Pneumatic Conveyor
Purpose
- Move bulk materials that are suspended in a gas stream (most often air, but sometimes an inert gas) introduced by either a positive pressure blower upstream of material intake points, or by a vacuum pump downstream of material discharge points.
- Product is separated from the gas stream at the end of the line by filter receivers or cyclone separators or sent directly into process vessels.
- These systems can be integrated into process or production lines and will readily handle diverse products in the same equipment.
- Alternative to screw conveyors when the onsite installation is complex.
- Pneumatic conveying systems make it possible to transport powders over long distances, from 0.2 kg / h up to 1000 kg / h.
- A pneumatic conveyor system consists of the following system areas:
- Compressed air generation (the use of nitrogen or other gases is also common / possible)
- Infeed area (here the bulk material is fed into the pressurized conveying line via an infeed device)
- Conveying line system
- Receiving point
- The product is stored in a silo or big-bag then discharged and fed, using the bin activator and screw feeder, to a T-chute where it’s conveyed through a pipeline to its injection point.
