...Only from Eriez ERIEZ® Features & Benefits: • Electro-permanent magnet drive • AC operation • Simple controls • Encapsulated coils • “Pinpoint” vibration • Enclosed drive element • Low power consumption Bin Vibrators Hi-Vi Electromagnetic Twelve AC drive units to improve flow of hard-to-handle materials in bins, hoppers and chutes. Eriez’ unique Hi-Vi magnetic drive circuit provides a simple yet powerful solution to difficult material flow applications. These vibrators, with their totally enclosed patented magnetic drive, can be used for applications ranging from the tiniest hopper to huge bunkers with reinforced heavy steel plate and liners. Hi-Vi’s concentrated vibration, with its powerful positive drive in both directions, applies a superior action to bin walls…and results in more economical, more efficient flow of har

Electro-Permanent Magnetic Drive Solid-state or AC voltage regulating controls are available to operate the vibrators with “watchlike” precision. In addition, you get all the features that for years have made Eriez Bin Vibrators the leaders in quality and dependability. The basic simplicity of a drive powered by alternately opposing and attracting magnetic forces assures low maintenance. There are no sliding or rotating parts. Power consumption is low, installation easy. The positive driving force of Eriez units provides stability, control, and unexcelled dependability. AC Operation Vibrators...

D20N-D30N These two noiseless models are ideal for many light-duty applications. This light-duty model operates on the impact principle and provide 3,600 vibrations per minute on 60-cycle current.

Specifications (cont.) D55P-D55S This heavy-duty impact model in the medium size range are available for larger capacity applications. The powerful action of the 55 series makes it a popular unit for the more difficult material moving jobs. This is a rugged model that operates on the “double impact” principle, producing 7200 vibrations per minute from a 60-cycle power supply. It provides a “cushioned” impact and is ideally suited to handling sticky materials as well as fine clinging type materials. Power Supply (50 or 60 Cycle, Single Phase) Power Supply (50 or 60 Cycle, Single Phase) Full Load...

Specifications (cont.) D70U The rugged 70U is the largest of our “double impact” type vibrators. Built for heavy-duty applications, this model is ideally suited for use on large hoppers and bunkers which are constructed of heavy plate. Heavy bracing and liners do not affect the vibrating performance of this unit. Hi–Vi Controls Power Supply (50 or 60 Cycle, Single Phase) No control is needed with Eriez Hi-Vi electromagnetic bin vibrators; just wire into any AC line. Controls are available to provide a precise amount of vibration, if required. They are of the potentiometer or solid state type....

Application of HI-VI Vibrators on Bins Hoppers and Chutes Factors To Consider Parabolic Hoppers Rectangular Hoppers Rectangular Bins with Hopper Bottom The size of a Hi-Vi Vibrator necessary to provide proper material movement depends upon a number of factors – the hopper size, shape, physical construction, thickness of hopper plate, hopper stiffness, type and mesh size of the material to be moved and percent of moisture present in the material. Coarse (20 mesh) and dry materials offer the least resistance and are most easily handled. These same materials ground fine (200 mesh) or containing...

See Technical Bulletin VT-350 0H Mounting Instructions for Eriez Vibrators. Application of HI-VI Vibrators on Bins Hoppers and Chutes (cont.) Conical Hoppers Sheet metal containers in the form of an inverted frustrum of a cone are ideal for providing efficient vibration. The vibrator should be mounted directly to the hopper face about 1/4 to 1/3 of the distance from the discharge to the top. When two units are necessary, they should be mounted diametrically opposite but at a slightly different height and properly phased. Hoppers with Vertical Sides Hoppers with Chute Discharge Mount the vibrator...
