Carbon Regeneration Kiln
In gold adsorption, the activity of your carbon is paramount.  It is your most important factor contributing to quality adsorption, efficient desorption and low CIL/CIP tails losses.Â
Â
With carbon regeneration, the process comes first and foremost. There should be no doubt that in regenerating of carbon incorrect kiln design is almost the norm rather than the exception. Â
Â
Designed to ensure correct residence time at hold temperature of 20 minutes –not 10 minutes, Cadia Systems KX series of kilns provide stable, progressive feed of your carbon with reliable three-zone heating with independent controls, robust thermal lifter designs, co-current movement of reaction products and correct thermal conduction area and bed thickness defining retort size. Â
Â
You can be assured of 90%+ regeneration activity for fresh carbon.Â
Features
Active thermodynamic controlÂ
The importance of zone temperature control & stability to the regeneration process lead us to design probably the most advanced control system ever fitted a reactivation kiln with a computer controlled active thermal balancing control system. This system maintains optimal activation environments at each of the three zones.Â
Safety and asset protectionÂ
With KX series kilns both personal and asset protection are uncompromised. Each of the three heating zones is safeguarded by an independent overtemperature shutdown controller. Â
The retort tube is protected in the event of an electrical & flame out condition with an independent battery powered drive backup system that kicks in and monitors kiln tube rotation as it cools reducing damage to the retort in the event of a power or phase loss. New technology brings single phase AC backup drives into play, improving system reliability and avoiding costly 24 VDC battery backup system faults and failures.
