If blast wheel & control cage are aligned probably but
excessive noise persists, it could be that other rotating
parts are coming into contact with each other. Check
bearing units, belts, sheaves, motor mounting, wheel
housing, & any other associated parts to be sure that
they are aligned & safely secured.
The shot blasting
machine is taking longer
to shot blast than before.
It could be one of several problems. First, check to see
how shot is being fed to the wheel. It is important to make
sure that enough shot is getting to the wheel. Second,
make sure storage hopper has enough shot within it.
Third, verify that shot is not contaminated. Shot should
be fairly clean & ventilation system should be working
properly. Fourth, check shot feed & shot control valve.
Obstructions in the shot feed or shot valve can slow
down shot blasting. Fifth, check wheel impeller & control
cage. Excessive wear may warrant replacing wheel kit.
Sixth, investigate drive belt & make sure it has proper
tension, correct alignment, & is not worn out. Seventh,
look to see if blast pattern is still consistent. If it is not,
make sure that the blast wheel is sitting properly in the
wheel hub. & finally, eighth, check the wheel. Make sure
that the shot valve is working properly.
The shot blasting
machine is creating
excessive wear on liners
& blast housing.
Adjust control cage so that the “hot spot” is centered in
work area rather than on liners or housing.
The shot blasting
machine is dropping an
excessive amount of steel
shot.
Verify “hot spot” is centered properly & adjust control
cage as necessary. Verify seals do not have excessive
wear, feed spout is aligned properly, & shot valve is
closing when shot lever is released. Verify dust collector
has adequate suction.
The shot blasting
machine will not move
forward.
Make certain that the drive pin has been installed. Check
wiring plugs & replace any faulty components
The shot blasting
machine is difficult to
push or gets stuck in
areas.
Verify that the seals are positioned properly & that they
are not too close to the floor. Raise height of seals. Pull
up on steering handle to clear small obstructions on the
work surface. Use extreme caution when doing so as this
maneuver may cause shot to shoot out of the machine &
into the work area.
The shot blasting
machine is not blasting
properly.
Slow machine down so that a deeper profile is created.
