Beumer bags building materials
B
uilding materials have their own specific characteristics,
such as high product temperatures or different volumes
and weights - they may show an unusual flow behaviour and
may be dimensionally unstable.
As a partner to this industry, Beumer Group says it can enable
material manufacturers to fill bags without any product loss with its
fillpacR filling machine. The series fills reliably, carefully and
sustainably while meeting the required throughput, says Beumer.
It is equipped with a weighing unit, which communicates
permanently with the filler neck via dedicated software. The
automatic bag weight control determines the exact filling weight.
This way the system always achieves accurate degrees of filling. Thus
the packaging line works more efficiently as it is no longer necessary
to remove under or overweight bags from the mat erial flow. In
addition, the quantity indicated on the bag always corresponds to
the real volume.
Air filling machines
Depending on the requirements and on the material characteristics
such as bulk density, flow behaviour or grain distribution, Beumer
offers both air and turbine filling machines from the construction
series. The air filling machines are suitable for bagging pourable and
coarse-grained products with particle sizes up to 10mm.
The systems use a blower to fluidise the materials in a pressure
chamber. The products can then be filled into bags gently and
precisely. Depending on the throughput, the user may opt for a
rotary or an inline filling machine.
The air rotary filling machines have four to twelve filling modules
which are arranged in a circular pattern. Depending on the number
of filling spouts, the systems reach a maximum capacity of 1,200 to
3,600 bags an hour for 25kg bags.
The air inline filling machines are generally equipped with one to
four filling modules. Depending on the number of filling spouts
positioned next to each other, the system achieves a capacity
reaching between 300 and 1,200 25kg bags an hour. Regardless of
whether the system is arranged in a circular pattern or in a line,
capacity and utilisation can be improved by installing an optional
automatic bag placer. The filling process is carried out either
automatically or at the push of a button. Two configurations are
available for removing the bag at the end of the filling process:
either manually or automatically with vertical bag discharge on a belt
conveyor.
system in a way that individual customer requirements or special
operational requests can be implemented flexibly and costeffectively.
Turbine filling
The turbine process is appropriate for companies which
predominantly fill free flowing and fine-grained materials, such as
cement or gypsum. The turbine filling machines use motor-driven
impellers. They can be arranged either horizontally or vertically,
ensuring a particularly high filling pressure and thus a very good
compaction of fine-grained materials to be bagged. The result is
filled bags which are compact and dimensionally stable so that the
user is no longer required to vent them.
With up to 20 filling modules, the Beumer fillpacR, for example,
can fill up to 300 tons of fine-grain materials an hour into diverse
bag types. The HDPE bag placer enables dependable filling of HDPE
bags. The filling impeller is characterised by its speed and the
maximum material throughput. The bag weight adjustment, which
automatically adjusts the weight of the next bag, always ensures
precise results.
Opening and closing of the vertically mounted filling spout is
carried out outside of the dirty area - this way the three-position
cylinder which regulates the coarse and fine flow is protected from
dust. The cylinder for bag discharging is also located in the dust-free
zone above the filling spout. This solution minimises wear and tear
on both cylinders and, therefore, ensures longer service life.
Beumer Group also offers the turbine filling machines with inline
design. The filling modules are placed next to each other for ready
access, which makes them easy to maintain. The inline filling
machines are best suited for production environments with low
throughput rates.
Individual customisation
The Beumer construction series is equipped with an ergonomic
control terminal. The improved human-machine Interface concept
allows operators to work in a simple and intuitive way. Almost all
built-in components of the fillpacR are freely available commercially.
This reduces delivery times for spare parts and lowers capital costs
for the user. Furthermore, the intralogistics supplier has designed the
Beumer has added the rotating filling machine, fillpacR, to its product portfolio and equipped it
with extensive features
