Gentle dilute-phase conveying of plastic
pellets
Coperion GmbH, Weingarten/Germany, will be
presenting its latest developments for gentle
material conveying at its booth B19, Hall 14
at the K 2016. For the first time Coperion will
be presenting the newly developed deflector
elbow GAMMA-BEND NT, which prevents the
formation of angel hair.
wall, thus preventing the development of angel
hair. Due to the deflector elbow’s special design as
a segmental bend, the pellet grains hit the elbow
wall, ricochet , and are further conveyed directly in
the bend. Minimal contact with the elbow wall also
reduces the formation of dust significantly.
The GAMMA-BEND NT can be used universally
in conveying systems, as there is no buildup of
product cushions and thus always consistently
empties with no residue. This is of vital importance,
particularly for product changes.
In addition, Coperion will be showcasing its reengineered and optimized ZV rotary valve for
pellets. Further developments have allowed the
throughput to be increased and noise emission
significantly reduced. In addition, improvements
to the rotary valve’s housing have substantially
lowered the gas leakage rate.
For the operation of a pneumatic conveying system
it is important that the pressure drop at bends
should be as low as possible. This is particularly
important if several bends are used in a conveying
system. In comparison to all other special deflector
elbows in the market, the GAMMA-BEND NT has
proven the lowest pressure drop, meaning that this
bend is particularly energy efficient.
GAMMA-BEND NT deflector elbow for the
prevention of angel hair
At K 2016 Coperion will be presenting for the first
time its newly developed deflector elbow GAMMABEND NT for dilute-phase conveying of pellets. The
deflector elbow effectively prevents the formation
of angel hair, which would otherwise be generated
particularly in critical, right-angled direction
changes. The special geometric design of the bend
keeps the pellets from sliding against the exterior
