Electromagnetic vibrating feeder from the structure is divided into a reciprocating linear trough (the straight trough) and spiral chute twist style (the disc) categories, both works basically the same. Straight groove oriented generally used without finishing powder, granular material feed, or the material used for cleaning, screening, drying, heating or cooling operation of the machine; disc generally used for finishing materials required orientation feed, and more for the occasion with a material transport of certain shapes and sizes. Structure shown in Figure 1, mainly composed of the trough, the electromagnetic exciter, absorber composition. Exciter again by the electromagnet (core and coil), mounted between the armature and the main vibration feeder manufacturers like spring, is vibration excitation source, the exciter can be done in a certain The control means controls. Regulation of electromagnetic vibrating feeder feeder when feeding capacity is proportional relationship between the frequency and amplitude of vibration, but only when the excitation frequency feeder vibration and resonance frequency equal to happen, the maximum amplitude of vibration trough feeder, but this time the stability of the electromagnetic vibrating feeder working poor. To make both steady job feeder feeder suppliers, but also high efficiency vibrating feeder pictures, general electromagnetic vibrating feeder should be adjusted to work in sub-resonance region, ie for more than two frequencies ì = ω / ω0 = 0.85 ~ 0.95, wherein: the vibration frequency ω-- systems, s-1; ω0-- system natural frequency, s-1. When ì value below this range, the trough amplitude smaller feeder transport capacity decreased, increased energy consumption; and ì higher than this range of values ??(supercritical state), feeder working condition will continue to deteriorate finally can not work properly. If the electromagnetic vibrating feeder is not Asian resonance region to work on the elasticity of the system must be tuned.
