Abstract

Material of different grain sizes, e.g. limestone, dolomite or magnesite is divided into at least coarse and fine grains. The moving grid charger in which the material is preheated by exhaust gases is fed in two layers, the lower being of unheated fines, while the coarse grains are first preheated in a stack preheated and then fed onto the fines as an upper layer, so ensuring uniform preheating of the whole.
