Shotblasting 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 uses the shot blasting concept.
1. Pneumatic blasting
2.Airless blasting.
Pneumatic blasting machines uses the compressed air for blasting. And the pneumatic sand 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 the abrasive media, in most cases any type of dry or free running abrasive media can be used.
Airless blasting is also called wheelblasting. Wheelblasting machine uses a concept that directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. The capacity of turbine wheel goes from approximately 60 kg per minute up to 1200kg/min. With these large amounts of accelerated abrasive, wheelblast 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.
