What types of sand are used in sandblasting machines?

There are many types of abrasive materials commonly used in sandblasting machines, each with its unique physical properties and applications. The following are some common abrasive materials for sandblasting machines: I. Garnet Abrasive Garnet is a red, wear-resistant abrasive material made from garnet ore. It is naturally environmentally friendly, mainly composed of aluminum oxide. It has a low breakage rate and a certain degree of toughness, allowing for recycling and reuse. Uses: Sandblasting for rust removal, cutting, grinding, and polishing. It provides good sandblasting and cutting effects while effectively controlling sandblasting costs. II. Silica Sand Abrasive Silica sand abrasive is mainly composed of silicon dioxide, consisting of silicate minerals. Its characteristics include high crystal hardness, chemical stability, high temperature resistance, and corrosion resistance. Uses: Removing heavy paint and rust, suitable for comprehensive sandblasting processing of ships, railway vehicles, buildings, and stone. III. Iron Ore Sand Abrasive Iron ore sand is mainly composed of iron oxide, with high hardness and good toughness. Uses: Often used for sandblasting metal surfaces, especially in the steel and aerospace industries. These are three common mineral abrasives that can be found in many sandblasting applications. With the development of technology, their uses will undoubtedly become even more extensive in the future.
