Blast MachineThe Model GWB-702T – a
rotary table wheel-blast system with one blast wheel over each half of a
4,000-pound-capacity, 70-inch-diameter turntable – is especially suitable for
batch processing of work pieces that are essentially flat or have limited
vertical surfaces. Each blast wheel is directly driven at a speed of 3,000 RPM
by a 10-HP motor and is capable of throwing approximately 220 pounds of
metallic media per minute in an extended blast pattern up to 36 inches long.
The blast pattern of the individual blast wheels is adjustable, so the twin
wheels are aimed to provide rapid and thorough coverage of components on the
entire surface of the turntable. GWB-702T wheel-blast machines come
standard-equipped with an enhanced shot reclamation system that includes a
tunable cascade air-wash separator to remove dust from the working media mix as
well as an independently adjustable cyclone separator to capture and reuse good
shot or grit that would otherwise be carried over to the dust collector. The
sensitive multi-stage reclaim enables the use of microscopic shot media for
nondestructive cleaning applications.
