Shot blasting machine is used used to clean, strengthen (peen), or polish metal. Shot blasting is used in every industry that uses metal. The industries including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others use the shot blasting concept.
Types of shot blasting machine
1. Pneumatic blasting
2. Airless blasting.
Pneumatic Shot Blasting Machine
Pneumatic blasting machines use compressed air for blasting. And the pneumatic shot blasting machine can take the form of a shot blasting cabinet also. The shot blasting media is pneumatically accelerated by compressed air and propelled by nozzles onto the component. For some special applications, a media-water mix can be used, this is called wet blasting.
In both air and wet blasting the shot blasting nozzles can be installed in fixed positions or manually operated. The shot blasting task determines the type of abrasive media, in most cases, any type of dry or free running abrasive media can be used.
Airless Shot Blasting Machine
Airless blasting is also called wheel blasting. A wheel blasting machine uses a concept that directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. The capacity of the turbine wheel goes from approximately 60 kg per minute up to 1200kg/min. With these large amounts of accelerated abrasive, wheel blast machines are used where big parts or large areas of parts have to be derusted, descaled, deburred, desanded, or cleaned in some form.
There are many types of shot blasting machines like fully automatic shot blasting machine, semi-automatic type shot blasting machine, table type shot blasting machine, hanger type shot blasting machine, etc.
Applications of shot blasting machine
1. Rust removal
2. Paint removal
3. Descaling
4. Deburring
5. Texturing on steel/glass
