  • Patent number: 9278357
    Abstract: An agitator ball mill for the fine-grinding or dispersion of a grinding material, including a container the inner wall of which delimits a cylindrical or conical, vertically arranged grinding chamber, a grinding material inlet for feeding the grinding material into the grinding chamber, a grinding body inlet for introducing grinding bodies into the grinding chamber, and a grinding material outlet for discharging the ground or dispersed grinding material from the grinding chamber, and a rotatably driven agitator having at least one agitator element and extending in the axial direction in the grinding chamber.
    Type: Grant
    Filed: September 9, 2013
    Date of Patent: March 8, 2016
    Assignee: Willy A. Bachofen AG
    Inventors: Pascal Hug, Frank Ronald Lang, Berndt Joost
  • Patent number: 8814071
    Abstract: An agitator ball mill having a milling chamber and an agitator having a rotatably mounted and driven agitator shaft and accelerators arranged thereupon, wherein the accelerator that is arranged furthest downstream, that is, the accelerator closest to the milling material outlet, lengthens axially and extends along the axial length of the sieve.

  • Patent number: 8118247
    Abstract: An agitator ball mill for finely grinding or dispersing material has a cylindrical or conical grinding chamber for accommodating grinding bodies and for accommodating the material which is to be ground or dispersed. It also has an inlet, which is arranged at one end of the grinding chamber, an agitator, which extends in the axial direction into the grinding chamber and has agitating means, and a product outlet for the ground or dispersed material, the product outlet being arranged at the other end of the grinding chamber. Arranged in a central region at the outlet end of the grinding chamber is a gas outlet through which gaseous components, but not grinding bodies, can be discharged out of the grinding chamber.

  • Publication number: 20110121115
    Abstract: An agitator ball mill for finely grinding or dispersing a material comprises a grinding chamber for accommodating grinding bodies and for accommodating the grinding material. The grinding chamber has an inlet for the grinding material and is provided with an agitator which can be driven in rotation and has agitating means for moving the grinding bodies and the grinding material. A separating arrangement for separating off the grinding bodies from the ground material is arranged in the grinding chamber. The grinding chamber also has a product outlet for the material which has been ground and freed from grinding bodies, wherein the ground material passes through the separating arrangement into the product outlet. The separating arrangement is designed as a sedimentation centrifuge which can be driven in rotation and has an axial entrance, or an entrance which is at least in the vicinity of the axis, for the material intermixed with the grinding bodies.
