Abstract
A preheating moist fine material, such as pit coal and lignate, peat, wood, oil shale, or even ores or limestone for cement production, and an apparatus for carrying out the method are disclosed. Moist fine material is mixed above a heater with predried and preheated material until the mixture is made fluid. The fluid mixture slides down between and piles up to a level above the heater. A part of the predried and preheated fine material is removed from below the heater in an amount corresponding to another part thereof and is conveyed to above the heater with the moist fine material.
