Roller grate apparatus for simultaneously transporting and transferring heat to or from a bed of material particles has elongated cylindrical parallel horizontal rollers rotatably driven in the same direction; filler bars disposed in the nip between adjacent rollers and together with the rollers forming a generally flat surface with constantly moving portions which continually tumble the material particles and urge them thereacross in a direction transverse to the roller axes; gas passage apertures in the rollers which permit a heat transfer gas stream to pass through the rollers; a heat transfer chamber spanning the rollers; and a fan for blowing a heat transfer gas stream through the chamber and the material bed being transported by the rollers.
