Electromagnetic vibrating feeder is a more complete elastic system of double-degree-freedom directional forced vibrations. The whole system works in low critical resonance, it has a feature of simple structure, stable work and small power consumption, widely used in cement industry. Adjustment of electromagnetic vibration feeder is mainly the adjustment of the core electromagnet gap, spring plate of double-degree-freedom connection.1. Double-degree-freedom connection spring plate:The amplitude of trough has two factors: one is the size and frequency of electrical vibration the second is self-resonant frequencies of feeding machine. According to the principle of mechanical vibration resonance, we know that when self-resonant frequencies of feeding machine and vibration freq
