5.Data from Practical Applications:

The application data from a user of shot blasting machine is as follows: steel plate sample: 12mm×500mm×1000mm GLT-500; diameter of steel cut wire shot: 1.5mm; direct shot blasting; projected distance: 700mm; projection velocity: 75m/s; shot blasting time: 100 hours; the longest continuous shot blasting duration: 9 hours; no obvious change of the thickness measured before and after shot blasting at 10 marked test points had been found.
