Effect of grinding method and particle size distribution

1. Introduction. The cement industry plays an important role in the world economy. But these years it has faced many challenges because of large volumes of CO 2 emitted in the manufacture of Portland cement clinker. According to Allwood et al. (2012) approximately 19 of the global industrial emissions are due to cement production.Life cycle assessment models have shown that one ton of CO 2

Cement millWikipedia

The emergence of Portland cement in the 1840s made grinding considerably more difficult because the clinker produced by the kiln is often as hard as the millstone material. Because of this cement continued to be ground very coarsely (typically 20 over 100 μm particle diameter) until better grinding technology became available.
