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 spentabrasives 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 allelectrical supply.

◆ Advantages 
● High-Efficiency Abrasive Recycling
Equipped with a large vacuum pump and high-power motor for heavy-duty continuous operation. It efficiently recovers and cleans steel grit, garnet, copper slag and other abrasives after blasting, minimizing resource wastage and significantly boosting overall blasting efficiency.
● Substantial Cost Reduction
By enabling the recycling and reuse of abrasives, the equipment drastically cuts down on abrasive procurement costs, helping enterprises achieve considerable savings in operational expenses.
● Eco-Friendly & Clean Operation
Recovered abrasives undergo thorough cleaning and filtration, effectively reducing environmental pollution and greatly improving the cleanliness of the workplace.
● User-Friendly Operation
Boasting a streamlined structural design, the equipment is incredibly easy to operate. Workers can master its use in a short time, ensuring a highly efficient and stable production process.
● Significant Labor Savings
Adopting high-pressure suction by vacuum pump, it enables long-distance conveying of used abrasives (from blasting rooms, vessel tanks, ballast tanks and other work sites) directly to the storage silo after blasting. This eliminates the need for heavy manual handling, significantly reducing labor intensity.

◆ Industry

To recovery steel shots, grits and garnet after blasting and widely used in the industry of shipbuilding, ship repair, big tank internal blasting etc.

◆ FAQ

What types of abrasives can an abrasive vacuum recovery machine handle?
