The production process of cement 6 stages: Quarry Extraction Raw Material Crushing Raw Material Storages Clinkerisation Cement Grinding Packing

Quarry Extraction Cleaning the area Drilling with special equipment Introduction of the explosives Detonation Loading and Transport Crushing Aim: to prepare good conditions for the cement production

Raw Material Crushing Hammer Crasher

Raw Material Storage Marl Storage, Circular Store Capacity: 80 000 t Sand Storage Hangar Capacity: 3500 t Iron Oxide Storage Capacity: 1500 t

Raw Material Grinding Vertical mile Dynamic Separator on top of the mile Mixing, drying

Clinkerisation Kiln System: Preheater Tower 4 stage cyclones first chemical reactions occur Rotary Kiln End of chemical reactions Coal, Oil, Alternative Fuels Inclination of 3,5% Clinker Coolers: cooling with air and water Coal and Pet Coke Grinding Vertical mile, Dynamic Separator, Size reduction, Drying Control: Fineness, % Moister Waste Valorization or Co Incineration Alternative Fuels: Fluff, Animal Chips, Wood Chips, Paper, Textiles, Plastic. Reduction of the green house effects

Cement Grinding Gypsum, Clinker Tubular mile with two chambers Grinding Balls in a special steal The quality of the cement depends on the limestone: CEMENT I, II, III, IV Products are certified by standards The quality and process control takes samples from: raw material, raw mile, clinker, fluel, cement Cement= Clinker + Gypsum + Limestone

Packing With tucks and boats Control of atmospherical emissions: electrostatic precipitator , control room, control of the air quality

Quarry rehabilitation 6 million euros were invested local species are protected during the exploration as well Difficulties: the local plants are growing slow Plant Nursery: green fix
