The milling distance obtained by the good transport of the raw materials is fed from the preheater in the rotary kiln to about 1450 ° C. Modern steel processing furnaces are the largest motor furnaces with diameters of 4-8 meters and lengths of up to 80 meters. The rotational kilns are shortened again and the rotational speeds have increased.
