When the requirement arises for very high speed orientation and feeding of parts, then the only alternative is to go for a Rotary or Centrifugal Feeder. These can help achieve speeds of upto 50 meters per minute. Secondly, there being no vibrations and only mechanical items, rotary feeders are more acceptable to a lot of customers who are afraid of the reliability of vibratory bowl feeders in the long run (however, using a vibratory bowl feeder from a reliable supplier like Elscint can reduce this inhibition).

Models Available

  • Model 40
  • Model 60
  • Model 80
  • Model 100

A comparison chart mentioning the advantages & disadvantages of Rotary or Centrifugal Feeders vis a vis Vibratory Bowl Feeders are given below –

Vibratory bowl feeder Rotary / Centrifugal Feeder
Maximum speed 12 to 15 meters / minute 50 meters / minute
Usage of Air Jets Maybe required for high speed / critical orientation Mostly required for easy flow & orientation
Variety of parts which can be oriented & fed Almost all parts Only certain parts can be fed & oriented (eg. bottle caps, cylindrical rollers, needle rollers, flat and cylindrical drippers, bearing races, bearing rings etc)
Electrical supply 1 Phase 3 Phase
Possibility of damage to parts Negligible Sometimes possible for brittle parts
Loading quantity High (depending upon model) Less (Stock feeder / Hopper Elevator always required.
Variety of components Possible with changeover tooling Possible with changeover tooling
