Application ranges and use

Pneumatic conveying devices are very common in the bulk industry: They are easy to install, do not have many movable parts and require, therefore, only little maintenance and are very adaptable. Even in case of longer distances solid particles are blown by air or inert gas through corresponding pipings. There is a difference between pressure- and suction conveyance. Regarding the pneumatic conveyance the load of solid particles influences considerably the operation behaviour of the unit.

The smaller the load the less tendency for the pipings to get clogged. However, a smaller load (air conveyance / pressure conveyance) requires high flow speeds and a lot of energy leading to wear. In general hard and bulk materials sensitive to abrasion should be transported by means of suction conveyance, i.e. with smaller gas speeds. In the medium pressure range positive displacement blowers are proven for the pressure conveyance as well as for the intake operation. At present, Delta Blower Generation 5 is available for vacuum applications with nominal widths of DN 50 to DN 200. Further sizes are available in series Delta Blower.

Using a flexible modular construction and a belt driven system makes it possible for all blowers andmotor sizes to be installed, within a nominal range. Therefore, achieving an optimum adjustment tomatch the blower output and power consumption. Further modifications are also possible. For the new series Generation 5 10 vacuum series are available for intake volume flows from approx. 30 m³/h to 3.600 m³/h.

Examples of the various pneumatic application ranges are e.g.:

Cement technology
Foodstuff technology
Synthetic granulating pneumatics
Pharmaceutical industry
and many more
