What determines pellet mill
The capacity of a

various factors including:

Plants normally operate in cycles by
blending and mixing consecutive
batches of one or two tons each. The
required output is then accomplished
by designing the unit to produce a
certain quantity of batches per
hour. The quantity of batches and
raw ingredients will determine the
sophistication and design of the

elements in the feed mill are well
balanced to produce the required
amount of batches without blockages
Raw and finished products can be
handled in bulk but bagging is
required where the end user cannot
handle bulk feeds.
