1. CECIL CONCRETE FACTORY
PORTUGAL
2007

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

3. 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

4. Raw Material Crushing
Hammer Crasher

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

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

7. 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

8. 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

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

10. 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
