At the core of the sintering process, the kiln shell is a long cylinder made of steel, with a typical length ranging between 60-100m and weighing around 1000t. Despite this impressive mass, the kiln shell is a giant with feet of clay, exposed to harsh environmental conditions. The inner part of the kiln is heated on one side by a flame to 2000˚C
