Drum centrifuges

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

In addition, Broadbent G-Max 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
