Heavy Duty Electromagnetic Vibratory Feeders

Heavy Duty Electromagnetic Vibratory Feeders

Heavy duty electromagnetic vibrating feeders increase bulk handling productivity with controlled high feed rates that improve cost-per-ton handling efficiency. They provide simple and efficient solutions for complex material handling operations. Adjusting the feeding speed by adjusting the voltage make the feeder stable, uniform and easy control.

Light industry electromagnetic vibrating feeder, consisting of a dynamically balanced, two-mass vibrating system, assembly is an electromagnetic unit. This system consists of a trough and trough connecting bracket coupled to an electromagnetic drive by means of leaf springs, offering excellent durability and reliability. Electromagnetic vibrating feeder are subresonantly tuned to maintain stroke consistency and speed stability, thus delivering higher capacities at controlled feed rates.

Design principle

The principle of electromagnetic vibrating feeder is based on a dual tuning system. The elastic components contained in system are composed of flexible shrapnels. The number of shrapnels determines the resonance amplitude as running. After being excited by rectifier circuit, the magnet core attracts the moving magnetic armature fixed on the tray mutually. After the coil de-energized and the core's magnetism disappear, the kinetic energy accumulated on shrapnels returns the system to original situation.
