Endurance test glass beads

1. Test planning

1.1 Basic information

Project: Dauertest Glasperlen

Process, devices Suspension Injection | System: 170/10

Pressure [bar] 120 bar

Abrasive (type, size) Al2O3 Garnet glassbeads | Mesh size: 0 - 50µm

Abrasive perc. [m%] Ca. 5%

Nozzle (type, size) Fanjet nozzle 0.76 x 40°

Handling devices yes, type: Kuka KR 3 no (manual trial))

1.2 Test descriptio

By using Suspension Technology, a stainless steel plate was blasted with glass beads and a

stand-off distance of approx. 50mm for an extended time in a closed loop. By analysing the glass

beads optically by a microscope after defined intervals the wear on the beads was determined.

1.3 Parameter

Pressure: 120bar

Stand-off distance: 50mm

2.2 Conclusion

The optical investigation confirms that the glass beads are not fragmented. On the basis of the

surveying photos before and after the blasting no difference in the grain size distribution could

be determined.
