Have long been used for the continuous heat treatment of a variety of raw materials. The rotary retort furnaces is particularly adaptable to controlled atmosphere operation up to 500°c. These furnaces are particularly well suited for the processing of raw materials because the rotary conveying action tumbles the materials, breaking up any jams or tangled clumps facilitating more thorough heat treatment of each of the individual part. The traditional rotary retort concept is not without problems: improper and uneven loading, jams of parts formed at the charge end that cannot be broken up in the retort, the maintenance of rotary bearing and seals within the heated shell and the loss of controlled atmosphere.
