LAFARGE Cement Cizkovice Project Specification InvestorLAFARGE Cement, a.s. LocationCizkovice plant, Czech Republic Project goals -Storage hall for secondary alternative fuels inside the plant -Dosing technology located inside the hall for dosing of materials to the pipe conveyor -Pipe conveyor for transport of materials from the hall to the existing preheater tower © BEUMER Group /7

Basic engineering Detail engineering (incl. project documentation for building permit) Delivery of equipment Hall building-up supervision Erection and start-up Additional service -Customer service -Spare parts -Modernization and re-equipment © BEUMER Group /8 OUR COMPETENCE = COMPLEX ASSURANCE OF THE PROJECT Project Description

Main project parameters Purpose Manipulation and environmental storage of separate materials Conveying of materials incl. their mixtures to preheater Materials Secondary alternative fuels – medium-cohesive material containing slightly sticky ingredients (sludges, crushed tyres, industrial pellets) Capacity Storage hall – approx m 3 Conveying – up to 25 t/h Operation Fully automatic Safe Ecological Investment (budget) Approx. 2.6 million EUR © BEUMER Group /9
