Gypsum Board Production​

Gypsum boards, also known as drywall, are widely used for interior wall and ceiling construction. Gypsum ore is first mined and then ground in a grinding mill to a fine powder. The gypsum powder is then mixed with water and other additives to form a slurry.

The slurry is then poured onto a paper - backed conveyor belt and allowed to dry and harden, forming gypsum boards. The fineness of the gypsum powder affects the smoothness and strength of the gypsum boards. A finer gypsum powder results in a smoother surface and a stronger board.​

 

Grinding mills are also used in the production of insulation materials, such as mineral wool. Mineral wool is made from rocks or slag that are melted and then spun into fibers. Before melting, the rocks or slag are ground in a grinding mill to a fine powder. The fine powder can be more easily melted and processed into fibers. Mineral wool insulation materials are used to reduce heat transfer and noise in buildings, and the quality of the grinding process affects the performance of the insulation materials.​
