Patent ID: 8042754

Claim:
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, wherein said grinding bowl has a filling of grinding bodies and is provided with frontal grinding bowl bases, and wherein said grinding bowl is configured such that a longitudinal axis of said grinding bowl forms an angle of not more than 60° with a plane of movement of said circular oscillating drive and such that a length of said grinding bowl is coordinated with a vibration intensity, which is defined by the vibration amplitude of said drive and its frequency, such that due to movement paths of said grinding bodies in said grinding bowl caused by the inclined position of said grinding bowl relative to said plane of movement of said circular oscillating drive, said frontal grinding bowl bases are incorporated into a size-reduction process as abutment and grinding surfaces.
