Apr 01 2013 1. Introduction. The amount of energy used in cement flour production is immense. About 110 kWht is necessary for cement grinding processes Sverak 2004.Given that world cement production in 2011 was 33.0 Mtyear a total of 3.63 TWhyear goes into cement production.This represents 0.018 of all electric energy 20.2 PW hyear produced throughout the world Ch teau
1970 and 2010 primary physical energy intensity for cement production dropped 1.2 per year from 7.3 MBtushort ton to 4.5 MBtushort ton. Carbon dioxide intensity due to fuel . or clinker-grinding plants that intergrind clinker obtained elsewhere with various additives.
EP 2336100 A1 describes additives for mineral binders with reduced browning potential comprising a grinding aid selected from glycols monocarboxylic acids having 1 to 4 C atoms and polycarboxylate ether comb polymers as well as a retarder which can be used in the cement clinker grinding process.
