Unavoidably, during the aqueous reprocessing of spent fuel, high level liquid waste is produced, which is typically vitrified. A rotary calciner is an essential component of a two-step cold crucible melter equipment system. Owing to the calciner's long-term operation under high temperature condition, potential effects from metal creep are essential design …
For successful calciner performance, the residence time of the particles in the calciner must be longer than the time required for heating and calcination of the particles. This problem can be separated into axial and radial processes. In the axial direction, residence time and dispersion will be important, requiring experiments in full calciners.
Rotary calciners (also called rotary kilns) are fundamental in several industries. They are crucial for high-temperature material processing in enclosed spaces. Rotary calciners …
Procedyne designs and builds continuous fluid bed processors for drying, calcining, activations and other chemical processes.

Careful control over the calcination process is essential to yielding the desired end product qualities. This starts with the calciner itself. The Catalyst Calciner. While direct-fired kilns are available, catalyst calcination is always carried out in an indirect-fired rotary kiln, also known as a calciner.
Rotary hearth calciners result in less fines loss from the coke bed, resulting in a higher recovery of calcined coke per ton of GPC. This is an economic advantage when operating the calciner but leads to a product with a higher fines content (<0.5 mm), which is not always desirable for an anode paste plant. ...
Rotary Options Optimize the performance or service life of a rotary calciner with: Various rotary seal designs for operation under positive or negative pressure Material feeding systems or equipment Internal bed temperature measurement systems Auxiliary/emergency drive systems Recuperative or regenerative burner systems
The cement industry can reduce its CO2 emissions by electrifying the calciner. It can avoid emissions from fuel combustion and produce pure CO2 from the calcination reaction (CaCO3 → CaO + CO2) for direct capture.
