Our client is a railcar repair facility located in the United States. We added a second 100HP vacuum unit to their existing grit recovery system.
Client wanted to use existing recovery system under the rails. It was important to have sealed connection from the vacuum unit. This will prevent overflow from backups. A unique grit dispersal system was created. This stops overloading the screw auger on the main recovery chute.
Use existing recovery system.
Generate considerable savings.
This is the second vacuum unit purchased by client. They are both used daily and working great. Client is happy with the product. They salute BlastOne for exceptional workmanship and quality.
WHY USE A VACUUM SYSTEM
Half of a blasting project’s cost is abrasive recovery. Rising labor costs add to the need an even more efficient recovery system. A man, a shovel and a wheelbarrow is now too slow. To increase the recovery rate, use a vacuum system. Power for these systems is diesel or electric. One operator can now recover as much spent material in an hour as six operators could previously. Systems are available to recover from 5-50 t/hr. Recovered abrasive can be recycled or disposed of. With a vacuum recovery system, you can transfer new abrasive into a storage hopper or blast machine.
FREQUENTLY ASKED QUESTIONS
How much compressed air will I need?
You will need 350-900 cfm for Vacuload I and IV. Ideally, use a separate compressor than the blast pot’s compressor. Vacuload VI and VII have an on-board compressor. This pulses the dust collector. The recovery vacuum is created by an on-board blower.
How close does the vacuum need to be to the collection point?
The closer you can get the vacuum to the collection point. Anything more than 2 or 3 200′ lengths of vacuum hose should be avoided.
Does the spent abrasive collect in away that aids efficient disposal/reuse?Commonly 3 options are available for collecting the spent abrasive.
- Into a 44 gal. drum.
- Into a bulk bag.
- Directly into the blast pot.

- IV Vacuload – 4 to 6″
- VI Vacuload – 4 to 6″
