Definitions

  • Pin mills of this type have an annular stator which is provided with cylindrical pins arranged parallel to one another.
  • a rotor in the form of a disk is arranged inside the stator, on the outer circumference of which a number of cylindrical pins arranged parallel to the stator pins are attached, which pass the stator pins leaving a small gap free.
  • the rotor disc is driven at high speed by a motor located outside the mixer tank.
  • the rotor and stator are spaced from the inside of the wall of the container.
  • the mixing tools of the mixer can be designed and arranged such that they slide at least partially through the space between the rotor and stator on the one hand and the container wall on the other hand, so that the largest possible part of the container is axially swept by the mixing tools. This measure therefore serves to prevent dead zones.
