The difference between shot blasting machine and sandblasting machine

Shot blasting machine and sandblasting machine are two common surface treatment equipment, which differ in principles, abrasives, application scope, equipment complexity, and cleaning effect：

working principle

◆shot blasting  machine：Using a high-speed rotating impeller to project projectiles (such as steel balls, iron balls, etc.) onto the surface of the workpiece, cleaning and strengthening the surface through impact and cutting effects.

◆sandblasting machine：Powered by compressed air, abrasives (such as quartz sand, diamond sand, etc.) are sprayed at high speed onto the surface of the workpiece to achieve the effect of cleaning and roughening the surface.

Abrasive selection

◆shot blasting  machine：Mainly using metal pellets such as steel pellets, aluminum pellets, ceramic micro powders, steel grit, etc.

◆sandblasting machine：Multiple abrasives can be used, including quartz sand, diamond sand, glass beads, ceramic particles, etc

Scope of application

◆shot blasting  machine：Suitable for cleaning large castings and forgings and strengthening batch workpieces, commonly used in industries such as metallurgy and casting.

◆sandblasting machine：More flexible, suitable for precision component processing of various materials, can be used for rust removal, surface modification, etc., widely used in fields such as hardware and rail transit.

cleaning effect

◆shot blasting  machine：The cleaning effect on workpieces is significant, efficient, and can clean multiple workpieces at once.

◆sandblasting machine：Realize precise cleaning and sanding, with high precision, suitable for complex shaped workpieces
