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
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)
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
Food Grade Quality	Available	Available
Maintenance	Negligible	Negligible
