The blast wheel assembly is the heart of every Goff machine. Direct drive units,
each Goff wheel is equipped with 4, 7, or 8 curved blades depending on the wheel
diameter. During the blast operation ameasured flow of abrasive falls continuously through the feed spout intothe impeller, which is rotating insynchronization with the blast wheel. Theabrasive accelerates within the impeller and is smoothly
inserted onto the individual blades through a slot, which is adjusted by
rotating the control cage, determines the direction of the blast stream
and allows the "hot spot" to be easily set. An ammeter measurers
the actual flow of abrasive.
The Goff Difference
Direct Drive Assures maximum energy is optimally used
at all times.
Curved Blades Curved in the direction of the
rotation to provide high velocity and even distribution.
Snap-Lock Blade Design Enables quick and easy removal
and replacement of worm blades.
Blade Weighed prior to leaving the factory to
improve the balance and life expectancy of the wheel assembly, while also
reducing noise and vibration
Fully Lined Wheel Housing With interlocking, cast
Adjustable Valve Allows precise control of abrasive
Change wheel diameter from 12" to 13-1/2" to 15" by
just changing blades.
