Rotary Calciner by Therelek

Multi-zone control electrically heated rotary calciners of varying lengths depending upon output and function are selected for even, uniform and controlled heating across the length of the rotating drum / rotating tube.

For proper mixing of material and uniform heating to take place within the rotary member material lifting flights are designed based on the stickiness or dryness of the feed.
 
Various sealing arrangements are possible to ensure the atmosphere within and fumes, hot air and off gases are taken out in an environmentally friendly manner.
 

Generally post-cooling there is a scrubber arrangement to scrub the waste gases emanated. Applications of these rotary kilns and rotary calciners vary from carbon regeneration rotary kilns, powder, ore concentrate and mineral rotary dryers, to rotary calciners for alumina and various ceramics, granulates and agglomerates.

Why Choose Therelek?

  • Therelek Engineers designs and manufactures rotary calciners to the requirement of the end-user.
  • Rotary calciners are directly or indirectly heated by gas-fired burners, the rotating element is a metallic tube.
  • The orientation of the burner (or burners) depends on the application and functional requirement and can either be located at the entrance of the calciner or perpendicular to the calciner rotation.
  • The rotating metallic tube and rotation speeds are determined by the composition of the feed and output required, and the material selection is based once again on the composition and operating parameters like temperature and gases formed during the process.
  • Suitable cooling arrangements are made to ensure the feed comes out of the rotary calciner at the acceptable temperature range without risk of oxidation.
