3. Simply the components of cement ► Limestone caco 3 ► Clay ► Sand ► Iron oxides or slag (iron ore) Note :Vary the ratio of the component to another

4. . ► First: Removing over burden layer ► Second Type of method : o Digging in soft material Ex :sand quarry. o Ripping in medium to hard material) Ex: Clay and may be limestone o Drilling and blasting (in hard material )

5. Method of quarrying in L.S Quarry ► 1)Ripping. ► 2) Drilling and blasting. The two methods depending on the environment. But, Ripping: need long time and give small amount of rock. Drilling and blasting: need short time and give large amount of rock.

6. Methods of Quarry depending on ► Capacity. Hardness. Cost. ► Environment. ► Quarry land nature ► Environment. ► Quarry land nature.

7. Drilling ► After removing the over burden layer from the quarry land we used drilling machine.

8. In case of drilling and blasting In case of drilling and blasting ► Vertical ► Inclined Each method had to be special But The second method used because it is more safely

9. Blasting ► After drilling process we used ► Blasting We use dynamite + ANFO + Gelatene dynamite + ANFO + Gelatene Anfo : moderate effect Anfo : moderate effect Gelatene : High effect Gelatene : High effect ► Note We used both of them during blasting but we used Anfo with high amount than Gelatene.

10. Transporting After using blasting process theAfter using blasting process the machine transported the blasted L.s to crusher machine. It is very important to be quarry near crusher machine to reduce the cost of transporting.It is very important to be quarry near crusher machine to reduce the cost of transporting. Note : we need to reach to Homogeneity

12. Cement production stages ► ► Quarry ► ► Raw mix bending ► ► Row mils ► ► Preheating (Q) منين بنحصل علي الحرارة في المرحلة دي ► ► Kiln ► ► Cooler ► ► Cement mils ► ► Packing

13. Stages of cement production ► Quarry. ► Crushing. ► Raw Mill. ► Kiln. ► Cement Mill. Note : we have get the material from the quarry so we are going throw the process of manufacture

14. Before the rock enter to crusher.the rock must be in size (65x65) Cm. rock must be in size (65x65) Cm. If the blasted L.s rock is large we used (hydrollic hammer ) for reducing its size The crusher capacity is (1500 Ton/H ). L.S Hammer crusher

15. Control of hammer crusher

16. Belts Safety of belts: ► 1)Drift switch Prevent the belt from displacement. ► 2)Rope switch Prevent persons and belts. ► 3)Speed switch To watch the dorphel movement.

17. Belts

19. Magnet

20. Clay quarry Clay is Hydrous Al Silicate. ► ► We have two quarries of clay ► ► Clay 1 (rich with Alumina –dark in color ) ► ► Clay2 (rich with Silica –lighter in color ) ► ► Clay is the source of (Al-oxides & Si-oxides inlarge amount and Fe-oxides in small amount ) Stages of clay quarry ► ► 1) Removing the over burden layer ► ► 2) Ripping (because it is softer than L.s). ► ► 3) Transporting.

21. The clay crusher machine (roller machine) ► ► The clay crusher give 500 Ton/H

22. The clay crusher control system

23. Reclemer

24. Stacker

25. Buffer soil (storage) ► ► In normal case it stored 3000 ton
