Abstract:
The invention shows and describes a vibration mill for at least two grinding beakers performing vibrations in the horizontal position, with at least one multi-part pendulum drive, wherein the pendulum drive has at least one eccentric shaft mounted to rotate about a vertical eccentric axis, and at least two rockers each mounted so as to be capable of vibrating about a vertical vibration axis and connected by means of couplers to the eccentric shaft, said rockers holding the grinding beakers. The pendulum drive further has a motor unit coupled to the eccentric shaft as a drive for the eccentric shaft and optionally further components, wherein a rotary movement of the eccentric shaft via the couplers can be converted into a vibrating movement of the rockers. According to the invention, the centre of gravity of the pendulum drive in a horizontal centre of gravity plane is substantially equidistant from both vibration axes.
