Fine Coal Centrifuge

Client Name Withheld

The client’s Coal Preparation Plant previously incorporated a dewatering screen in its fine coal circuit. The limited capacity of the screen allowed for some of the flotation tails to bypass the circuits reflux classifier and report untreated to the tailings thickener, resulting in a loss of product yield. In order to increase tailings recovery, the client elected to replace the dewatering screen with a fine coal centrifuge.

Wave was engaged to provide mechanical, structural, piping and electrical design services as well as electrical construction and commissioning management for the fine coal centrifuge installation.  The design incorporated the following:

  • Product and effluent chutes
  • Piping and pipe supports
  • Structural supports
  • Electrical drive cells, local control stations and field junction box


The installation was tied in over a 36 hour shutdown and the client has reported an increase in yield due to the fine coal centrifuge. As a result of the successful completion of this project, Wave has been invited by the Project Manager to provide more services to the site.
