The New Krebs Coal Spiral is a technologically advanced design:

  • Krebs rougher/cleaner “CPX” spiral design allows coal to be rewashed
    in a second stage spiral helix located immediately below the
    primary spiral.
  • Spiral concentrators use differences in density to separate fine coal
    simply, efficiently, and cost effectively
  • Krebs offers a comprehensive range of spiral units for coal
    preparation

Krebs Coal Spirals are supplied in complete modular designs including support framework, feed distribution system and product piping system. Assemblies will be designed to meet your application requirements. Consult a FLSmidth Krebs Sales Engineer for any technical or quotation requests.

New Collection Boot Design

How new collection boot design handles allow for positioning of all cutters simultaneously.  There is no need to reach into Helix to adjust.  The mechanism allows positive lockout once selection is made.

Spiral Boot

 
Revised internal profile assures no misplacements into other product streams. The internal rotation breaker reduces wear on boot assembly.
