Grit shows a clear edge in blasting technology

Plenty of arguments speak in favour of using blasting gravel instead of non-abrasive blasting agents.

Using the appropriate blasting medium is a key cost factor. It's not just about the purchase price for the blasting medium, but also about the consequential costs with respect to the blasting time per workpiece and the wear costs on the blasting system.

Significantly reduce blasting times with grit blasting technology

It might make sense for you to switch the blasting agent from less abrasive blasting media to grit. “It is important here to match the workpiece material and the desired effects of the blasting technology with the blasting medium”, says Jürgen Bächle, managing director of Sigg Strahltechnik GmbH. “In general we offer our customers an evaluation of the blasting process with various parameters. In our test laboratory, we blast sample pieces so that we can achieve a realistic assessment of different blasting media. Grit can reduce the blasting times for the part by 20 to 50 per cent, because the angular material has a much greater effect on the surface”, explains the blasting technology expert. Blasting processes where productivity matters above all should therefore be tested and compared with grit instead of a less abrasive blasting medium.

Calculate system wear correctly

The system wear is an important factor in blasting technology. Grit puts a greater strain on the wear parts of the blasting system than a less abrasive blasting agent and causes costs due to a shorter service life of the system and more frequent replacement of wear parts. On the other hand, the blasting time per workpiece when using grit is usually much shorter so that the service life should be put in relation to the number of blasted parts. This makes it possible to determine the system wear costs per workpiece - and these costs can be much lower due to the shorter blasting time per piece with grit. “Grit has big potential in blasting technology, for example when cleaning cast parts”, confirms Jürgen Bächle.

Grit scores when it comes to corrosion protection

Technical advantages also speak in favour of using grit in blasting technology, because the angular blasting agent provides an optimal cleaning performance and roughness of the surface. As a result, coatings adhere particularly well - even at critical points such as the edges of workpieces. The corrosion protection of the workpieces is significantly improved thanks to the improved adhesion of the protective coatings. This makes grit an ideal blasting medium in many industries.

Summary: Grit is a blasting medium with potential. Reduced unit costs through time advantages with improved cleaning performance and optimal surface properties make for a particularly efficient blasting technology.
