Abstract

A method can be used to cool bulk material in a fine material cooler. The method may involve admitting bulk material to be cooled into the fine material cooler through a material inlet, conveying the coarse material with a first mechanical or pneumatic conveying unit, and conveying the fine material with a second conveying unit in a conveying direction through the fine material cooler to a material outlet. The bulk material may have a fine material proportion of 70% to 95% and a coarse material proportion of 5% to 30%. The fine material may have a grain size of 10-5 mm to 4 mm, and the coarse material may have a grain size of 4 mm to 100 mm.
