90% Recovery Rate of Active Clay

The BRS-1 will help a foundry elevate your casting quality based on improved green sand properties. Shorter mulling times result in an overall operational efficiency, lower emissions and reduced environmental footprint.


  • Over 90% recovery rate of active clay, process up to 1 ton of dust / hour
  • Reduce bond additions by up to 40%
  • Reintroduction of fully hydrated, activated clay provides efficient green sand property development
  • Reduced mull times allows for increased mold production
  • Shortened mulling times result in lower energy costs and reducing wear and tear on mulling equipment
  • Reduced variability of green sand properties
  • Environmental sustainability
  • Fully automated system
  • Easily integrated and compact machine design
  • Chemical free
  • Recycling of green sand baghouse dust drastically reduces dependency on landfills and reduces disposal costs
  • Reduces labor and costs tied to handling and bagging materials for disposal
  • Lower foundry emissions
