In the former model a ball is rotated by air pressure around the inside of a hardened steel race to give an out of balance force. The speed of rotation and the force output are varied by changing the inlet air pressure. This principle also applies to the roller type. In the turbine, an out-of-balance turbine is held in bearings while being rotated. In this case there is no metal to metal contact which gives a much quieter operation with no lubrication required.

Again, varying the air inlet pressure will change the frequency and force.

Pneumatic Ball Vibrators - NCB Series

• Rotary vibration
• Nominal frequency from 7,220 min-1 to 42,340 min-1
• Centrifugal force from 220 N to 4,866 N
• Frequency continuously adjustable via air pressure
• Suitable for temperatures up to 200ºC (HT Models)

Applications
Series NCB pneumatic ball vibrators can be used wherever bulk materials need to be moved. They serve in the emptying of bunkers, for preventing bridging, rat-holing and adhesion. When used to drive chutes, sieves and vibrating tables, they ensure that the material flow is maintained. The special feature is the simple construction.

Construction and Working Principle
The rotary vibration is created by the high centrifugal force produced by a circulating steel ball, which runs on hardened, polished steel races. The frequency, and hence the centrifugal force, can be continuously regulated via the operating pressure. Series NCB ball vibrators can be operated using lubrication-free compressed air.

A multi-directional valve is required for operation (not included in the scope of supply).

Permissible Operating Conditions Drive medium:
Compressed air or nitrogen (filter ≤ 5 μm), preferably with oil mist

Operating pressure:
200 kPa to 600 kPa

Ambient temperature:
– 20ºC to +120ºC
HT version up to +200ºC
