Abstract
An air cooled rotary kiln collar for use in improving the delivery of preheated charge material from the rotary kiln to the second stage of a multi-stage heating process. Adustable rate fans circulate air through an annular collar at the discharge end of the rotary kiln to remove heat from the charge material and prevent it from agglomerating and sticking to the kiln.
