ROTARY HEAT-TREATMENT APPARATUS

摘要

Rotary heat-treatment apparatus comprises a casing (11) formed as upper and lower shells (12, 13) and defining a cylindrical heating chamber. Material to be treated is conveyed through the heating chamber within a plurality of tubes (26) which are carried on a rotatable shaft (21) arranged on the longitudinal axis of the casing. At its opposite ends the casing is effectively closed by mounting plates (24, 25) by means of which opposite ends of the tubes (26) are supported, the mounting plates themselves being supported by the shaft (21) for rotation therewith. The chamber may be heated by means of combustion products from internal or external fluid-fired burners or by means of internal fluid-fired or electric radiant heaters.
