A mounting structure for use in rotationally supporting a rotatable drum dryer is provided which prevents spauling, flaking and pitting of the dryer tracks, which supports the rotational movement of the dryer, and which prevents axial shifting of the dryer. The mounting structure preferably includes a fixed base, at least a pair of proximal, continuous, annular tracks fixedly secured to the dryer, and a corresponding pair of trunnion rollers rotatably coupled with the base and adapted for contacting the faces of the tracks respectively. The mounting structure also advantageously includes at least one thrust wheel for engaging the side of one of the tracks to prevent axial shifting of the dryer. More particularly, two mounting structures are provided, one for each end of the dryer, and each mounting structure includes two pairs of thrust wheels, one pair engaging the side of each track and opposedly configured to prevent axial shifting of the dryer in either direction.
