Definitions

  • the invention relates to a grinding device with a horizontal cylindrical housing, in which a rotor, which is driven by an electric motor and is designed as a disk, is arranged coaxially with fingers arranged uniformly on the circumference on both sides, the housing being closed on one side by a front cover, the outside carries a coaxially attached receptacle and is provided on the housing side with counter fingers uniformly distributed on the circumference, the housing on the drive side is closed by a rear cover and an outlet opening is formed between the disk and the rear cover.
  • the grinding device is used to grind sticky, air-stuck materials of organic and inorganic origin.
  • Such a grinding device in which a flap regulating the air flow is supplied to the receiving nozzle is classified, is known from SU-A 902 807.
  • a disadvantage of the known grinding device is the poor grinding because of the limited grinding area. This requires additional separation with complicated devices and repeated grinding of the large grain material.
  • the object of the invention is to create a grinding device with which the grinding process can be intensified without the need for additional separation.
  • the rotor is surrounded by a housing-fixed socket in which longitudinal channels are formed on the rotor side, that closed cooling channels are formed on the outside of the housing, and in that the housing side in the rear cover and in a disk attached to the rear cover a common concentric circumferential channel with a rectangular cross-section is provided, which has six radial channels evenly distributed around the circumference for supplying a fluid in the rear cover to the outside and to the interior of the housing through six outgoing radial channels evenly distributed around the circumference the disc is connected for the continuation of the fluid.
  • the grinding device according to the invention has the advantage that it can intensify the interlocking process so that an additional separation can be omitted.
  • the grinding device consists of a horizontal cylindrical housing 1, in which a rotor 2 is arranged coaxially, which is driven by an electric motor 3.
  • the axis 4 of the rotor 2 is mounted in a bearing body 5.
  • the rotor 2 is designed as a disk, on which inner fingers 6 and / or outer fingers 7, which are evenly distributed on the circumference, are formed.
  • On one end face the housing 1 is closed by a front cover 8, on the housing side of which there are evenly distributed counter fingers 9 which are arranged under the outer fingers 7 and at a distance from them.
  • a receptacle 10 with a regulating flap 11 is arranged in the region of the axis of the front cover 8.
  • the end face of the housing 1 facing the bearing body 5 is closed by a concentric rear cover 12.
  • An outlet opening 13 is formed in the housing 1 between the disk and the rear cover 12.
  • the rotor 2 is enclosed by a bush 14 which is fixed with respect to the housing 1 and in which longitudinal channels 15 with a different geometric shape are formed on the rotor side.
  • It is connected to the exterior by six evenly arranged, fluid-supplying radial channels 19, which are worked out in the rear cover 12, and to the interior of the housing 1 by six fluid-conducting radial channels 20, which are embodied in the disk 17.
  • the geometric shape of the fingers 6 and 7 and the counter fingers 9 of the front cover 8 is selected depending on the requirements when grinding different materials.
