  • Conveying device for powdered and/or granulated material and mixtures of this material with liquids
    Patent number: 9051135
    Abstract: A conveying device for a mixture of free-flowing finely divided solid materials, in particular for powdered and/or granular (mixed) material, especially polymer granules with a liquid includes a telescopic pipe which is vertically arranged and can be flexibly fitted for conveying a mixture of preferably polymer granules with a liquid, for example for flushing a contaminated conveying device.
    Type: Grant
    Filed: March 26, 2012
    Date of Patent: June 9, 2015
    Assignee: Bayer MaterialScience AG
    Inventors: Herbert Ungerechts, Hans-Jörg Frank, Markus Hagedorn
  • Conveying device for powdery and/or granulated material
    Patent number: 9038676
    Abstract: A conveying device for free-flowing fine-particle solids, in particular for powdery and/or granular (mixed) material, especially plastic granulate, includes a vertically arranged and flexibly mountable telescopic pipe for the conveyance of, preferably, polymer granulates, for example in a plant for the filling of polymer granulates.
    Type: Grant

    Date of Patent: May 26, 2015
    Assignee: Bayer MaterialScience AG
    Inventors: Herbert Ungerechts, Hans-Joerg Frank, Dieter Scholten, Markus Hagedorn
  • Mixing silo
    Patent number: 9028132
    Abstract: A mixing silo for free-flowing finely divided solid materials, in particular for powdered, fibrous and/or granular mixed material, especially polymer granules, specifically suited for mixing polymer granules, having an excellent mixing quality and at the same time a simplified and improved suitability for washing out in order to avoid cross contamination. The mixing silo may be used for homogenizing possibly inhomogeneous polymer granule batches in the form of a stream of product from a process producing polymer granules.

  • Mobile classifier
    Patent number: 8783465
    Abstract: A mobile classifier (deduster) has docking devices, flushing devices and control for the dedusting of granules, in particular polymer granules, with preference polycarbonate granules. The mobile classifier can be set up at different locations underneath silos. To perform its function, the mobile classifier is technically connected to stationary pipelines, filters and fans.
