Image Number 7 for United States Patent #4449331.
A shot blasting module is adapted for communicating assembly with a blast cabinet module. The slot blasting module comprises a casing housing at least one hoodless abrasive throwing wheel assembly, preferably door mounted, an abrasive/contaminant separator, and a two-stage vertical conveyor. The conveyor is an endless belt with two parallel rows of buckets, one of which directs spent abrasive and contaminants delivered from the blast cabinet module into the shot blasting module into the separator, while the other row simultaneously delivers clean abrasive into a storage hopper from which it is directed to the throwing wheel assembly. A dust collector module is preferably combined with the shot blasting module and the blast cabinet module.
