Panorama Longitudinal Blending Beds

Blending Beds

Consistency of the employed raw materials plays an important role in many industrial processes. This blending or stabilisation function is assumed by stockyards featuring a blending bed installation. The maximum blending effect in a front-side stockpile removal is achieved by a bridge scraper when the stacker has formed the stockpile in such a way that its cross-section ideally exhibits many layers of identical material. As with buffer storage, blending bed installations can be arranged indoors.

Open storage with bridge scraper

  • Stockpile formation using the CHEVRON method with mobile belt stacker featuring raiseable and lowerable boom
  • Stockpile removal, front-side with bridge scraper
  • optimum uniformity and final grain size of bulk material
  • Fully automatic operation
  • Simultaneous storage and reclaim (with more than one stockpile)

Covered storage with bridge scraper

  • Stockpile formation using the CHEVRON method with mobile tripper carriage, normally arranged under the shed roof
  • Stockpile removal, front-side with bridge scraper
  • optimum uniformity and final grain size of the bulk material
  • Fully automatic operation
  • Simultaneous storage and reclaim (with more than one stockpile)


Bridge Scraper

Reclaim of the stockpile from the front-side for maximum blending effect in combination with a suitable stacking process.

  • Discharge of conveyed materials onto a reclaim belt via a concrete ramp (parallel to the blending bed) or via an inclined trough
  • Drag trough as a solid component of the scraper bridge on the discharge charge end of the scraper chain
  • Effective homogenisation of the bulk material
  • Spans up to 60 metres.
  • High conveying and homogenisation capacities (with coal up to 2,200t/h)
