WHERE CAN VIBCO VIBRATORS BE USED?
Settling products into containers, bags, bins, and bottles. Also compacting of concrete in forms or moulds.
Freeing up materials to remove the contents of containers, bags, bins or hoppers, tip trucks, and bottles. Also helping concrete to run down a chute. (All very similar to the above).
Feeding of bulk material from bins or hoppers, at a controller rate and being able to stop and start it feeding as required.
Conveying of product in a clean tray, and be able to distribute it via gates or chutes onto different conveyors as may be required by a process system.
Elevating, by the clever application of vibration around an axis, product can be conveyed up and around a vertical spiral.
Applying the same axial vibration to a bowl with an internal spiral the orientating of components into a particular attitude for further processing. Caps for fitting onto bottles, small parts into assembly, or corncobs to cutters are some examples.
Aligning flat sheets Products such as paper can be aligned using vibration (cheques or vouchers for processing, paper prior to printing).
Screen to sort a bulk material into different size range, also separation of different products can be achieved.
Polishing, burnishing, de-flashing of components by rumbling in a trough or tub, also grinding is possible.
Stress relieving of castings or fabrications by applying a range of different frequencies over time to the product.
Testing of packed products or electrical components for suitability in the field.
There are a few practical limits in the applying vibration to a mechanical system, but as with most things it can be an expensive if incorrectly applied. The application need not be expensive, and can provide a unique solution to a flow problem with the application of a simple vibrator. Even complex bulk materials handing systems can be engineered to use vibration as the driving force in processing and handling of a large range of products.
As there are many yet undiscovered applications to solve difficult problems, engineers need to be innovative to examine all the possibilities.
A company wanted to separate the round pieces of glass from the angular pieces, all having a similar size. By setting up a feeder to with the pan slightly uphill and then slowly feed the mixture onto the pan, it was found that the angular pieces feed up the pan, and the round pieces rolled down.
In Europe a vibrator was attached to the plate under a counting system for day old chicks, the vibrating plate caused the chicks to hesitate, giving better separation for a more accurate count.
We understand that a new alarm clock will utilize vibration to shake the sleeper awake.
And some cleaver guys in a Canberra University are looking at generating sufficient electricity, from the ambient vibration of a machine, to power remote sensors. Thus eliminating the often complex wiring required to power sensors.
What are the different types of vibratory action?
Rotary Vibration
A circular motion, which is generated by electric vibratory motors, air turbines, ball vibrators, and eccentric or out of balance shafts.
This is simply shaking an object, devise or machine to obtain product movement, whilst force and frequency can be controlled the actual vibrating action is subject to variation caused by the structure of the object. It is used for:
- Screening
- Grinding, Polishing & Mixing
- Shaking of hoppers & Chutes
- Packing & Settling Tables
- Consolidation of products
- Testing
Linear Vibration
Achieved by using two contra rotating rotary vibrators, crank arm, piston vibrators, or Electro magnetic drives. By applying an even straight-line vibration at a selected angle a product can be thrown up and travel forward as the pan moves back. Uses:
- Feeding
- Screening
- Conveying
- Grading, Inspection & Sorting
- Shaking of hoppers & Chutes
- Packing & Settling
- Testing
Combination / Special
By vibrating a specially designed system an action can be achieved such as a linear stroke around an axis or modifying a Rotary or Linear vibration to become elliptical. Various changes can be applied to achieve a special action to make a product move in a particular way to achieve a desired result such as to get the product to travel up a spiral track, or increase the time the product stays on a screen. Applications:
- Screening – (Gyratory Screens)
- Elevating – (Spiral Elevators)
- Feeding and Orientating – (Parts Feeders)
- Hopper Discharges – (Bin Dis-charger)
- Special applications – (turn tables and special consolidation units)
