 4: Introduction
BM-400/BM-450 Mixer/Mill 1.0 INTRODUCTION Cole-Parmer Mixer/Mills are a variant of the ball mill or jar mill, which grinds samples by placing them in a container along with one or more grinding balls, and imparting motion to the container. Generally the containers and grinding balls are made from the same material. As the container is moved, the kinetic force is transferred to the grinding balls causing them to move independently, into each other and against the container wall, grinding the sample. -
