Limestone Powder, Calcined Limestone Powder

Limestone Powder: Limestone powder is a general term for the powdered form of stone. There are many types of stone, and they are categorized based on mineral composition, not necessarily calcium carbonate. Calcium carbonate is a type of limestone powder, but there are others, such as talc powder used for making putty. There's also quartz powder, used in glassmaking. Many different types of rocks with various mineral compositions can be ground into powder for various industrial processes and applications.
Limestone powder has a wide range of applications; products made from it are ubiquitous in our daily lives, such as plastics, calcium tablets, clothing, toothpaste, and more.
Ultra-fine Stone Powder: Widely used in the production applications of rubber, papermaking, coatings, plastic aluminum profiles, ceramics, cement, glass, metallurgy, refractory materials, food, daily chemical industry, craft architecture, and high-end decoration. Particularly, when used in coatings and papermaking, it can directly reduce the usage of titanium dioxide by 3-10%, thereby significantly reducing product costs. The application of high-quality marble (dolomite) ultra-fine stone powder in the paper industry is for pulp filling (coated paper, copper plate paper, etc.), which serves to enhance opacity and improve the flexibility of the paper.
