Star Trace electro vibrating feeders are used in processing industries for handling all types of materials such as hot, damp, lump, dusty or abrasive for various function like flow of material from storage, proportioning and bending, packing, mixing, weighting, sprinkling, scalping, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc.
Known for their corrosion resistance and high performance, heavy-duty electro vibrating feeders is used to increase the bulk handling productivity with controlled high feed rates which further results in improvement of cost-per-ton handling efficiency. These electro vibrating feeders includes electromechanical vibratory feeders, inclined vibro grizzly feeders, vibratory furnace charger. These are ruggedly constructed to minimize the maintenance and improve the production efficiency.
All our electro vibrating feeders needs separate controllers and have very dependable, flexible solid-state control. The feed rates are adjustable and the response is prompt. The electro vibrating design offers durable and reliable service. Drives are encased in dust-tight housings. Controls include a simple rheostat type variable speed controller.
The Electromagnetic Vibrating Feeder has controllers and is dependable in continuous operation. The feeder rate can be adjusted and the Electromagnetic Vibrating Feeder responds promptly to changes made. The use of quality material and skilled work force ensures durability and service for long duration. Electromagnetic Vibrating Feeder drive is enclosed in a dust proof housing. A simple rheostat kind of speed controller is included for control operations.
With an appropriate deck slope, high-frequency vibration affords conveying speeds as high. This vibration is maintained even with varying line power fluctuation.
ELECTRO VIBRATING FEEDERS OPERATION:
Electrical pulses in the coils create a series of magnetic pulls that attract the armature and the deck. Restoring forces in the bar oppose each pull, causing the armature to spring away from the magnet. At an electrical frequency of 60 cycles per second, the armature and the deck operate at 3,600 times per minute (the vibration rate of the feeder). Material is moved by a series of "jumps" that correspond to the frequency of the vibrations. The distance the bars travel can be changed by varying the voltage to the coils. With this variation in the length of each "jump," or vibration amplitude, the conveying speed of the material on the feeder deck changes, resulting in a capacity rate that fits your requirements.
These can take one of four forms, bonded rubber mounts, hollow rubber mounts, helical coil compression springs or helical coil tension springs. The type of mount is selected to suit the requirements of the installation and to provide a minimum isolation efficiency of 95%.
The range of Hopper Feeders have been designed as a self discharging bulk storage hopper capable of storing and then discharging components or materials in a controllable, continuous stream. Particularly suitable for components or products that tangle or do not feed well from static hoppers, the hopper feeders eliminate many of the interruptions in production that can occur with more conventional systems.
Mode of Operation :
Hopper Feeders are essentially closed two mass oscillation systems, sub-critically tuned. The vibratory drive unit and structure are designed to give an asymmetric displacement of the conveying plane which results in a progressively increasing product velocity towards the discharge end of the hopper. This motion prevents mass flow and creates an untangling and thinning out effect on the material / parts being handled, reducing them to a manageable quantity. Special low frequency, high amplitude units are available for products which are particularly difficult to handle.
