Vibrating Feeders and ScreensAt Star Trace, 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. Vibrating feeders are used in processing industries for handling various types of materials such as hot, damp, lumpy, dusty or abrasive and used for various functions such as flow of material from storage, proportioning and blending, packaging, mixing, weighing, sprinkling, screening, scaling, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc. We supply vibrating feeders 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. These feeders have 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 externally with the help of a knob provided in the control panel.
The Vibratory Feeders are available in a variety of trough sizes and shapes as per IS: 8723-1978. These 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 variance 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 powerful electromagnetic coils, which is made from double fiberglass 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 pressures.
Electro Mechanical FeederWe develop heavy duty vibro motor powered vibratory feeder that is a high frequency reciprocating machine of heavy duty, capable on conveying bulk material from storage to processing or between processes at a continuous controlled rate of flow. Vibrating feeders are used in processing industries for handling all types of materials such as hot, damp, lumps, dusty or abrasive for various functions like flow of material from storage, proportioning and blending, packaging, mixing, weighting, sprinkling, screening, scalping, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc. We supply heavy-duty vibrating feeders with base mounted over hanging or combined single motor drive or with twin dual or dual twin motor drives or with multiple drives to serve as vibrating conveyors. These feeders are having a tray mounted on the drive units. This unit is located beneath the tray. Vibratory motors used in vibro feeders are totally enclosed 3 Phase, squirrel cage induction motors with adjustable, eccentric weights mounted at both the ends of the shaft to set up vibration during rotation. The design of shaft and the selection of bearings have been carefully done to withstand heavy radial loads. Two identical motors mounted parallel to each other on a right and left, which is free to move in all directions, will produce linear vibrations. When connected for contra – rotation , this principle is adopted for handling large bulky material in large feeders. This vibrator motor stator frame is fabricated in steel or cost in steel or cost in spheroidal graphitic iron and the windings / connections, properly reinforced to with stand the heavy vibrating forces. Vibrator motors can be adopted for conveyors and feeders for handling large quantities of materials is moved by liners force along with conveyor. Usually vibrator motors are fixed at an angle between 30
0 to 45
0 to the plane of the conveyor. This gives the system both upward and forward motion and horizontal vibrations to the tray that ensures a free, smooth, uniform and volumetric flow to the material that is fully variable. We manufacture heavy duty vibrating feeders in a variety of trough sizes and shapes as per IS: 8723 – 1978. 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 requirement. This can be made dust tight too.
