ColObserver® On-line sugar colour analyser
- Process Control in the Mineral industry -


  • Monitor the colour of any size of stones in real time at both the quarry and/or the plant
  • Extend the quarry lifetime
  • Guarantee constant and stable feeding at the plant inlet
  • Allow fine tuning the process parameters to hit brightness and yellowness targeted values
  • Display the colour standards and their trends
  • Detect and sort the off-spec to automatically avoid any contamination
  • Sort the stones on different stock piles according to their colour range
  • Trigger alarms and record video sequences on events
  • Record all data for full traceability

Using the latest image processing techniques, the ColObserver® performs an accurate acquisition and highly sophisticated image treatment to measure the colour of products in real time. Installed above a conveyor, the on-line colorimeter equally controls the colour of big stones at the quarry and smaller ones—down to powders, at the plant. The camera not only measures the colour in real time but also detects, sorts and counts non conformities. The stones can be sorted in various stock piles according to their colour for future blending. Alarms can be set up to divert the off-spec products i.e clay or any coloured stone, avoiding any contamination. At the plant, the ColObserver® manages the blending of various sources to stabilize the inlet feeding. In control room, the system displays the calculated data, the colour trends as well as the video of the on-going production. It records video sequences on events for full traceability and further analysis of the process.

Maintenance can be performed remotely by ITECA engineers using the available customer Internet access, with secure screen sharing software.
