We developed a computer model to calculate CO 2 emissions from an ultra-fine grinding process to upgrade fly ash.. Current upgrading of fly ash with ultra-fine grinding processes produces net CO 2 emission reductions when fly ash is used.. Upgrading processes with specific energy consumption under 3.98 GJ/tonne of fly ash can produce CO 2 reductions. ...The principal difference is the point of feeding fly ash in VRM systems. VRMs have built-in high-efficiency separators. Fly ash, being a naturally fine product, can bypass the mill and be fed to the separator at the mill. The roller press and ball mill combination is also being adopted in a variety of ways to make cement. 1.14
