BH Series

Bin Vibrator - Hopper Vibrator

National Air Vibrator Company is a manufacturer of bin vibrators, and vibrating equipment such as vibrating tables and railcar shakers. NAVCO specializes in pneumatic bin vibrators, piston bin vibrators, air bin vibrators, industrial bin vibrators, and electric bin vibrators, designed to assist in the handling, processing and packaging of dry bulk solid material. Our engineers can develop customized application specific solutions including problem analysis, solution integration into existing processes, and installation recommendations for pneumatic vibrators, piston vibrators, air vibrators, industrial vibrators, bin vibrators, hopper vibrators and electric vibrators.

For trouble-free material flow and discharge from storage bins and hoppers.

Details

High amplitude characteristics of the BH industrial bin vibrators when used as a bin discharger enable the vibrating energy to be transmitted in the capacity required to overcome the strength of the bulk material involved in a bridge (arch) or a rathole (pipe) inside of a bin or hopper. Other advantages of high amplitude, linear vibrators include low utility consumption and minimum bin wall stress.

The unique NAVCO^® Bin Mapping methodology involves a detailed evaluation of the storage vessel and its intended bulk material. Recommendations are made based on a variety of factors including bulk density, particle size, moisture content, temperature, vessel size and shape as well as material of construction. NAVCO^® pneumatic piston vibrators are sized for the application and their area of influence is determined. The vibrators are located on the hopper so that the areas of influence overlap; vibrations are controlled through a sequence that provides optimal flow pattern and minimal utility consumption.

NAVCO^® manufactures a range of sizes and options for the BH Bin Hopper Vibrator for various applications.

Food Safe Vibrator Options

 

The model BH industrial vibrator for bins and hoppers incorporates a nominal piston and bore. During operation, compresssed air is alternately directed from one end of the piston to the other through a series of internal ports. The piston is the only moving part, which makes a pneumatic piston vibrator a reliable, low maintenance device. The bin vibrator housing is a one-piece, ductile iron casting. This adds to the durability and reliability of NAVCO^® Pneumatic Piston Vibrators. The action of the piston in our industrial vibrator generates high amplitude vibration with unidirectional, or linear, force vectors.

The linear vibration of a NAVCO^® industrial bin discharge vibrator offers the following
Advantages:

• The energy generated by the vibrator can be directed normal, or perpendicular to the flow of the bulk material to address a specific material flow problem. The vibrator energy is used very efficiently to reduce the sliding friction angle of the hopper and to overcome the the strength of the bulk material in the hopper. These two factors are key to promoting the flow of bulk solid materials.

• BIN Vibrators that generate linear vibration do not develop high shearing forces at the bin wall. This allows a simple, more direct approach to mounting the vibrators and causes less stress to the bin wall.

• Linear vibration is ideal for driving vibratory feeders and compaction tables too.
