Free lime analyser KLC3



THIS ANALYSER MEASURES THE FREE LIME RATE IN CLINKER

Key information required in the cement manufacturing process to guarantee the end product quality without excessive burning



Advantages :

  • Automatic on-line equipment requiring no human intervention
  • Up to 3 sampling points can be controlled by the same analyser
  • Monitoring and control of kiln operations
  • High cost savings by the automatic adjustment of burning conditions temperature to the target free lime rate
  • Improved quality by continuous control of the clinker specifications
  • High reliability level due to the precise measurement with a failure management software program


Principle :

  • Custom designed automatic sampling & transport systems
  • Clinker grinding
  • Sample & glycol precise weighing
  • Mixing & heating of the solution
  • The following chemical reaction occurs between the free lime in clinker and the ethylene glycol: CaO + (CH20H)2 -> H20 + (CH20)2²- + Ca2+
  • Conductivity of the solution is measured
  • Output information transmitted to the kiln management unit
  • Waste ejection


Performances :

  • High frequency analysis : up to 5 analyses / hour
  • High performance grinding unit that guarantees a constant fineness
  • No sample cross contamination
  • High precision of sample weighing combined with automatic weight variation compensation system (patented)
  • Conductivity measurement carried out at a high and constant T° (80°C)
  • 4 operating modes: Automatic - Calibration - Manual - Test
  • Precise results : standard deviation on the analysis of 0,05


Specifications :

  • Height : 1853 mm
  • Depth : 833 mm
  • Length : 1833 mm
  • Weight : 500 kg
  • Power supply : any from 380 to 600 V ; 50-60 Hz
  • Compressed air supply : 6 bars, dry and clean
  • Location : - close to the cooler(s)
                    - in the laboratory


Option : Independent inductive toroidale probe

This patented option allows, in view of a total quality control, the confirmation of the free lime measurement obtained by the analyzer’s conductivity probe by an independent inductive toroidale probe implemented at the level of waste ejection.

This solution of redundant analysis allows the detection of the following failures:


  • Problem during the mixing of clinker & glycol
  • Problem of temperature regulation or measurement
  • Conductivity probe damaged, not properly adjusted or disconnected
  • Drift of the conductivity card
