Electromagnetic vibrating feeder is mainly divided into linear trough reciprocating type (referred to as straight trough type)And the spiral groove twist type (referred to as the disc type), the working principle of the two is basically the same.

Straight trough type is generally used for the feeding of powder and granular materials without directional finishing, or for the cleaning, screening, drying, heating or cooling of materials; disc type is generally used for materials requiring directional finishing The feeding material is mostly used for the transportation of materials with a certain shape and size. The structure is shown in Figure 1. It consists mainly of a trough, an electromagnetic exciter, and a damper. The exciter is composed of an electromagnet (iron core and coil), an armature and a main vibration spring installed between the two, and is an excitation source for generating vibration. The operation of the exciter can be controlled by a certain control device.
