The control and feeding of vibrating feeder. It is a double degree directional vibration system. It is hung under the hopper and has a fixed moving space. There should be no stick and impact to get rid of the noise. 
1. After the installation of vibrator, to unlock the screw on the directed yoke and tighten the unlocked screw by nuts. To open the rear cap of the vibrator to make sure the steel core and the armature is parallel and the gap between them is 1.8-2.1 mm. then to tighten the screw and the cap.
2. In the trial run without load, to increase the amplitude potential device “R1” gradually. The range of the amplitude should between 1.8-2.5 mm, and the current flow should 3.5 < A. Trail run should lasts for server
al hours to make sure stable amplitude and the current flow; then to feed materials to test the current and amplitude. The amplitude can varied by the max 0.5 mm, and if the feeder is smaller in capacity under the rated condition, the lean the vibrator by to improve the capacity.
