How to tune a vibratory bowl feeder

1. Check the air gap between the coil and the "I" lamination assembly.  It must be clear of debris and not striking one another. The gap in between the "I" lamination and coil should be as such that they do not strike one another on startup, the coil getting as close to the "I" lamination assembly as possible.

2. While the bowl is running with parts in it, loosen a spring bolt. If the unit speeds up, it is over sprung.  Remove a spring, tighten the bolts and recheck. If the unit slows down, it is under sprung. Add a spring, tighten the bolts and recheck.

3. Recheck and adjust the air gap as close as possible without causing the coil and "I" lamination assembly to strike on startup.

4. Always be aware of bolt length and maintain proper thread engagement when adding or removing drive spring.

5. When possible, maintain a balance on all the spring packs. Do not remove several springs from one pack and leave an unbalanced condition.

Reminder:

1. Vibratory equipment must not touch any track, bracket, or other equipment.

2. Never attach anything to the bowl or base drive.

3. Operate the system at the minimum speed required to obtain good parts travel and meet the specific rate.
