Electromagnetic Impact Type Vibrator consists of main body that houses the coil. The coil is fed with periodic current that sets in the vibration. Controlling the input voltage can control the magnitude of vibration are easy to install and use and need no maintenance. These are perfect for declogging of hoppers and chutes used for conveying products. Applications are in various industries for: inclined discharge chutes to an easy flow; rectangular or cylindrical bin with centre discharge; effective packing of fluffy and difficult to handle powders in chemical and pharmaceutical industries; and suitable flow of material in conical shaped hopper. These vibrators are manufactured in various power ratings ranging from 25 to 500 w are produced to operate at 230 v ac single-phase system.
