In this paper Aumund, recent winner of the Global Slag Equipment Innovation Award 2007, showcases its broad range of GBFS and GGBFS handling, conveying and storage options.
During recent years the cement industry has suffered significant increases in operating costs driven in particular by spiralling energy prices plus pressure from environmental lobbies to reduce dependence on fossil fuels and reduce CO2 emissions overall. Considering that the production of a ton of conventional Portland cement generates almost a ton of CO2, and in terms of total greenhouse gas emissions for all industries worldwide, this places cement second only to the power industry in the scale of global polluters.
These factors have generated an increased awareness of alternative fuel possibilities for kiln firing and substitute raw material options for cement production, also reflecting an increased demand for blended cements particularly including ground granulated blast furnace slag (GGBFS). This last point is particularly important; for every ton of GGBFS included in the final blended cement the total CO2 production is reduced by around 1t.
