ABSTRACT:
A shot blasting apparatus rotatable about a caterpillar tractor has a rotor, fed recirculated shot via two screw conveyors, which hurls shot at the ships bottom at an angle optimal for collection and sorting of the reflected shot debris and dust. Shock absorbingly supported at the top of the blaster is a casing, magnetically held to the ship, which is slidably supported in a box so as to "float" weightlessly. A bag filter and fan, mounted on the tractor, extract dust and debris from the shot blaster.
