In a dry limestone mill, the limestone processing flow is as flows: Grinding: grind the purchased limestone fragments with particle size less than 20mm in the dry-type limestone grinders. Classification: use a classification device to pick out the qualified limestone powder and send the coarse ones back to the limestone grinder for regrinding.

Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.
