ABSTRACT:
A laboratory vibration grinding mill comprising a circular oscillating drive that operates in at least two dimensions, at least one support, and a respective elongated grinding bowl held in each support. The grinding bowl has a filling of grinding bodies and is provided with frontal grinding bowl bases. The support for a grinding bowl is configured such that a longitudinal axis of the grinding bowl forms an angle of less than 90° with a plane of movement of the circular oscillating drive such that due to movement paths of the grinding bodies in the grinding bowl caused by the inclined position of the grinding bowl relative to the plane of movement of the circular oscillating drive, the frontal grinding bowl bases are incorporated into a size-reduction process as abutment and grinding surfaces.
