摘要

Stone impact simulation device for testing the stone impact resistance of paint layers comprises an air blower arrangement and outlet tube into which granular material can be inserted. The opening for inlet of the granular material is connected to a dosing device for the granular material, which is filled with a predetermined amount so that the granular material can be continuously ejected for a predetermined time interval.
