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 & Roller Vibrators - UCV & UCVR Series
- Rotary vibration
- Nominal frequency 6750 min -1 to 19900 min -1 (ball) - 9800 min -1 to 12300 min -1 (roller)
- Force output 110 N to 34345 N (ball) - 490 N to 14130 N (roller)
- Cast iron body
- Frequency and force adjustable by air pressure
UCV / UCVR vibrators are used for moving material from hoppers. The rotary action is ideal for moving product down chutes. The cast iron body makes them suitable for underground use.
Precision machined ball / roller is driven around a hardened race by air pressure. Adjusting the pressure changes the frequency and force output.
Operating Conditions Drive medium:
Compressed air with filter and with lubrication
200kPa to 600kPa
-20 to 150°C
-20 to 180°C with air bleed
