The manufacture
and processing of concrete, mortar and asphalt are among the core themes at the
international building trade fair bauma in Munich. To stay successful in tougher
economic times, the sector is looking in all areas for tailor-made,
cost-effective solutions. Here are some examples of the innovations visitors to
bauma in April can look forward to:
According to BHS-Sonthofen
GmbH competition is hotting up at present in the manufacture of ready-mixed
concrete. This German company has reacted to the increasing price pressure by
developing a new series of mixer models, DKXN. Thanks to a range of design
changes, the twin-shaft batch mixer is considerably less expensive than
previous model series. The DKXN mixers are designed primarily for the
manufacture of ready-mixed concrete in soft consistencies.
Elba-Werk
Maschinen-Gesellschaft mbH from
Ettlingen/Germany also manufactures machines for the production of
concrete.
One new product in its programme is the planetary counterflow mixer
EMPG 1000.
Planetary counterflow mixers are used mainly for block-making. This
mixer type distinguishes itself by a rotor which turns around the
vertical centre axis and, depending on the mixer size, is fitted with 1
to 3
rotating mixing stars or agitators. Due to the rotational axis of the
mixing
stars the individual mixing tools of the mixing stars form a sort of
planetary
path. The new gear of the ELBA planetary counterflow
mixer EMPG 1000 enables a variety of ratios to be set between rotor and
mixing
stars. That means that the energy input and/or the speed ratio may be
adjusted
to the respective mix. According to Elba, this
brings additional advantages in terms of product quality, wear and
energy
costs.
The new R16 intensive mixer from Maschinenfabrik Gustav Eirich (Hardheim/Germany) can
also adapt to any mixing task. The tool speed can be adjusted to between 2 m/s
to 40 m/s to suit the product in question. According to the company this helps
ensure high quality standards in concrete mixing even for large production
quantities and frequent recipe changes. The R16 copes with all materials of all
consistencies, from powdery and crumbly to liquid and pulpy, even viscous. The
usable volume of the new mixers is 600 or 900 litres, depending on the model.
All the machine modules are integrated beneath a travelling protective cover.
Knauf PFT (Iphofen/Germany) manufactures machine systems to
process grouts, plasters, mortars, screeds and paints. On the open-air site at
bauma the company is putting on a live simulation of a large-scale building
site. In around ten rooms and demonstration boxes, almost all applications for
the PFT machines will be demonstrated. One new product announced by the company
is a very high-performance one-man mixing pump, PFT Ritmo XL. This is available
in either a 400 volt, 3 phase version or a 230 volt, single phase version. The
continuous operation mixing pump is suitable for all pumpable premixed dry
mortars as well as for pasty materials – without any
modification. According to PFT it is easy to transport and very flexible thanks
to its dismountable modules.
At bauma 2010 the Swiss company Ammann is presenting its continuous asphalt mixing plant ContiMix,
which is now available in either a mobile or a stationary version. This forced
twin-paddle continuous mixer produces between 100 and 360 tonnes per hour.
According to Ammann emissions are lower because of the separation of material
heating and the mixing process. In addition, all the ingredients can be added
to the mixer simply, accurately and directly. The stationary model needs no
drag slat conveyor; housing is available as an optional extra.
Joseph Vögele AG of Mannheim/Germany is presenting its newly developed
tracked paver Super 3000-2 at bauma 2010. The machine has a basic width of 3 m.
Together with a new fixed-width screed, a laydown rate of up to
1,500 tonnes per hour is achievable and pave widths up to 16 m. This
configuration makes the machine suitable for large-scale construction projects
with jointless paving, for example the construction or rehabilitation of
motorways and airports. Customers who require greater flexibility can combine
the Super 3000-2 with an AB 600-2 extending screed. This screed handles a
maximum pave width of 9.5 m.
Dynapac of Wardenburg/Germany has developed the
Compactasphalt method in which two courses of asphalt are laid simultaneously
on roads or motorways in one pass, with both layers being laid hot on hot.
Until now Dynapac has offered one machine with a total width of 3 m, but now it
is bringing out a smaller CM2500 module with a total width of 2.55 m. In
contrast to the 3-m module, the drive unit is located on the front of the paver
where it takes on the function of a counterweight. At the same time it provides
more space for wearing material.
Zeppelin and
Caterpillar have also come up with a
compact design with the new asphalt paver AP555E Mobil-trac. By fitting the
engine in sideways, the designers have managed to reduce the length to 5.6 m.
This saves transport costs, because the paver can now be transported on a
single trailer together with other equipment, for example an asphalt roller.
Added to this are benefits in terms of manoeuvrability on the building site.
The machine can achieve a maximum working width of eight metres.
bauma in brief A
record 555,000 square metres and more of indoor and outdoor exhibition space
(gross) at the New Munich Trade Fair Centre are being dedicated to a display of
the latest products from the international construction, building-materials and
mining machinery sectors between 19 and 25 April 2010. Again over 3,000
exhibitors are expected to make use of this event, the world´s biggest trade
fair for the sector, as a platform for innovations and marketing. For further
