Measuring moisture of coke and iron ore/ concentrate in bunkers and silos

An online moisture measurement at the bunker or conveyer belt provides real-time information on the moisture content before the material enters the blast furnace.

Customer benefits

  • Improved thermal control the blast furnace operation
  • Online, real-time process information
  • High accuracy with very good reproducibility
  • The measurement can be installed at, or into the bunker/silo wall


  • A neutron source emits neutrons, which will be converted to "slow" neutrons, after they impact multiple hydrogen atoms. The amount of backscattered "slow" neutrons are proportional to the coke moisture
  • Non-contact measurement and no disturbance in the flow
  • Highly reliable, long-term solution
  • Maintenance-free operation
  • Easy to install or retrofit on existing bunkers or silos
  • Large measuring volume provides representative measurement
