Model for transport of granular matter on vibratory conveyors vibrating angle = 46:0o, throw number and can be modeled by a velocity IC Feeders, screens and vibrating equipment The steep angle of throw prevents blinding, enabling maximum
FIG. 6 is a view similar to FIG. 5 but plotting stroke versus stroke angle for the opposite conveying direction. DESCRIPTION OF THE PREFERRED EMBODIMENT An exemplary embodiment of a bi directional vibratory conveyor or feeder is illustrated in the drawings and will be described herein as a conveyor, it being understood that the terms conveyor ...
Industrial equipment catalogs classify vibrating conveyors generally by their ultimate application, such as foundry conveyors or grain conveyors, or by their type of duty: light, medium, heavy and extra heavy. The equipment design required for a specific type of service is left up to the manufacturer. It would probably be more descriptive to classify or categorize vibrating conveyors by their drive system and/or constructive method. Depending on the stroke and frequency desired, a choice can be made out of a number of exciter types.

The analysis of the movement of bulk granular materials along the vibrating conveyor trough is a complex mathematical exercise, as it is influenced by many factors related to trough motion and material properties, such as: Trough related : Type of motion stroke angle. Frequency. Amplitude. Inclination angle. Secondary vibrations in trough Shape and smoothness of trough Elasticity of trough liner Presence of electrostatic charges. Material related : Bulk density. Particle shape and size. Size distribution. Internal friction coefficient Sliding friction coefficient. Cohesive strength. Internal damping. Bed thickness. Permeability. Feeders on the other hand, are designed as rugged, relatively small pieces of equipment with great structural integrity and can withstand the high frequency oscillation.
The most common types of drive mechanisms are the a. crank type, b. rotating weights type, c. electro magnecic type. Each of these exciter drive mechanisms can be used in various arrangements of the trough, reaction mass and springs. Each of these arrangements will require different amplitudes, frequency ratios w/wn and exciter forces, and will result in different power consumptions. Depending on the manufacturer, some difference of opinion exists as to the desirable frequency ratio w/wn. The closer w/wn is to 1 the larger the magnification factor for the amplitude, and therefore the flow rate of the solids. It would appear that one can increase solids flow rate without increasing the horsepower or energy consumption. This is not true. The old adage is still valid that you cannot have something for nothing. Factors such as material damping, spring hysteresis, motor drive characteristics, etc. influence the performance of the vibratory conveyor or feeder. Therefore, care should be...
Reduced Sound Levels: Reduced sound levels are another benefit of Kinergy Vibrating Conveyors. Our Conveyors typically operate less than 80 dBA in the loaded condition. 45° Stroke Angle: Instead of being to 30°, the better conveying angle of 45° can now be used when its wanted.
