ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION
For cement, a cradle to grave assessment is especially difficult because cement has so many end uses, and each use has a unique, often complex life-cycle [6]. Therefore inventory analyses and complete LCAs can be quite complicated [1]. This paper presents the review of the main environmental impacts related to the cement production

Re: Cement mill performance drop when use clinker with ...
Long term analysis proved that the ignition point is not as important as commonly expected for the clinker quality. Smallest changes – even only short termed – in flame diameter have a larger impact on clinker quality as formerly thought. Conclusion: Changes on ignition point and thus movements of the sintering zone have been overrated.
Portland cement and the environment - Concrete
Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
