The quality of raw
materials plays a decisive factor in being able to achieve a homogenous mix of
high-quality concrete inside the mixers. Both the raw materials and mixers
significantly influence the appearance and performance of the finished concrete
products. The production of main mix and face mix concrete have different
criteria meaning the respective mixers require specific solution-based
approaches. While in main mix concrete production, the primary requirement is
to achieve the highest possible quantity of concrete while maintaining the
quality, the focus in face mix concrete production is on achieving the highest
possible quality while limiting the quantity to small batches. In addition to
the pure performance of a mixer, plant operators value its serviceability and
ease of maintenance. In 2022, Masa exhibited the PH 2000/3000 mixer optimized
for main mix concrete production and the special S 350/500 face mix mixer at
bauma in Munich. For both models, Masa engineers had developed new,
service-oriented features.
Masa has been
differentiating between different mixer concepts for main mix and face mix
concrete for many years. The mixers of the PH class have been an integral part
of the Masa mixer portfolio for decades. The Masa S 350/500 for face mix
concrete was first built in 2008 and made its first public appearance at the
NCMA Icon Expo in Indianapolis, USA in 2013. The high-tech mixer, then called Twister,
was a real crowd puller at the Masa booth in Indianapolis as well as at bauma
2013. Stagnation is regression, which is why the mixer specialists at Masa do
not lose sight of continuing to optimize our products. Both small, detailed
modifications and larger improvements contributed to the overall changes that
are impressive and were most recently presented in Munich at bauma 2022.
PH
2000/3000: Reliable supplier of large main mix concrete quantities
One noticeable feature of
the Masa PH mixers that stands out at first glance is the massive and solid
construction, which is reflected in its overall weight. For example, the
largest Masa PH 3000/4500 mixer weighs significantly more than many of its
competitors. Even the PH 2000/3000, which is almost 18 t, cannot be considered
lightweight. The significant increase in the amount of steel used is
noticeable: The overall design has a very high flexural rigidity, and the
mixing trough is very dimensionally stable. As a result, the side scrapers, for
example, continuously deliver reliable work results. In addition, the extra
steel also increases the durability of the mixer.
The PH 2000/3000 main mix
mixer with a powerful planetary gearbox and two external 45 kW drive motors of
energy efficiency class IE3 can achieve a maximum output of 2,250 l per mixing
cycle. Overall, it is characterized by short mixing cycles, low wear, and very
high plant uptime.
Masa
mixer portfolio for different requirements
Mixing on the PH
2000/3000 is performed by three robust mixing stars arranged in different
positions. Each mixing star has three streamlined mixing arms, with one mixing
arm installed offset in height. This arrangement takes into account the
respective filling level of the material to be mixed and has a particularly
positive effect on the homogeneity of the mixed concrete. The entire batch is
captured and mixed uniformly and continuously.
