A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Carbon dioxide capture, utilization, and storage (CCUS) has been identified as an effective method of mitigating anthropogenic CO2 emissions. To date, most research and development has centered on capturing CO2 emitted from coal power plants, as they are the largest point source emitters globally. However, cement and steel plants also emit large amounts of CO2 and are potentially easier ...

It is estimated that decreasing the clinker ratio in production of cement contributes to nearly 37 per cent of targeted CO2 reduction. By promoting PPC and PSC cement in India, more than 85 per cent cement is produced as blended cement or composite cement (which has come into existence during the last 35 years).

Let's say a cement manufacturing plant has total carbon emissions of 1,000 tons, total water usage of 2 million gallons, and total waste generation of 500 tons. If their production output is 10,000 tons of cement, the calculation would be as follows: Environmental impact KPI = (1,000 tons + 2 million gallons + 500 tons) / 10,000 tons.
