Device

Accuracy

Screw Feeder

• The volume of one complete flight of the auger

Rotary Feeder

• The volume of one complete pocket of the rotor

Belt Feeder

• Bed depth of material on the belt
• Diameter of the discharge rotor
• Belt speed

Vibratory Feeder

• The material delivered during dribble is not consistent due
  to bed depth of material and material characteristics
• The bed of the material must be deep in order to
  deliver fast/dribble feed

Rotary Scalpel™

• Large inlet opening fills rotary vanes uniformly
• Dribble feed is inherently most accurate due to the unique
  feature of delivering an adjustable finite volume of one vane
  of the rotating feed drum
• Not dependent upon angle of repose
• Ideal Flow Rate (IFR) since material inlet is configured to
  promote IFR in harmony with material flow characteristics
• Accuracies of < ±0.5 grams are achievable
