The construction industry is one of the largest consumers of non - metallic mineral powders, and non - metallic ore grinding mills play an essential role in meeting this demand.
Limestone is one of the most commonly used non - metallic minerals in the construction industry. After being processed by grinding mills, limestone powder is used in the production of cement. Cement is the binding material in concrete, and the quality of the limestone powder used in its production can significantly affect the properties of the cement. For example, a fine - grained limestone powder can improve the workability of the cement paste and enhance the strength of the concrete. Grinding mills are used to reduce the limestone to a suitable particle size, usually in the range of 80 - 400 mesh, depending on the specific requirements of the cement production process.
Gypsum is another important non - metallic mineral in the construction industry. Gypsum powder, produced by grinding mills, is used in the manufacture of drywall, also known as plasterboard. Drywall is widely used for interior wall and ceiling construction due to its fire - resistance, sound - insulation, and easy installation properties. The grinding mills ensure that the gypsum is ground to a fine powder, which is then mixed with other additives to form the slurry used in the production of drywall. The particle size of the gypsum powder needs to be carefully controlled to ensure the smoothness and strength of the drywall.
