Drum centrifuges

Offering several advantages over the more traditional beam centrifuges, Broadbent Genesis Geotechnical drum centrifuges are developed from the innovative design patented by Emeritus Professor Andrew Schofield FREng, FRS, of Cambridge University Schofield Centre.

In addition, Broadbent Genesis has developed the modular centrifuge – the world’s first single-platform, multi-test environment incorporating an interchangeable beam and drum centrifuge. We designed this revolutionary centrifuge specifically to provide a complete test environment for civil engineering researchers. Visit our Special Projects section for more details.

2.2M Drum centrifuge
  • lower civil engineering costs
  • conduct multiple tests on a single sample
  • change tools, sensors etc whilst sample is ‘in flight’
  • model high 1G sample lengths, up to 2,500m
  • lower power consumption
  • virtual beam mode gives wider application options
  • ‘in flight’ advanced manipulation of tool position
  • more compact than beam centrifuges
  • safety shield feature
  • large sample footprint
  • current designs – up to 400 times gravity
  • free-standing
  • rotating parts housed within robust casing
  • aerodynamically efficient
  • engineering support services available worldwide
