Abstract

An apparatus and method for drying or preheating granular or pulverulent material. The apparatus is in the form of an upright stack or tubular conduit within which a continuous helical surface extends sloping in a downward manner. Heated gas flows from the bottom of the stack along at least one vertical channel within the stack to heat the material descending down the stack. Specific means are provided within the stack to prevent the gas from flowing continuously over the helical surface.
