2.
Loss of direction control of 2.
the blast pattern. This will
cause abrasive to strike
sections of the blast
chamber rather than the
work to be blasted,
increasing cleaning time,
wear and maintenance.
b. Check abrasive for dirt or other
contaminants which should have
been removed by the separator.
c. Check separator adjustment.
d. Check feed lines for obstructions
that could reduce flow through the
feed spout or abrasive valve.
Clean or blow out if necessary
e. Check impeller for wear. Replace
if necessary.
f. Check motor and blast wheel
rotation for proper operation.
g. Make sure wheel is not
overloaded with more abrasive
than it can handle. Check and
adjust the abrasive valve
accordingly.
h. Check screens for any
accumulation of objects or debris
that could disrupt the cycle of
abrasive flow.
Conduct an accurate blast pattern test.
Check the "hot spot" location and
adjust control cage accordingly. The
"hot spot" should be directed onto the
work to be blasted at the most
beneficial angle. Inspect control cage
and impeller for wear. Replace if
necessary.
1. Improper sealing.
1. Maintain and replace all worn seals in
the blast wheel housing and feed spout.
Check chamber seals and replace if
necessary.
2.
Worn liners.

2. Inspect liners on a daily basis and
replace when necessary. If liners are
allowed to become too worn abrasive
wear or damage could occur to the
blast wheel housing, blast chamber or
blast doors allowing abrasive to leak
out.
