Tumble blast machine with rubber belt is ideal for mass-produced parts, which can be tumbled and will perfectly meet your requirements for batch cleaning, decoring, descaling, deflashing, deburring, and shot peening parts. They are mostly used for process ferrous and non-ferrous castings, forgings and heat treated parts.

Shot blasting machine type GG can be integrated to a fully automatic process with addition of loading and unloading equipment. Tumble blast machines are built in size that can accept single fill / load up to 1,000 kg (volume 500 l).

GG blasting machines have a rubber belt conveyor. When the belt moves its special shape causes treated objects to turn and roll, which causes the whole surface of the treated objects to be quality blasted in a jet of abrasive. For emptying the blasting machine, the belt rotation is switched in the opposite direction turning mode. When the blasting machine works in automatic mode the treated objects are loaded into the blasting machine by hydraulic skip loader, tailored to the customer’s specific component containers.

The discharged pieces fall onto vibratory or belt unload channel conveyor and are transported to the next operation. The GG shot blasting machine’s housing is protected by wear-resistant manganese steel liners. High efficiency of the tumble blast machine is enabled by the continuous abrasive handling and reclamations system for continued returning and cleaning of shot blasting media, along with efficient blasting wheels made from wear-resistant materials. Standard equipment of larger tumble blast machines includes: PLC, display, timer, automatic or manual mode, automatic start-up of throwing wheels, working-hours counter, etc. GG shot blasting machine may be equipped with variable frequency drive for the blasting wheels.

All shot blasting machines have installed ir wheels, which can be upgraded to ir sm@rt wheel. In combination with ir sm@rt valve the operation of shot blasting machine is more effective and optimal.

Gostol TST installed many shot blasting machines all over the world. If you would like to know where our shot blasting machines are installed check our references.
