Key Data Set Information
Location CN
Name
clinker production;clinker;ordinary shaft kiln
Use advice for data set This data set should be applied when modeling the environmental impacts associated with the production of cement clinker in an ordinary shaft kiln. Users should note that technological advances and efficiency improvements may alter the impact, and as such the data should be critically reviewed if used for conducting a life cycle assessment of modern production facilities. When using this data, consider including the emissions and energy consumption associated with the raw material extraction and transportation, as these are critical aspects of the clinker production process.
Technical purpose of product or process This data represents the production of 1 ton of cement clinker using an ordinary shaft kiln, a type of industrial kiln used in the cement industry. The clinker produced by this process serves as an intermediary product which is subsequently ground to produce cement. This is the most essential ingredient in concrete, which is widely used in construction for making buildings, bridges, roads, and various other forms of infrastructure.
