| Since
the setting up in 1994, BKG has been
offering - together with our partners of the Kreyenborg
group who have completed 50 years in the industry- comprehensive
conceptions for underwater pelletizing. This special
procedure is currently the most promising, innovative
and, concerning the range of plastics materials to be
processed, the most flexible technique for the production
of high-quality plastics pellets. The company which
belongs to the Kreyenborg group is one of the leading
suppliers of Underwater Pelletizing Systems world-wide,
which is the innovative technology facilitating the
production of high-quality plastics pellets.

Melt Filters / Screen Changers
When extruding plastics, a contamination-free plastic
melt is desired. Since contamination affects the quality
of the product and impedes the operating process,
it is essential to ensure a perfect filtration process
and improve the quality of the plastic melt by using
a melt filter.
For more than 30 years KREYENBORG have been active
in the construction and design of melt filters, called
"Screen Changers".
Applications:
KREYENBORG Screen Changers are used for the filtration
of
· all kinds of thermoplastics
· foamed plastic materials
· even under the hardest operating conditions
· others on request
Our Screen Changers are used for the production
of
· flat, blown or cast films,
· fibres, tapes and sheets,
· pellets,in the field of recycling,
· as well as in the fields of injection and
blow molding processes.
Characteristics:
· easy handling
· extremely easy maintenance
· robust and wear-resistant construction
· precise machining
· leak-proof design
· low screen and energy requirements
KREYENBORG Special Silos
Light-weight bulk material such as film flakes, fibers,
hollow part ground stock, non-woven flakes, foams
etc. quickly tend to bridge during the discharge.
Therefore the KREYENBORG Special Silos are an important
component of a lot of plastics recycling lines following
the size reduction for the intermediate storage and
for the dosed input into the following extrusion,
agglomeration, etc.
Special Fiber Silos (one agitator)
This silo is primarily designed to store extremely
light and quickly bridging fibers. In this case the
bulk density may show a value of far below 0,1 kg/dm³.
Special Film Flake Silo (three agitators)
Materials
with bulk densities of approx. 0,3 kg/dm³ are
stored in these silos – on request also homogenized
– and discharged by means of an adjustable discharge
screw.
Special Block-Type Silo (angular structural
shape)
For the storage and the dosed discharge of film flakes,
fibers, foams etc. KREYENBORG offers the special block-type
silo. With this type of silo there are nearly no limits
concerning the bulk density, the strength or the consistence
of the material. A further advantage of these silos
is the space-saving structural shape as well as the
great storage volume with small overall height. The
modular design enables an economical transport of
the big silos and also a loading into oversea containers.
