Pneumatic Vibrators

External Pneumatic Air Vibrators combine high frequencies with high centrifugal forces. Vibrators are operated with filtered compressed air. They require minimal maintenance and they are successfully used as flow aids on bins, as drives for chutes or screens, and on vibrating tables.

Working principle: Vibration is generated due to an unbalanced turbine. When air flows it exerts a force on the blades of the turbine. Depending on the mass of the turbine it rotates as a certain speed. The turbine is made unbalanced due to which on every rotation of the turbine, a vibration is produced. The vibration frequency of the pneumatic turbine vibrator could be regulated by varying the air pressure.

Pneumatic vibrator motors are par­ticularly suitable for conveying, compacting and detach­ing of bulk solids due to perfectly linear vibrations. They reach optimum results in emptying of bins or as drives for vibrating conveyors or feeders.

Working principle:

 

Applications:

1. Compaction of ramming mass for induction furnace lining

2. For Concrete Compaction

3. Used as car shakers to dislodge materials from goods wagons / rail cars

4. Used for dislodging of materials from huge hoppers or silos

5. Loosening of core sand from castings

6. Vibrating tables

Material of Construction:

1. S.G.Iron Body

2. Moving Parts - Shock Resisting Steels

 

 

External Piston type Vibrators as the name suggest uses a piston to produce vibrations of a certain amplitude. These are par­ticularly suitable for conveying, compacting and detach­ing of bulk solids due to perfectly linear vibrations. They reach optimum results in emptying of bins or as drives for vibrating conveyors or feeders.

Working principle: Pneumatic Piston Air Vibrators are essentially piston oscillators. The piston is made to oscillate to and fro by a positive feedback signal. The oscillations are generated by impact vibrations. The oscillations of the piston are cushioned at one end and free at the other, malleting continuously. The high frequency of the malleting motion produces vibrations. 
Piston Air vibrators have been developed for applications requiring "Linear pulsating Force".
They can be used for promoting material flow from small hoppers, down feed pipes and chutes and as prime over for screen, Feeders, compaction and testing table etc.

These Pneumatic Air Vibrators have been designed for application that require small to medium amount of vibratoins in laboratory equipment, small hoppers, component feeders, powder filling equipment etc. The exhaust can be piped away if required.

Salient Features of these Air Pneumatic Vibrators:

1. Simple Construction

2. Muffled Exhaust

3. Low Weight

4. Variable Frequency

5. Dual mount Provision

6. Easy to maintain

7. Completely Enclosed

8. Needs no Lubrication

Applications of these Air Pneumatic Vibrators:

1. Powder filling Machines

2. Food Industry

3. Pharmaceutical Industry

4. Packing lines sieving

5. Vibration Tables 

These Pneumatic air vibrators work on a turbine principle and are silent than ball or roller vibrators. These air turbine vibrators are low on maintenance much more efficient and low on air consumption than equivalent models working on ball or roller princinple
