How to Set Proper Bowl Speed
Ask your direct supplier for the actual linear feet per minute at
which the bowl should rotate. For reliability, set the bowl to match
that speed.
▲
To set bowl speed, you will need a hand-held tachometer (analog
or digital) with a surface speed wheel indicator (see Figure 5-1).
▲
This procedure is performed with the power on and the feeder
operating. If your direct supplier has installed a cover over the
bowl, you will need to open it before proceeding.
Step 1ÑTurn on Feeder.
Turn on the feeder and run it without
product.
Step 2ÑSet Bowl Speed.
To set the bowl speed, place the hand-
held tachometer (with surface speed indicator attachment) on the
inner wall of the moving bowl, at its most upper inside diameter.
Adjust the bowl speed until the bowl is moving at correct number
of linear feet per minute (FPM).
Step 3ÑRecord New Settings.
Turn off the feeder. Mark dial plate
with new setting and remove any old marks.
