Calcination Service

Toll Calcination services are provided out of our site in Sheffield. We operate two indirect fired rotary calciners, capable of operating up to 650°C. 

Our calciners are indirect fired making them particularly suited to powders, and finely divided materials. In these cases a directly heated calciner would not be ideal, due to the nature in which the heat is transferred to the media.

Indirect firing also means that the product does not come into contact with the products of combustion, eliminating the risk of contamination and maintaining product purity. 

Our Calciners can be used for product treatement as well as precious metal recovery
