11.2 DUST COLLECTOR – VENTILATION SYSTEM
Note: Once the Dust Collector has been in operation for several minutes, a
stable operating level will result. Sudden changes in operation can usually be
traced to a malfunction.
Trouble Possible Cause
Remedy
a. Very soft concrete
removal. Excessive dust
quantities entering
system (will cause
excessive component
wear).
a. Increase machine speed to
reduce the amount of concrete
removal or reduce abrasive flow
to wheel.
Contaminated abrasive -
fines and contaminants
not being removed from
abrasive.
b. Check filter: Clean or
change if necessary.
b. Insufficient airflow
being delivered by dust
collector.
a. Torn, punctured or
improperly installed filter
cartridges.
a. Check filters. Replace or
reinstall immediately.
Visible dust discharge.
b. Be sure there is an air tight
seal around the filters. b. Improper filter
installation.
11.3 VACUUM ADJUSTMENT – OPERATING TIPS
For normal concrete surfaces, Blastrac does not recommend using more
than the 25 feet of exhaust hose supplied with the blast system
. Adding
additional hose can cause insufficient suction, which will allow unwanted dust
and contaminants to accumulate in the abrasive, thereby causing premature
wear to the blast wheel and liners. Additional hose can only be added when
cleaning steel surfaces. Contact your Blastrac representative for your specific
steel cleaning application.
Normal shot-blasting with the blast unit will usually be accomplished with the
vacuum adjustment gate partially open. Too much suction will sometimes pull the
abrasive out of the separator and into the dustpan. This is particularly true when
using small sizes of abrasive such as S-170 and S-230. A period of trial and error
may be necessary for specific job applications. Generally speaking, the more
dust generated by your shot-blasting unit, the greater the suction you will need
from the dust collector to keep the abrasive as clean as possible.
