7.8 Blastwheel blades & Impeller replacement
During operation the blast wheel blades and the impeller will wear.
To replace worn components:
ˆ Make sure the power unit is stopped and the main
electricity supply disconnected.
ˆ Remove the bolts securing the abrasive storage hopper to
the separator and remove the hopper from the machine.
ˆ Remove the cage clamps securing the control cage and
remove the control cage.
ˆ Unscrew the impeller bolt and remove the impeller using a
wooden or brass drift.
ˆ Remove the top liner cover and remove the top liner using
a screwdriver or a crowbar.
ˆ
Clean the blast wheel and the blades with air.
ˆ Through the opening at the top of the blast housing: use a
wooden or brass drift to tap out all six blades from the
blast wheel towards the centre of the blast wheel.
ˆ Clean the blast wheel thoroughly to make sure that the
new blades and impeller will fit well and to avoid any
imbalance of the blast wheel.
ˆ
Replace the blades with six new ones and re-assemble
the machine in reverse order. Note: blast wheel blades
must be replaced as a set. Replacing only some of the
blades can cause imbalance of the blast wheel.
