Sand blasting and shot blasting are both mechanical surface cleaning processes and are often confused.Let’s see what’s the difference between and blasting and shot blasting?The main difference between them is that they have different working principles and applications.

Sand blasting takes compressed air as its power and shots the high speed abrasive sand stream to the surface of work piece. Due to the impact and cutting action of abrasive sand, the workpiece surface is completely clean, while the surface quality and mechanical properties are greatly improved.The processed workpiece has better fatigue resistance and adhesion, which helps the coating to be smooth, and the service life is longer.
is to use the centrifugal force of the high speed turntable to throw the steel shot to the workpiece surface.After processing, the workpiece will produce finishing effect, pressure stress, improve the fatigue strength.Compared with sand blasting, sand blasting does not produce silica dust and causes less environmental pollution.
Sand blasting is the main function of surface rust, remove oxide, such as parts after heat treatment, and shot blasting action and function is more.Not only rust, surface oxide, but also improve the surface roughness, remove machining burrs, eliminate the internal stress of parts, reduce the deformation of parts after heat treatment, improve the surface wear resistance, compression capacity, etc.
The decision on which blasting technique to use depends entirely on the materials used in your equipment.Because shot blasting systems blast sand at a higher rate, shot blasting clean systems are usually best for metal surfaces that are more difficult to clean.For example,shot blasting can easily remove rust from a metal surface or peel off paint.Sandblasting, on the other hand, is often used to make finer materials, such as plastics, aluminum, wood, stone, glass, or machinery with sensitive electronic components.
