Carbon Sulphur analyser CO2/SO3



ON LINE ANALYSIS ON
CEMENT TO QUANTIFY LIMESTONE AND GYPSUM ADDITIVES
CLINKER TO CONTROL ITS SULPHUR RATE
HOT MEAL TO CONTROL ITS CALCINATION DEGREE


High frequency measurement to optimise the relevant stage in the process

Advantages :
 
  • Automatic on-line equipment with integrated sample preparation, measurement and residues evacuation
  • Up to 3 sampling points can be controlled by the same analyser
  • Output information used to control cement mills additives and thus stabilize cement composition
  • Possibility to use this equipment to regulate the SO3 rate in clinker or the calcination degree of the hot meal at the optimum level
  • Easy to install either on site or in automated laboratory


Principles :
 
  • Custom designed sampling and transport systems
  • Precise sample weighing with an electronic scale
  • Cement / iron / tungsten mixing in a ceramic crucible
  • Calcination at 1350 °C under O2 flow in an induction furnace
  • Infra red calcination gas analysis
  • Ranalog 4-20 mA outputs (Profibus communication also available) of limestone & gypsum rates to the grinding mill control unit
  • Automatic discharge of used crucibles


Performances :
 
  • High frequency analysis : up to 4 analyses / hour
  • Measurement range and accuracy :
            C channel :    0 to 20 %    ± 0,125 %
            S channel :    0 to 5 %    ± 0,05 %
  • No sample cross contamination
  • Automated crucibles (± 200) magazine
  • Automated dedusting system for sample residues
  • 3 operating modes: Automatic – Calibration - Manual
  • O2 consumption: 3 litres / min (during analysis)


Specifications :
 
  • Height : 1800 mm
  • Depth : 910 mm
  • Length : 2000 mm
  • Weight : 500 kg
  • Power supply : any from 380 to 600 V; 50-60 Hz
  • Compressed air supply : 6 bars, dry and clean
  • Location : next to cement mill(s), cooler(s), precalciner(s) or in the laboratory
