Key Data Set Information
Location CN
Name
clinker production;clinker;ordinary rotary kiln, wet process long kiln
Use advice for data set The data set covering the ordinary rotary kiln process for clinker production is specific to the calcination of cement and is intended for the assessment of environmental impacts in Life Cycle Assessments (LCAs). Users should be aware that this data reflects a specific technological configuration and may not be applicable to other kiln types or differing operational settings. When utilizing this data, users should ensure that it matches the technological and geographical context of their assessment and account for any variations in fuel mix, raw material composition, or environmental regulations that may apply.
Technical purpose of product or process The ordinary rotary kiln process described is used for the production of cement clinker. This industrial process is typically employed in the cement industry for the calcination step, which is crucial for the transformation of raw materials into cement clinker. This type of kiln is appropriate for large-scale production and is known for being utilized in both wet and dry cement manufacturing processes.
