3.9 Blast wheel
The heart of the blast-cleaning machine is a blast wheel that throws
the abrasive onto the surface to be cleaned by using centrifugal force.
The blast wheel is placed in a protective housing lined with
replaceable wear parts. The blast wheel is driven by a electric motor.

Around the centre of the blast wheel there is the impeller feeding
dosed quantities of abrasive onto the blades of the turning blast
wheel. On top of this is the control cage (with 1 notch) which, once it
is carefully set, regulates the flow of abrasive.
