Abstract (en)
[origin: US4680900A] A device for accelerating an abrasive, which includes magnetically influenceable particles, especially iron particles, for the treatment of surfaces. The device is provided with magnet coils, which are used as accelerating elements, are arranged along the path of the abrasive, preferably on a pipe, and are energized or de-energized by the magnetic field maximum as a function of the traversing of the abrasive which moves in the coil field. The first and the second magnet coils at the beginning of the acceleration section have opposite poles, are synchronously energized or de-energized, and take a predetermined quantity of abrasive from a static supply of abrasive and convey it to the next magnet coil for acceleration purposes.
