The electromagnetic vibrating feeder uses electromagnetic method to make the feeding hopper vibrate, so that the material (generally belonging to the granular shape) moves in one direction to achieve the purpose of uniform feeding. The feed rate should be relatively balanced with the use. To do this, the feed rate needs to be adjusted.

The feed rate is related to the power frequency, the magnitude and magnitude of the magnetic force. Since the power frequency (50HZ) is generally used, it is often achieved by adjusting the current (or voltage) applied to the electromagnet.

"There is a thyristor in the controller, and the potentiometer is adjustable" is for this purpose: adjusting the potentiometer is to adjust the resistance, adjust the conduction angle of the thyristor in the circuit, that is, adjust the supply electromagnetic The current of the iron adjusts the magnitude of the vibration to adjust the feed rate.
