Blasting media

Recycling of blasting media saves money, resources and creates a dust-free healthy environment

One of the main challenges in any blasting operation is to avoid the blasting media and residuals from blasted material to contaminate the surrounding work environment. Abrasive blasting needs to be carried out in an enclosure. This is most often done in a dedicated blasting room, separated from other operations, so the work pieces need to be moved to and from the blasting room, or encapsulated, leading to increased operating costs.

Blasting media is also expensive to buy and even more expensive to destruct. Means to minimize the usage of blasting media are therefore important to consider.

Nederman offers solutions that recycle blasting media, with many benefits:

  • The surrounding area remains dust free 
  • Special protective equipment relating to dust becomes unnecessary
  • No cleaning required
  • The piece that is blasted does not have to be moved
  • Blasted material is collected

Save money, resources and create a healthy dust-free environment with Nederman Vacuum Sandblasting equipment

The solution is efficient collection and recycling of blasting media. The recycling of blasting media is an easy way to reduce cost in sandblasting operations. When recycling blasting media a media with longer life can be used to further improve profitability, e.g. steel based blasting media has a life expectancy of up to hundred cycles.

Recycling of blasting media

During blasting the blasting material is ground down, resulting in finer grains. When the recycled media is mixed with new blasting material, a mix of different grain sizes is created. The resulting mix of grain sizes actually gives a more efficient blasting and a smoother finish with fewer cavities, increasing the quality of the finished work piece. Nederman offers solutions for efficient recycling of blasting media.

The blasting media is collected and sent to a separator, which separates dust and other contaminations from the blasting media and returns the blasting media to collection tank, where it is mixed with new blasting media. The vacuum is created by a vacuum producer. The vacuum producer can be either an air powered ejector pump or an electric powered pump or fan. The ejector vacuum producer is the recommended solution and is especially suitable for ATEX environments. The pump has no moving parts and is powered by compressed air through an external air compressor. The separated dust is sent to a filter and is collected in dust bins, big-bags, plastic bag or container. The collection and recycling system can also be fitted with an extra cleaning system.

Nederman "On tool" vacuum sandblasters

The possibility to carry out blasting directly on site without the risk of contamination can greatly reduce operating cost. Nederman offers an enclosed "on-tool" vacuum sandblasters, which collects the blasting material in direct connection of the blasting nozzle. The blasting can be carried out in any location without risk of contaminating the surrounding work area.

Recycling of all approved blasting media , e.g. glass beads and nutshells. The dust generated from the blasting operation is immediately and continuously extracted together with the blasting abrasive to the grit separator that separates the dust from the active blasting abrasive. The air from the sandblaster is purified and can be returned to the premises. No post-cleaning required and all blasted material is collected in a waste bag. The blasting media can be recycled several times depending on media which reduces stoppages. Clean and interruption-free for work colleagues and surrounding area. Vacuum blasting with blasting media recycling can furthermore be used both outdoors and in enclosed spaces where regular sandblasting is not permitted. No need for special blasting rooms.

If a treated surface, e.g. painted surface, is heated up as a result of a welding or grinding operation, hazardous gases, isocyanates are released into the air. There are isocyanates and polyurethane in paint, coatings, adhesives and sealants. These isocyanates can be harmful to the respiratory tract. The concentrations can reach levels that are high enough to cause asthma, making vacuum blasting is an important precaution. All types of blasting abrasive suitable for recycling can be used.

  • Recycle blasting agents and save money
  • Reduce stoppages when operating
  • Dust free and safe
  • Environmentally friendly
