Use advice for data set When utilizing this dataset, ensure that all stages from raw meal preparation to cement grinding are included in the system boundaries. The database user should recognize that the functional unit is 1 ton of cement product, which is essential for comparison with other datasets. Methodological attention should be paid to the inclusion of industrial waste treatment and the allocation procedures for co-products and environmental burdens. Users should ensure their LCA studies are consistent with the technological applicability of the equipment and processes described, especially the 'two mills and one kiln' system with high automation and reliability. Keep in mind the advancements in distributed computer control systems which enhance process stability, when modeling use phase behavior.

General comment The conventional production process refers to the normal operation of the rotary kiln.The company's cement production line consists of a vertical raw material mill, a 5-stage preheater, a rotary kiln, and a large ball mill (cement mill) equipped with a roller press, as well as equipment for crushing, grinding, and conveying limestone and gypsum. The production system is referred to as the "two mills and one kiln" system, namely the raw material mill, cement mill, and rotary kiln incineration.

Technical purpose The Portland-composite cement produced using this industrial process is intended for construction purposes, including the production of concrete, mortar, and other building materials. The cement is created through a modern dry process using a rotary kiln and has a daily capacity of 4000 tons. It incorporates complex silicate compounds and a mix of industrial by-products and solid wastes to minimize environmental impacts, aligning with sustainable development principles in the construction industry.
