The process
Dilute phase conveying of powders and granules needs a blower at the line pressure and a bag filter at the receiving end. The blower handles clean air at high pressure; the filter fan handles the conveying air with residual fines.
The gas
Extraction air from crushers, screens and transfer points, carrying abrasive mineral dust. Radial wheels with wear protection ahead of the collector, or efficient wheels behind it.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| High Pressure Blower | Delivers combustion, aeration and conveying air where the system resistance runs to several thousand millimetres of water column in a single stage.. | 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 |
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
