Bulk Solids Handling & Processing Innovations
The Fröschl Beton company has been supplying construction sites in the Innsbruck area (Austria) with ready-mixed concrete for many years. Their 45-year-old mixing plant was technically obsolete and no longer met the standards of today. The wishes and requirements for the replacement purchase were high: Today and in the future, it was supposed to cover the entire concrete logistics chain and deliver flawless concrete efficiently and flexibly.
After an extensive planning phase,
Liebherr’s Betomat concept was chosen because it enables the operation of two
completely separate mixing plants within one mixing tower. The compact design
of the two weighing and mixing lines as well as the Liebherr quality and
service were compelling.
The Betomat holds up to 600 m³ of stone
in nine silo chambers. The mixing tower is fed with aggregates via two charging
hoppers and a powerful bucket elevator with an hourly output of 200 m³/h. The
plant has seven silos for a binder supply of around 840 tons.
The new mixing plant is equipped with two mixer systems: a ring-pan mixer with an agitator system and a double-shaft mixer. This means that normal standard concretes as well as high-performance and special concretes can be produced very efficiently. When in operation with both mixer systems, the plant achieves a possible output of around 160 m³ of compacted fresh concrete per hour. The tower is equipped with two lanes. Thanks to the separate weighing lines, two vehicles can be loaded simultaneously with different types of concrete – making the mixing plant highly efficient and flexible.
The environment and recycling also play an important role at Fröschl Beton. For environmentally-friendly operation, the housing and exhaust air filter systems reduce dust emissions. Noise emissions are also minimized. Residual concrete quantities from the truck mixer and plant cleaning, as well as re-concrete quantities, are processed in the LRS 908 residual concrete recycling plant. Washed-out material and residual water can be returned to concrete production. This enables considerable cost and material savings. The longevity of the plant is ensured not only by high-quality components but also by a precisely fitting steel construction from the Liebherr plant in Bad Schussenried. To ensure smooth operation even during the cold winter months, the entire plant is insulated with a 100 mm insulated wall and equipped with heating.
We as one of more than 130 companies of the worldwide operating Liebherr-Group, manufacture and offer beside our more well-known big products for the construction field also Moisture and Water Content Measurement Systems. In this field we are working hand in hand with local dealers in each country.
