Abstract
A pellet cooler (10) includes an endless traveling grate conveyor (30), drive apparatus (34,36,40) operatively associated with the conveyor (30) for moving the conveyor in continuous travel about a continuous path, and a plurality of non-perforated material support trays (32) mounted to the conveyor in juxtaposed overlapping relationship to form a substantially continuous surface about the continuous path defined by the conveyor. Each of the material support trays comprises an elongated, laterally extending bi-lobed plate (50) having a first laterally extending outwardly projecting arcuate larger radius lobe (60) along one lateral extend thereof, a second laterally extending outwardly projecting arcuate smaller radius lobe (70) along the other lateral extent thereof, and a substantially flat laterally extending mid-portion (56) interconnecting the first lobe and the second lobe. The juxtaposed material support trays (32) are mounted to the conveyor with the first lobe (60) of one tray extending in overlapping spaced relationship concentrically over the second lobe (70) of the other of the juxtaposed material support trays thereby defining an air flow gap (80) therebetween.
