Material flow inside the mixer is
a big deal. Proper blending
requires that there be no dead
spots or paths of recirculating or
non-mixing feed. While most
mixers are designed with this in
mind, some do not have
sufficient material flow to
adequately blend liquids which
are added rapidly to the mixer.
Some mixers do not have good
material flow when the batch
size is a small fraction of the
mixer capacity. Many observers
of TMR systems agree that one
of the most common errors
made in putting together a TMR
delivery system is simply the
mixer capacity. It is important to
have a proper capacity for
several reasons:
Allow for adequate blending without excessive mixing time
(and perhaps excessive particle size reduction)
Assure adequate blending of the ration
Optimize labor use for feeding
Optimize equipment cost
