Pressure System
  • For high unloading rate
  • Utilizes under-track hopper to dump entire car, then pressure tanks or feeder/airlocks for line charging
  • Can be designed with dust capture system at hopper
Vacuum System
  • Relatively low rate (10 to 20 STPH)
  • Utilizes hopper pan: either multiple hook-up or manually moved from hopper to hopper
  • Maximum practical hose connection is 8"
  • No need for pit under railcar
Vacuum / Pressure System
  • Increased convey rate compared to vacuum only (20 to 30 STPH)
  • Pressure side either feeder or tank based
