Panorama Longitudinal Blending Beds

SCHADE 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)
