Vibrating feeders and screens electromagnet powered vibratory feeder is a high frequency reciprocating machine of light duty capable of conveying bulk material from storage to processing or between processes at a continuous controlled rate of flow. This vibrating feeders are used in processing industries for handling al types of materials such as hot, damp, lumpy, dusty or abrasive for various functions like flow of material from storage, proportioning and blending, packaging, mixing, weighing, sprinkling, screening, scaling, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc. These feeders are having a tray mounted on the drive units. This drive unit is located beneath the tray consisting of two sets of leaf springs connected to the mounting bracket. , an electromagnet with armature and solid cast iron base. When the magnetic coil of the feeder is energized it gives horizontal vibrations to the tray which ensures a free, smooth, uniform, volumetric flow to the material that is fully variable from dribble to surge by externally steplessly with the help of a knob provided in the control panel. Vibrating feeders can be supplied with base mounted, over hanging or combined single magnet drive or with twin, dual twin magnet drives or with multiple drives to serve as vibrating conveyors.
Star trace vibratory feeders are available in a variety of trough size and shapes as per is:8723-1978. This feeders are supplied through a half-wave rectifier resulting into 3000 vibrations per minute at 50hz. The amplitude of vibrations can be varied to vary the feed rate externally with the help of variac provided in the control panel. As there is no moving mechanical parts inside the power unit such as gears, motors, eccentric weights, chains and bearings, there is absolutely no maintenance and no down time for process industries. The vibratory tray is heavily fabricated duly stiffened with angles. Wear resistance plate can also be provided in the tray for varying abrasive materials. Tray can be made to suit individuals requirements. This can be made dust tight too. The system is fitted with a powerful electromagnetic coils which is made from double fibre glass covered copper wire suitable for class h insulation for excellent result. The coil is moulded in specially formulated resin to withstand any type of atmospheric.
