Building materials, why fineness of gypsum is important?

The fineness of gypsum powder is important, because the finer powder, the higher value it has. Gypsum ultrafine grinding machine is mainly used in mining, building materials, chemical, metallurgical and other industries. It can process stone materials that moisture content less than 5%, Mohs hardness under 6 levels, such as kaolin, limestone
