Shotblasting Problems & Possible Solutions

Problem:

Breaker is tripping when BP-9-1 10V and dust collector are turned to the ON position.

Possible Solution:

BP-9-1 10V and dust collector should be powered by separate breakers. Find

electric outlets with separate breaker switches and use accordingly. Check circuit breaker sizes.

Problem:

BP-9-1 10V is vibrating excessively.

Possible Solution:

Check blast wheel immediately. Excessive vibration is usually caused by the

blast wheel being out of balance due to it being worn or by blades being broken or chipped.
Install new blast wheel kit. Failure to install new wheel kit in this instance could lead to serious
damage to machine.

Problem:

BP-9-1 10V is creating excessive noise.

Possible Solution:

This problem is most likely caused by an improper alignment of the blast

wheel and control cage. Check alignment of blast wheel and control cage immediately and
verify that there is adequate clearance between the blast wheel and the control cage.

Problem:

BP-9-1 10V is creating excessive wear on liners and blast housing.

Possible Solution:

Adjust control cage so that the "hot spot" is centered in work area rather than

on liners or housing.

Problem:

BP-9-1 10V is dropping an excessive amount of steel shot.

Possible Solution:

Verify "hot spot" is centered properly and adjust control cage as necessary.

Verify seals do not have excessive wear, feed spout is aligned properly, and shot valve is closing
when shot lever is released. Verify dust collector has adequate suction.

Problem:

The blasting performance of the BP-9-1 10V has diminished.

Possible Solution:

Verify that there is an adequate amount of steel shot in the shot hopper and

that shot is free of concrete dust or other contaminants. Verify there are no obstructions in the
shot valve or feed spout and the feed spout is properly aligned. Verify that the shot valve is
opening properly. Verify that the blast wheel and the control cage are not excessively worn.
Verify dust collector has adequate suction.

Problem:

BPS-110V is difficult to push or gets stuck in areas.

Possible Solution:

Verify that the seals are positioned properly and that they are not too close to

the floor. Raise height of seals.
