• Effect of chemical composition of clinker on grinding ...

    1999-4-1  There are numerous factors affecting the energy consumption during clinker grinding. Clinker hardness imparts a wide variation to grindability. The hardest clinker takes about 80% more power than the softest one . Furthermore, different fineness requirements result in higher energy consumption.

    2013-7-19  In the cement industry, the clinker grinding step consumes about one-third of the power required to produce one ton of cement. This refers to an average specific power consumption of 57 kWh per ton (Seebach and Schneider, 1986) and specific carbon dioxide emissions intensity for electricity generation of 9.1kg CO 2 per ton (Worrel et al, 2000).

    2014-2-1  Clinker grinding consumes about one third of the total amount of energy needed to produce cement. Moreover, the electricity required to manufacture 1 mT of cement, generates 9.1 kg of carbon dioxide from burning coal. Therefore, a small increase in grinding efficiency can result in significant reduction in operating cost and CO 2 emission.
