The cement clinker is ground as finished cement, in a vertical roller mill for cement or in ball mills similar to those normally used for grinding hard raw materials in dry and semi-dry processes. However, the cement clinker is more difficult to grind than raw materials and must also be finer ground. Therefore, finishing grinding ball mills are ...

Clinker, and clinker substitutes, are the active components that confer cement its binding properties. Producing traditional cement clinker is an extremely energy and CO2 intensive process. In the EU, 90% of clinker is now made via the more energy efficient dry clinker-making process (2). Older, less efficient wet kilns have almost been …

In a rotary kiln system producing cement clinker, gas flows are counter-current to material flows. Gases enter the kiln as secondary air at about 600°C – 1100°C and rise abruptly to over 1750°C as heat from fuel combustion, and the exothermic heat of clinker formation are released. The gases transfer heat to the material in the kiln as ...

From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity. The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill. The clinker store is usually capable of holding several weeks' supply of clinker, so that deliveries to customers can be maintained when the kiln is not ...

Clinker C3S contents of up to ±67 per cent in grey cement clinker can be achieved by raising the lime saturation of the clinker towards 100 per cent. Beyond 100 per cent lime saturation the additional lime will be present as free lime and there will be no additional C3S. That is easy enough for any cement chemist to do, albeit at the cost of ...

Cement is manufactured from organic materials heated together at high temperatures to form a rock-like solid. Chunks are then ground into a fine powder. ... As materials move through the kiln, a series of complex reactions take place resulting in a new substance called clinker. Clinker leaves the kiln as grey balls about the size of marbles.

Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

Sulfate Resistant Clinker – The composition of this type of clinker is alite 76%, belite 5%, tricalcium aluminate 2%, tetra calcium aluminoferrite 16%, and free calcium oxide 1%. In recent years the production of this type of clinker has diminished as it is now possible to get sulfate resistance by making use of granulated blast furnace slag in cement manufacturing.

A number of phases are formed in the clinker feed before the burning zone proper is reached. These intermediate phases dissociate in the burning zone and are not therefore found in clinker but assist in forming the final clinker minerals.
