3.7 Blast wheel
The heart of the blast cleaning machine are two blast wheels that
throw the abrasive onto the surface to be cleaned by using centrifugal
force. The blast wheels are placed in a protective housing lined with
replaceable wear parts. The blast wheels are driven by two hydraulic
motors.
Fig. 3.3
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, which once it is carefully set,
regulates the flow of abrasive.
