Suction Pneumatics

This process of filling molten products into the respective containers is important at Ebbecke Verfahrenstechnik AG after successful pastillation. The suction blower station generates a vacuum in the balance. By opening the shut-off device, the conveyed material is sucked through the suction conveying line into the receiving station.
Pros and cons of pneumatics
Pros
- Pneumatic drives allow powerless holding with constant force.
- Pneumatic systems are robust against overload and insensitive to temperature fluctuations.
- In most cases, the use of air as the drive medium ensures sufficient cooling of the drive components. Additional cooling is not necessary in pneumatic applications.
- Pneumatic drives have a relatively simple design and are therefore less expensive than electric drives with comparable performance data.
Cons
- Escaping compressed air causes noise. As a countermeasure, the exhaust air can be discharged in a captured form or released into the ambient air via a silencer.
- Depending on the application, complex air treatment is necessary in some places, e.g. to ensure that the compressed air is oil-free, to limit the particle size to a minimum or to reduce the dew point (otherwise there is a risk of water formation and the formation of ice).
