At the Sv Juraj site (Figure 2), the raw material is ground in the 235t/hr capacity raw mill, before being transported to the homogenisation silo (Figure 3). The materials are calcined in the 3100t/day Polysius Dopol kiln (Figure 4) and the resulting clinker is conveyed to one of the 120t/day cement mills for grinding (Figure 5).
Thermal energy savings using Expert Optimizer (EO) Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials
