The Problem...
To Shred and Bale Returned Magazines
and Paperback Books
Eleven years ago,
Southeast Periodicals and Book Sales, Inc., Miami, FL, installed a
BloApCo 3CAX/S-3058-BVA shredder over a horizontal baler to shred and
bale returned magazines and paperback books. Some of their magazines
were 8 1/2x11" and over 1" thick. At that time, Southeast Periodicals
anticipated that volume would grow to 50 tons per week. Their current
volume was up to 100 tons per week. They
found that when they were feeding at maximum volume, some magazines
were not being thoroughly shredded. Not only was the shredder having trouble
keeping up, the bale quality was poor. In addition, they also needed to
shred corrugated and newspapers, which require a slightly different shredder
than one for books and magazines.
The Solution...
BloApCo's 50-N Narrow Extra Heavy Duty Material Handling
Fans
Two approaches
were considered: (1) Upgrading or replacing their shredder so that everything
can be handled by one shredder, or, (2) make minor modifications to
the shredder to allow it to shred newspapers and corrugated boxes and
install a separate magazine destruction system utilizing an extra heavy
duty BloApCo material handling fan. The latter was chosen.
A BloApCo
50-N narrow extra heavy duty material handling fan with 60-HP motor,
destroys books, newspapers and magazines -- even thick phone books.
This fan, which is heavier than any previous BloApCo material handling
fan, was developed over the past 25 years specifically for tearing apart
paper products. A special receiving hopper was designed to allow the
books and magazines to drop from the 48" wide feed conveyor into an
air stream feeding the 50-N fan. The books literally disintegrate upon
impact with the fan blades, thus ensuring total book destruction.
Once
the books have been torn apart, they are conveyed by the action of this
same fan, pneumatically, to a cyclone mounted over a baler. Shredded
paper is separated from the conveying air within the cyclone and deposited
into an auto tie baler. The conveying air discharged from the cyclone
is fed into a series of filter bags to remove any dust, thereby allowing
the conditioned air to be returned to the building. A floor sweep was also
added to enable the operators to easily keep the scrap room clean.
The material
handling fan, cyclone, filter bags and auto tie baler were installed
while the existing shredder remained in operation...ensuring no loss
of production. The resultant destruction of magazines and books is excellent,
actually better than that provided by the shredder, and bale quality
also is excellent. Bales weigh 1,600 pounds. Most importantly, Southeast
Periodicals can now process more than 5 tons per hour of books and magazines,
nearly twice their current volume requirements.
