The kiln is at the heart of the manufacturing process. Once inside the kiln, the raw meal is heated to around 1,500C it is of a similar temperature to molten lava. At this temperature, chemical reactions take place to form cement clinker, containing hydraulic calcium silicates.diergetos303.jpg" /> Summary of production process. The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder.

Cement Industrial Efficiency Technology Measures

Dry, semi-dry, semi-wet and wet processes are the four main process routes that are used for the production of cement. Dry processes are considerably more energy efficient but the choice of technology mainly depends on the state of raw materials.diergetos203.jpg" />

Differences between Wet Cast and Dry Cast Concrete

Dry Cast. More rigid formwork is necessary for dry-cast manufacturing than for normal-slump concrete production. Rigid forms and accessories will transfer vibrations more effectively and can withstand the continuous impacts of the consolidation process. Otherwise, the forms will likely wear or become damaged prematurely.diergetos75.jpg" />

Cement Kilns Dry and semi-dry process kilns. After the 1920s, the British industry (like that of the USA) entered into another period of technological complacency, due in part to the very low cost of fuel. The development of more energy-efficient Dry Processes was therefore left to Germany and Japan, where fuel was more expensive.diergetos95.jpg" />

Dry cast on the other hand has a low water to cement ratio and a zero slump. This "Dry Process" allows you to use one form and pour numerous pieces without deformation. The concrete is stripped and resembles Hard clay and dries within and hour. The Del Zotto Concrete Mixer is proven itself and a larger market for dry cast products is in demand.diergetos305.jpg" />

The wet process, which feeds raw material to the kiln as a slurry, averages 6.4 GJ/metric ton (5.5 MBtu/ton) of cement compared to dry process with preheater and precalciner which averages 4.2 GJ/metric ton (3.6 MBtu/ton) of cement. The weighted average for all four processes is 4.8 GJ/metric ton (4.1 MBtu/ton) of cement.diergetos306.jpg" />

Dry Process for Manufacturing of Cement Gharpedia. In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill.
