Vibrating feeders

Duplex vibrating feeder is used for transferring bulk materials from hoppers or storage silos, driers, mixers, grinders, crushers, millers or screens in food processing, chemical, mining, foundry, quarrying and iron and steel industries. Construction features: vibratory feeders are electro magnetically driven conveying devices used principally for feeding material from hoppers. They are mounted immediately underneath the opening of the hopper and as soon as the feeder tray is set vibrating, it produces uniform flow of material. Duplex vibratory feeders are constructed in the simplest way. The two main parts are the electromagnetic activating device and the tray connected rigidly to it. The magnetic vibrator has no bearings or points to be lubricated and thus operates without wear or need for maintenance.
