CEMENT GRINDING SYSTEMS
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.

Clinker size and cement grinding | GCP Applied Technologies
Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

Temperature control: Why it is so important during clinker …
Clinker cooling process. A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.

Better and cheaper cement: Optimising the right clinker …
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.

The clinker manufacturing process
The calcinations of the material begin during this stage, changing its phase to the oxide phase for each component to be ready for the burning process. The burning phase takes place in a rotary kiln. The clinker temperature in the kiln burning zone has to reach 1,500°C and then it is cooled in a cooler by air which decreases the temperature.
