Environmental Impact Of Portland Cement Production Jan 01, 2013 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 ...

Scenario 3 considers the current lab-scale production, using organic starch instead of regular starch, to assess if it has a positive environmental impact over all. Scenario 4 considers that energy consumption per kg should decrease when scaling up the production process, and the use of organic starch. An estimated decrease of 50 % was postulated.

The grinding limit and its influencing factors are of great interest for nanoparticle production by top‐down approaches. This article deals with the limits of grinding from different points of view (apparent grinding limit, true grinding limit, viscous dampening‐related grinding limit) and emphasizes parameters enabling an energy‐saving comminution process.
