Buffer Storage
Stockpiles are the simplest form of bulk material storage. They serve as storage or intermediate storage and are a key link between material preparation and production. Where protection from the elements is necessary or environmental regulation aspects demand it, stockpiles are also formed under cover. For both variants a series of typical stockyard configurations have emerged:
Open Storage with Portal Scraper
- Stockpile formation using mobile belt stackers with raisable and lowerable boom (slewable is also optionally available)
- Stockpile formation with portal scraper (with stockpiles of more than 30m width)
- Removal over the entire stockpile length or preselected sections
- Fully automatic operation
- Simultaneous storage and reclaim (with more than one stockpile)
- Rapid change of stockpile sections
Open Storage with Combi-Portal Scraper
- Applications where storage and reclaim do not need to be performed simultaneously
- Storage and reclaim with only one machine (lower investment costs)
- Less space requirement
Covered Storage with Portal Scraper
- Stockpile formation with mobile travelling tripper arranged under the shed roof
- Free stockpile cone or formable/removable stockpiles separated by partition walls
- Stockpile formation with portal scraper
- Reclaim possible over the entire stockpile length or in individual sections
- Fully automation operation
- Rapid changeover possible between chamber or stockpile sections
- Matched shed height through construction with two booms on the portal scraper
