цитата из описания этого виброконвейера:
The high throw conveyor vibrates at a natural frequency of 18 Hz at 30˚ for a stroke length of 10mm (±5mm) on a dimpled pan, making it an extremely energy efficient solution too.

Vibrating, again by definition, means “to move back and forth rapidly.” The equipment and process solutions described in this guide all use this rapid “back and forth” motion to move or convey product. On a vibratory feeder, material is “thrown” up and forward so that it drops to the surface at a point further down the tray. This is the feeder’s amplitude.
The number of times per minute that this repeats is the frequency. A third variable is the angle of deflection… meaning how high the product is thrown as compared to its horizontal movement.
