Venting Options
Lightweight, fluffy materials, those
that are extremely dense or flow poorly
can be difficult to handle in bucket
elevators at high speeds. Because these
materials tend to trap air when being
handled by an elevator bucket, it is
necessary to provide air relief to
assist in their filling and discharge.
Materials in this category might be
various flours, meals, feed mash or
screenings. As these materials enter the
bucket, air is released through a series
of vent holes in the bottom of the
bucket allowing for a more complete
fill. These vent holes also allow air to
re-enter the bucket, which facilitates
full release of product into the
discharge.
Generally hole diameter is equal to bolt
holes drilled for attachment. In certain
cases, larger diameter holes may be
necessary.
When elevating powdery materials such as
cement in the Tiger-Tuff, a minimum of
two rows of 3/8" diameter vent holes are
recommended to help insure that the
material will discharge cleanly.
