Mobilmix 2.5 offers even higher performance and greater efficiency than its predecessor.
Concrete mixing plants are becoming more flexible and innovative to ensure they meet increasingly stringent construction schedules.
Increasing demands are put on contractors to cut down the transportation of material to construction sites in the name of efficiency and the environment. For that reason concrete mixing plants are increasingly flexible in their transportation to sites, their set up times and their output.
Ammann Elba, the company created when German-based Elba was acquired by6791 Ammann in 2014, has introduced the new CBS Elba Concrete Mixing Plant. It is designed for small and medium-sized businesses seeking flexible concrete plant solutions. It features state-of-the-art design and offers output ranges from 105m³/hr to 160m³/hr.
The basic unit can accommodate both EMS and EMDW single-shaft and twin-shaft mixers with a hardened concrete output volume ranging from 2m³ to 3.5m³. The CBS Elba offers easy, low-cost transportation for stationary and semi-mobile operation.
A new line of mobile and compact concrete-mixing plants also has been launched. The first plant in the product family, the CBT 60 Elba Compact Concrete Mixing Plant, has an hourly output rate of 58m³/hr.
The CBT 60 Elba is equipped with an Elba EMS 1000 single-shaft mixer and an integrated linear batcher for storing between two and four aggregate components. Fast installation times and trouble-free relocation result from the elaborate folding mechanisms. No foundation is required for plant installation.
The entire compact line-up, available in the near future, will provide a performance range from 30m³/hr to 130m³/hr.
The CBS Elba Concrete Mixing Plant rounds out the Ammann concrete plant range that includes the ELBA Supermobil - ESM 30 C – with a concrete output of 30m3/hr, compacted fresh concrete
Ammann says the ESM 30 C fitted with an ELBA EMS 500 single-shaft compulsory mixer is the most compact mixing plant of the mobile ELBA machine series.
The ESM 30 C has been designed to suit container dimensions – the 40-foot or 12m sea container with CSC approval - and reduces transport costs to a minimum. For transport, the integrated mixing and weighing systems remain in their operational positions. The preinstalled electrical and pneumatic equipment is mounted safely.
Pluggable connections allow the included operator’s cabin to be installed flexibly. The concrete is discharged via a concrete discharging belt that can optionally be installed on three sides. The compact design allows you to use the mixing plant in new fields of application and for new operations.
Within the same family is the ELBA Supermobil - ESM 60 with a concreting output up to 60m3/hr, compacted fresh concrete. A diversity of installation options, without foundation or on a concrete plate, ensures optimum mobility. The machine fitted with an ELBA EMS 1000 single-shaft compulsory mixer is capable of achieving hourly outputs of up to 60m3.
All-around accessibility of the ESM 60 facilitates regular maintenance or service works.
Pluggable connections enable the plant to be erected quickly. For the aggregate storage, there are in-line bins of different sizes and volumes.
From718 Liebherr comes a new concrete mixing plant, the Mobilmix 2.5 that offers especially flexible operation, according to the manufacturer. It is easy to transport and can be set up within two days, an important feature for ensuring efficient on-site schedules Because of this it is ideal for operating at sites with limited concrete production times or other challenging projects.
Equipped with a state of the art twin shaft mixer, its performance and comfort is comparable to a stationary mixing plant. Compared to its predecessor version the Mobilmix 2.25, the output capacity has been increased by 10m³ to 110m³ per hour.
Customers can expect even more efficiency through shorter cleaning times, lower wear and quicker assembly times, including for covered plants. The basic concept upon which the new Mobilmix 2.5 is built has proven itself over the past 18 years in demanding applications on all continents. More than 300 plants of the previous generation were delivered worldwide.
One of the new Mobilmix 2.5 features is a lowered mixer platform. The slight slope to the discharge hopper simplifies cleaning significantly, as do the improved spatial conditions and accessibility to the mixer system. A new keyless security system on the mixer access hatch eases access for cleaning work.
Also, a feed flap on the skip as well as dust filter systems provide maximum dust protection around the mixer platform. The special design of the skip with parallel designed running surfaces and plastic rollers on the skip ensure comfortable operation with minimum wear and tear. Galvanised assemblies and quality components improve durability. The vast majority of projects such as tunnels, motorways and airport construction requires a mobile mixing plant.
Additionally, ready mix concrete companies require mobile mixing plants to react quickly to changing market demands in a timely manner. Quick assembly and ease of transport means the Mobilmix 2.5 meets this requirement. The Mobilmix 2.5 plant and in-line silo can be assembled and the electricity connected in a single day.
The basic elements are positioned on a supporting platform which is transported as a whole on a flatbed truck. The container with the control system is also integrated in this module. The base unit with the mixer system, weighing system and skip is lifted with a crane and unfolded and bolted in working position.
The control container offers generous spatial conditions and is equipped with the modern Litronic-MPS micro-processor control system by Liebherr. Two additional transportation units provide the in-line silo and the support unit with dosing valves and weighing belt. Up to 140m³ aggregates can be stored in four or six chambers in the in-line silo. The chamber width of 3,5m eases feeding with a wheeled loader.
On the second day, the cement silos are set up and electrically connected. A maximum of six cement silos can be set up, each with up to 120tonne capacity.
The new generation of Liebherr twin-shaft mixer has been completely reworked and now uses the new DW 2.5. All functional assemblies like electric motors, gears, hydraulics, mixer gate, central lubrication or high pressure cleaning system are placed close together for easy overview.
For service work on the mixer, only one of the four sides requires access. Hose and cable paths have been shortened significantly and also simplified. The reduction of hoses, corners and edges reduces the effort needed for cleaning. Gears are equipped with a directed oil rinse to bearing points that are under stress. Also, a radiator forces air from the fan blades into the belt pulley. Because of these efficiencies, operating safety is maintained even in very hot climates.
Changing the wear tiles is now also even easier because all screws are now accessible directly from the outside.
Mobile concrete supply
In Austria, SBM is working on mobile concrete supply for the Express road S10 which has as a centrepiece the Götschka tunnel. With a length of 4.4km and a gradient of 3.6%, it is the longest three-lane tunnel in Europe. The ambitious express road building includes four tunnel sections, four underfloor sections as well as various engineering structures over the 22km project.
Two plants of the SBM series EUROMIX produce 605,000m³ shotcrete and structural concrete for tunnels - being created using in mining technique and cut-and-cover technique – as well as galleries, bridges and concrete pavements at the ASFINAG construction project S10 Mühlviertler Schnellstraße.
Since January 2012, two concrete mixing plants made by SBM Mineral Processing have been responsible for the complete concrete production at the large-scale construction project financed by ASFINAG in the north of the city Linz. The powerful plants EUROMIX 2000 and EUROMIX 3000 are producing up to 30,000m³ high-quality concrete each month.
As the modular, space-saving plant systems are completely autonomous and do not require concrete foundations, they fit into every construction site infrastructure. According to the plant concept the concrete logistics is positioned in front of the plants and the material logistics is behind the plants. The high-performance mixing plants are already prepared for heating and cooling operation, therefore they are ready to produce concrete after only one week of assembly time. The centrally controlled systems work together perfectly and fulfil the complete package of performance requirements even under most extreme conditions in all-year operation.
A major part of the excavated material of the tunnel is newly processed directly on the site to achieve high-quality grain sizes for concrete production. This avoids long distance transportation as well as high levels of noise, dust and air pollution.
