Use advice for data set When using this dataset for Life Cycle Assessment (LCA) of cement produced with alternative constituents in a shaft kiln, note the specific conditions such as the percentage of alternative materials (21-35%) and the energy consumption characteristics of the production process. Consider the technological applicability to the targeted region or industry. Ensure inclusion of all relevant inputs and outputs in the system boundary for accurate representation, and account for high dust emissions in the environmental impact assessment. Avoid extrapolating the data to processes different from those described, such as those using rotary kilns, which may have different technological and environmental profiles.

Data set use approval

General comment The clinker from the cement kiln, mixed together with gypsum and other additives, is milled into fine particles of a particular size in the cement milling sub-system, which are a final product of cement. This phase consists entirely of physical processes; no chemical processes are involved.

Technical purpose The technical application of this data set is targeted towards the cement milling industry. The described cement milling process involves grinding clinker produced from a shaft kiln, with the inclusion of gypsum and alternative constituents ranging from 21-35%, into a fine powder to achieve the final cement product. This milled cement is generally used for construction purposes, including concrete production, infrastructure development, and building construction. The process is characterized by physical grinding without any chemical reactions and refers to production lines associated with vertical kilns, which typically have high energy demands and low production efficiency.
