| Use advice for data set | When utilizing this LCA data set for the NSP kiln's cement production process, consider the efficient and continuous nature of the system, as well as its high output and low energy consumption. Special attention should be given to the advanced dust collection and noise reduction technologies implemented, which contribute to the reduction of resource consumption and emissions. Users must account for these factors when comparing this process with less efficient alternatives, such as the shaft kiln. The data set specifically pertains to the milling phase, and users should ensure that the system boundary is properly defined and maintained in their assessments. |
| Technical purpose of product or process | The NSP kiln's cement production process is designed for the manufacturing of Portland cement, a commonly used binder in various types of construction. The high-efficiency milling phase where clinker, gypsum, and other materials are ground is specifically employed for the production of high-quality cement, suitable for construction projects that require reliable and durable cement. |

| General comment on data set | In the cement-milling phase for the new suspension preheater (NSP) kiln, clinker, gypsum, and other mixed materials are milled together into particles of a certain size, and the final product as cement is formed. In contrast with the shaft kiln, the clinker in the NSP kiln stems mainly from the “continuous baking and grinding” phase (100 tons/h), with only a very small part originating from the clinker storage of the previous production phase (2 tons/h). The total clinker thus amounts to 102 tons/h. The input in the NSP kiln contains no water.The NSP kiln is a production system of high efficiency, good production continuity, high output, and low overall energy consumption. In addition, with better dust collection and noise elimination equipment, the production system of the NSP kiln can greatly reduce the consumption of resources and pollutant emissions. |
