K BALL VIBRATORS

This is the simplest version of all vibrators and has been used for half a century. A steel ball driven by air rotates on hardened steel races and creates unbalance and vibration in a sinusoidal energy wave.

Manufactured with a rustproof extruded aluminum body fitted with hardened steel races on which a steel ball rotates.

Nylon endplates are located on either side to contain the ball and prevent the entry of dust and water, thus allowing the unit to be used in dusty or wet environments.
Inlet and exhaust port have standard pipe threads, allowing
the exhaust air to be piped away, ensuring that no restriction is imposed on exhaust air.

Four mounting holes are provided, two vertically and two
horizontally for handling difficult mounting positions.

HOW IT WORKS

Series K, which is small in overall size, pneumatic ball vibrators frequency can be regulated by adjusting the flow of air to the vibrator making them useful for:

  • Assisting the flow of material from chutes and hoppers.
  • Preventing bottles and similar objects from locking together and blocking conveyor systems.
  • Compaction of material in containers or molds.
  • Separation of various sizes of material on screens Packing machinery.

TECHNICAL DATA
Unbalance Weight: Ball (Type number is diameter in mm)
Lubrication : Not necessary
Air Supply : 30 to 90 PSI
Air Type : Clean, use of filter (40 µm) recommended
Body : Aluminum, stove-enamelled cream-grey
End Caps : black Nylon, self retaining
Max Temperature : 220°F (100°C)

ADDITIONAL TECHNICAL INFORMATION

  • Air pressure inlet and exhaust ports have standard pipe threads, allowing the exhaust air to be piped away, ensuring that no restriction is imposed on exhaust air.
  • The pipe thread is BSP (British Standard Pipe) but will accept the US NPT (National Pipe Thread).
  • The K indicates the ball series and the number stands for the diameter of the ball in millimeters.
  • The maximum ambient operating temperature is 100°C (220°F).
  • The noise level range is 75 to 95 dBA with muffler.
  • Epoxy paint coating

Installation / Operation

You can place the vibrator in any mounting position. The centrifugal force created when the air pressure is applied will cause the ball toimmediately find its correct path on the race.

NOTE: If the vibrator is mounted with its rotary axle in a vertical position, the lower end cap will hold the ball as long as no air pressure is applied.
As soon as air pressure is applied the ball will rotate on its races and not move along the end plate any more.

The ball vibrators can be operated intermittently without losing their effectiveness or causing other difficulties since the vibration stops immediately after pressure is cut. Therefore, it is very useful in packing machinery industries.

Lubrication is not required, but only clean (filtered) air should be used because dirt will cause the ball to jump and dent the ball's race.
