Asingle pass rotary dryerin which heated gas and a moist material is blown through a rotatingdrum. Thedrumhas inwardly extending flights or vanes which deflect particles of the material back into the gas flow. A flight is oriented at an obliqueangleto the longitudinal axis of thedrumin order to present an ascending ramp to incoming material.
