Rail Car Unloading: Gravity / Pressure Systems
- Best for high rate unloading
- Suitable for coarse product (pebble lime)
- Utilizes undertrack hopper to dump entire car, then pressure tanks or feeder/airlocks for line charging
- Can be designed with dust capture system at hopper
Typical installation at Sunflower Electric
Rail Car Unloading: All Vacuum Systems
- Relatively low unloading rate if to top of silo (10 to 20 STPH max)
- Suitable for all standard bulk products
- Utilizes hopper pan: either multiple hook-up or manually moved from hopper to hopper
- 8" is max practical hose connection
- No need for pit under railcar
Rail Car Unloading: Vacuum Pressure Systems
- Increased convey rate compared to all vacuum (20 to 30 SPTH max)
- Suitable for all standard bulk products
- Utilizes hopper pan: either multiple hook-up or manually moved from hopper to hopper
- Pressure side either feeder or tank driven
Typical installation at AB Brown Station
