ABSTRACT:
An improvement to a drum drying and mixing apparatus includes a baffle plate arrangement is supported externally of the drum adjacent one end thereof and is inserted longitudinally from that one end into the drum. Baffle plates of the arrangement are disposed in the veil of materials in a drying section of the apparatus. Pivoting the baffle plates about an axis substantially transverse to the direction of the falling material in the veil modifies the veil to create a channel substantially void of material through at least portions of the veil. Hot drying gases moving longitudinally through the veil encounter a reduced resistance to the flow in the channel and divert from movement through the falling materials in the veil to move through the channel within the region of the veil. As a result the heat transfer from the drying gases to the aggregate materials is reduced and the final temperature of the hot drying gases exiting from the drum increases. The arrangement may be used to control the temperature of the drying gases exiting from the drum and advancing to a baghouse filter.
