ABSTRACT:
A rotary calciner for the treatment such as thermal treatment of particulate solids equipped with riffle flights, each in the form of an inverted V shape. The flights are arranged in at least two rows on the inner circumferential wall of the calciner, the rows being staggered so that the apex of each riffle flight is directly beneath the space between two riffle flights in the row above. The riffle flights provide continuous mixing and improve gas-solid contact curing rotation.
