The grinding jars perform oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample.
