Flexible Screw Conveyors

FlexMAX® Flexible Screw Conveyor Inlet Hopper


The inlet feed hoppers for our FlexMAX® flexible screw conveyors come in three standard sizes. Our inlet feed hoppers include a number of key features that improve flow and reduce bridging in the hopper. The main advantage of our inlet feed hopper design is that it incorporates true 60-degree side walls. This is the ideal angle for flow out of a square hopper. The second major advantage is our rounded FASTFLO Corners. By using a large radius bend in the corner of our inlet feed hoppers, we reduce the potential for the product to set up in the sharp corners of a traditional hopper.


Inlet feed hopper features:

  • 4, 8 and 12 Cubic Foot Hoppers standard
  • True 60 degree sloped sides and rounded corners
  • Large 10” diameter inlet and 3” NPT standard dust port connection
  • Safety grate
  • Quick opening latches for hopper lid
  • Removable bottom cap for easy clean out
  • Optional Pneumatic Feed Hopper Vibrator
  • Optional Electric Feed Hopper Vibrator
  • Optional paddle level sensors
  • Optional pneumatic aeration pads
  • Optional lid safety switch
  • Optional Bag Break lid
  • Optional padd-style agitator assembly
