The blast wheel method is a revolutionary invention based on a simple principle:
After mechanical pre-acceleration, the abrasive is thrown onto the surface at high speed by the
blast wheel. Once the abrasive has impacted the surface it rebounds into a rebound plenum. The
rebound plenum deflects the abrasive into an air current separator. In this location, dust and other
contaminants are removed from the abrasive so that only abrasive containing a very small amount of
dust is falling back into the abrasive storage hopper to reflow to the blast wheel.
3.4 Dead Man Switch
The dead man switch (1), at the handle opens the
magnetic valve and switches via the incorporated micro
switch (2) the wheel motor ON and OFF.
If the dead man switch (1) is released it goes down
through a feather mechanism, the motor is cut off and
at the same time the magnetic valve is closed and the
abrasive feed is stopped.
In case of an emergency, the wheel motor can be
stopped through the emergency stop switch (3).
