The process
Packing plants raise cement dust at the packer spouts, bag loading and truck loading points. Dust extraction fans pull the air into bag filters, and air slide blowers feed the packers from the silos.
The gas
Ambient air carrying light dust from the surroundings, enough to settle on blades over months but not to erode them. Inlet screens and a wheel that sheds deposit are the usual precautions.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| Air Slide Blower | Supplies low pressure aeration air to the fabric of an air slide, fluidising cement, raw meal or gypsum so it flows down the slide.. | Backward curved and radial tipped |
| Ventilation Fan | Moves air through a plant or building for fresh air supply, heat removal and fume dilution where the system is ducted. | Backward inclined and forward curved |
