  • Publication number: 20220113226
    Abstract: A laboratory mill is shown and described with at least one oscillatably mounted grinding bowl holder for at least one grinding bowl and with at least one line for transporting a liquid or gaseous medium, the line having at least one compensating element for compensating relative movements between the grinding bowl holder and/or the grinding bowl and a stationary part of the laboratory mill. In accordance with the invention, a rigid compensating element is provided for compensating relative movements, wherein the compensating element is elastically deformed at least in regions during an oscillating movement of the grinding bowl holder and wherein the compensation of relative movements is effected free of parts of the compensating element connected to one another so as to be movable, in particular rotatable and/or pivotable, relative to one another and only by elastic deformation of the compensating element.

  • Patent number: 10058871
    Abstract: A ball mill is provided comprising at least two milling cup retainers arranged on a machine base plate, each milling cup retainer being designed for a milling cup clamped in the milling cup retainer in a lying position, each milling cup having end-face milling cup ends and a filling of balls as milling bodies and comprising a drive that causes an out-of-phase rotational motion between the milling cup retainers.

  • Publication number: 20150129692
    Abstract: Ball mill (10) comprising at least two milling cup retainers (13) arranged on a machine base plate (12), each milling cup retainer being designed for a milling cup (23) clamped in the milling cup retainer in a lying position, each milling cup having end-face milling cup ends and a filling of balls as milling bodies and comprising a drive that causes a rotational motion of the milling cup retainers (13) characterized in that each of the milling cup retainers (13) arranged in pairs is put in restraint-guided circular motion, oriented parallel to the plane of the machine base plate (12) by means of the drive via two eccentric shafts (25) connected to the milling cup retainers (13) on faces opposite to each other in relation to an axis of symmetry of the milling cup (23), a counterweight (28) being arranged on each of the two eccentric shafts (25) associated with a respective milling cup retainer (13) and passing through the machine base plate (12), below the machine base plate, and on the face of the eccentric s

  • Patent number: 8042754
    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.
