What's the Difference Between Shot Blasting & Sandblasting?
Abrasive blasting is a cleaning method in which a steady flow of abrasive materials is directed at a surface. The process can create a smooth, shiny surface or else reshape it. Both shot blasting and sandblasting are popular abrasive techniques. To decide which method is best for your refurbishing project, learn more about the difference between them.
Shot Blasting
During shot blasting, an abrasive material is put in a centrifugal wheel and directed at the target surface at high velocities. It’s often used on surfaces that require a strong application force, such as steel, concrete, or wrought iron.
Shot blasting must be contained or else the extreme force can damage surrounding areas. For example, the method is contained in a tank for restoring automobile frames or recycling steel containers. Other types of shot blasting machines are ride-on, like a tractor.
Sandblasting
In sandblasting, compressed air is used to propel the abrasive at the target surface. While silica sand used to be the preferred abrasive, it proved to be a health risk. Nowadays, common materials include steel grit and baking soda. This method is favored for cleaning more sensitive materials because it not only cleans the surface but improves its texture. The technique is useful for items being readied for finishing touches like painting or coating. It might also be used to clean grease, oil, or rust, from auto parts.
As with shot blasting, this process is often contained to avoid spreading abrasive materials. The object being sandblasted will be placed inside a sealed cabinet which a technician can access through rubber gloves.
