Weighing & Dosing

Loss In Weigh Feeders

Totally enclosed gravimetric feeding device for powdery or small granular bulk solid materials and liquids. Products family ranging from a few kg/h to 30 t/h.

RBP

The feeders work using the principle of controlled Loss-In-Weight. The hopper with its extraction device (screw) is installed on a weighing system giving continuously to the controller the measure of weight.

The loss of weight by time unit ( measuring sampling time) represents the actual proportioning flow rate.

 

  • Accuracy ± 0.5 %
  • Flow range from 12 l/h to 14 m3/h
  • Accuracy consistency
  • Entirely tight system, no environmental impact
  • Low maintenance
  • No need fro drop tests
  • Few wear parts
  • Manual or automatic refill
  • Horizontal stirrer in lower part that ensures material homogeneity (Option: Vertical stirrer for poor flowing products)
  • Bearing at screw outlet for a better centring in the tube (less cantilever)
  • Enforced tightness by glands, chicanes and 4 Teflon braids
  • Inspection door in lower part for eventual replacement of horizontal stirrer without dismantling the whole feeder.
  • Execution: Steel S235-JRG2, stainless steel 304 and 316
