The drying drum is the heart of a rotary dryer, and the place where the drying gas and wet material are brought into contact. The material is showered through the air by rotating the drum. As the drum rotates, lifters mounted on the shell wall carry material up to the top, where it drops as a continuous curtain as the air passes through it.

Astec Re-designs Aggregate Dryer for Energy Savings

The drying process, though very energy-intensive, ensures that the asphalt will bind to the rock. Inside the drum the aggregate is kept in motion by shaped scoops called flights attached to the inner surface, which produce a "veil" of falling material. Better veiling action improves heat transfer and speeds drying, reducing fuel consumption.
