Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Ground calcium carbonate is widely used in industries such as papermaking, plastics, rubber, coatings and building materials, as well as in fields such as chemicals, food and pharmaceuticals; calcium carbonate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy, waste and air emissions of the production process, and infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes feeding, crushing, screening and other process steps.
Activity Description
The production activities of this product include feeding, crushing, screening and other processes.
Process Description
The chemical formula of calcium carbonate is CaCO3, and its CAS number is 471-34-1. Calcium carbonate is a common inorganic salt. According to different production methods, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate and other types. Among them, heavy calcium carbonate is an inorganic powder made from ground natural carbonate minerals, such as calcite, marble, limestone, etc., and is widely used in papermaking, plastics, rubber, coatings, building materials and other industries as well as chemical, food and pharmaceutical fields.

Technology comment
Dry grinding is the mainstream technology for the production of heavy calcium carbonate. It relies on the physical processing of natural calcite and other ores and has the advantages of low cost and low energy consumption. It accounts for more than 85% of the domestic heavy calcium carbonate market and is a representative technology for non-metallic mineral powder processing. This data set represents the mainstream technology: calcite, marble, limestone, etc. are input as raw materials, crushed using a crusher, and then screened by a screening machine to obtain the target product, and the separated large particles are returned to the crusher for reprocessing.
