How Calcination Works
Calcinatination (also commonly referred to as calcining) is the decomposition of a material by heat.
Processes Induced through Calcination
Calcination often uses heat, sometimes in the absence of oxygen, to induce one or more of the following things:
- Phase Transition/Change
- Removal of a Volatile Fraction
- Removal of Crystalline Water
- Chemical Separation (Dissociation)
Rotary kilns are extremely flexible thermal processing devices, and are capable of processing a wide variety of materials. Some of the materials commonly calcined in a rotary kiln include:
- Ceramics and Refractories
- Calcium Carbonate
Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type.
It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it can move on to transportation or storage.
