After water, sand is the world’s most consumed natural raw material. Since sand is not only needed for buildings or roads, but also for glass, cosmetics or smartphone screens, the demand far exceeds natural resources. For more than 60 years, Hengyang Equipment and Process Design, a leading specialist in wet mechanical processing and environmental technology, has been helping to process different types of sand as a usable raw material for a wide range of industries with its equipment, process units, and plants.
In the glass industry, silica sand is a key ingredient in the production of glass products due to its high silica content, low impurities concentration (typically Fe2O3, Al2O3, TiO2) and physical properties. As such, glass sand generally has a higher purity and a more controlled grain size compared to regular silica sand. It undergoes processing to remove impurities and achieve specific characteristics required for glass production. Glass sand is a critical component in making various types of glass, including float glass, container glass, fiberglass, and specialty glass products.
In the given case, a recent commissioned industrial silica sand project example will be presented.
