Attrition Units

Jet Attrition Unit

  • Small sample sizes (20-150g)
  • High temperature (Ambient – 900°C)
  • Gas conditions (Oxidizing, Reducing-H2/CO/CO2/CH4, Inert)
  • Batch solids addition (During Test)
  • Material experiences jet destruction via induced grid jet via bubbling bed
  • Ease of varying operating parameters
  • Methods of Analysis: Particle Size changes, in-situ material reactivity, measurement of elutriated particles.
  • Service provided: screening service for materials (i.e. limestone screening for sulfur capture, oxygen carrier screening….)

Cyclonic Attrition Unit

  • Small sample sizes (20-150g)
  • Varied cyclone velocities
  • High temperature (Ambient – 900C)
  • Varied Gas conditions (Oxidizing, Reducing-H2/CO/CO2/CH4/SO2/H2S, Inert)
  • Batch solids addition (During Test) Solids addition can be combustion materials or additive materials
  • Material experiences cyclonic and impaction via internal draft tube (acting as a cyclone/wall impaction mechanism)
  • Methods of Analysis: Particle Size changes, in-situ material reactivity, measurement of elutriated particles.
    Service Capabilities: Material evaluation and screening, previously used for limestone screening for reactivity and attrition propensity. Similar evaluation and screening for potential oxygen carrier materials. This test equipment also lends itself to additional screening of the mechanical, thermal, and chemical reaction stresses applied to particles during varied process conditions.
