Vibratory feeder provides stability, control and accuracy

October 7, 2009
The rugged, AC-operated vibratory feeder enables linear, exact feeding of large quantities of bulk materials. The electromagnetic feeders offer a cost-effective, sanitary alternative to screw feeders. The unit is designed for feeding up to four tons per hour and features a totally enclosed, dust- and moisture-resistant patented electromagnetic drive, which extends coil life and makes cleaning easier. The simple AC controls operate the feeder with “watch–like” precision. This innovative feeder features a Hi-Vi Magnetic Drive Circuit, powered by alternately opposing and attracting magnetic forces, which assures low maintenance. There are no sliding or rotating parts, power consumption is low and installation is easy. The Hi–Vi system incorporates a lifetime permanent magnet (part of a spring–mounted moving mass) whose poles are intermeshed with those of an electromagnet powered directly by an AC line. This results in the spring–mounted moving mass being both attracted and repelled by the AC electromagnet equally on each half of the AC cycle.
