Global Manufacturing DS-41 Pneumatic Ball Vibrator

Ball vibrators use compressed air to push a steel ball around a raceway to produce rotary vibration. The heavier the ball and the faster it moves the greater the centrifugal force produced. Ball vibrators are the simplest and least expensive rotary vibrators.

When harnessed by proper mounting of the ball vibrator, the rotary vibration is transferred through the hopper wall to the material within. As the material vibrates, its displacement from the hopper wall reduces friction with the wall and allows gravity to restore material flow. Proper mounting also disperses the rotary vibration over a large area producing uniform material flow. Since rotary vibration is directional, material will be encouraged to flow in the direction of the rotating ball.

Applications:

• Ball vibrators operate at relatively high RPM producing high frequency vibration. This makes them well suited for moving fine materials such as dry sand, flour, sugar, cement, spices, powders, dust, and so on.
• When the frequency of the vibration matches the natural frequency of the material, enhanced flow can be achieved with a minimum of force.
• It is easy to tune a ball vibrator to the material being handled. Simply increase the speed by gradually increasing the airflow to the vibrator until material flow is achieved. This way you obtain the maximum result with the minimum of air consumption and vibrator wear. Once the material moves freely, the vibrator can be turned off until it is needed again.
