Vibration mill and method for milling a milling material

A method for milling a milling material by means of a vibration mill in at least two milling beakers which perform oscillations in a horizontal position, wherein the vibration mill comprises a multi-part pendulum drive having an eccentric shaft rotatably mounted about a vertical eccentric axis, two rockers for holding the milling beakers, which rockers are each mounted about a respective vertical oscillation axis so as to be capable of oscillation and are connected via couplers to the eccentric shaft, and a motor unit coupled with the eccentric shaft as a drive for the eccentric shaft;

• wherein a rotary movement of the eccentric shaft is converted via the couplers into oscillating movements of the rockers;
• wherein the motor unit and/or at least one balancing weight of the pendulum drive is so displaced and/or adjusted that a center of gravity of the pendulum drive in a horizontal center of gravity plane is at least substantially equidistant from both oscillation axes;
• and
• wherein the center of gravity of the pendulum drive is located between a vertical center of gravity axis of the motor unit and the vertical eccentric axis.
