The conventional method of recovering spent abrasives is both labor intensive and time consuming, while the fastest and most cost-effective method of cleaning up spent abrasives is by vacuuming recovery.
Working Principle
Vacuum recovery system is designed to recover spent recyclable abrasives from a blasting area into a silo for subsequent return to the blast cleaning equipment or, in the case of expendable abrasives, for disposal into a waste hopper. After depositing the abrasive into the silo, the vacuum flow containing air and dust continues on to the suction unit, where the dust particles in this stream are removed by high performance filter cartridges prior to exhausting air to atmosphere.
Standard Safety Features
- System automatically shuts-off to prevent damage to the vacuum producer when the suction hose is choked up with abrasives and when the electric motor’s current rises above a certain pre-determined value.
- Cyclone is equipped with full-tank sensor to shut down the vacuum machine when it is full and prevent overloading of abrasives in the dust collector. Silo full-tank sensor available as an option.
- An emergency ‘STOP’ button, when depressed, will automatically cut off all electrical supply.
Application
To recovery steel shots, grits and garnet after blasting and widely used in the industry of shipbuilding, ship repair, big tank internal blasting etc.
