[PDF] Cement grinding optimisation | Semantic Scholar
Abstract The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant ...

Environmental impact of Portland cement production ...
The grinding process impacts the cement manufacture in at least two ways. First, an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions, leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency.

Optimizing cement grinding with chemical additives
Grinding additives contain surfactant chemicals, which absorb on the surface of the cement grains, neutralize the surface charges and shield against the inter-particle attractive forces. Reducing the effects of inter-particle attraction forces of cement grains helps to keep particles from clumping together.

Portland cement and the environment - Concrete
Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.
