Definitions

  • the invention relates to a method for separating material in a centrifugal force separator (ZKS) and a device for carrying out this method.
  • ZKS centrifugal force separator
  • ZKS enable the separation of particles based on their density relative to the density of a separation medium. Originally developed for coal processing, ZKS are now used for a wide variety of sorting tasks.
  • ZKS typically comprise cylindrical housings whose longitudinal axis is usually aligned at an angle, for example, between 20° and 40°, to the horizontal during operation.
  • Separation medium is usually introduced through an involute-shaped inlet in the housing shell in a lower region of the ZKS, creating a vortex flow with an air core along the longitudinal axis of the ZKS, and the separation medium exits through an involute-shaped outlet in the upper region of the housing shell.
  • the material to be separated is introduced through an inlet usually located centrally on an upper end face of the cylindrical housing.
  • Low-density particles float at the interface between the separation medium and the air core and are transported by gravity along the longitudinal axis of the ZKS to an outlet located centrally on the lower rear side of the cylindrical housing.
  • the particles contained in the material to be separated can thus be sorted according to their density in relation to the density of the separation medium.
  • CMSs are also known under the names dense media separators (DMS), cylindrical cyclone separators, dynamic separators, and the product names Dyna Whirlpool separators, TriFlo separators, and LAR-CODEMS (large coal dense media separators).
  • DMS dense media separators
  • Suitable CMSs are for example in the DE 198 47 229 A1 and in the WO 02/00352 A1 revealed.
