bauma CTT Russia 2018: The BENNINGHOVEN mixing plant ECO - Perfectly simple.
BENNINGHOVEN ECO asphalt mixing plant.
The type ECO asphalt mixing plant in capacity sizes from 100 - 320 t/h combines state-of-the-art, innovative Benninghoven technologies and a high standard of manufacturing in compact container sizes. This ensures maximum mobility and flexibility: Type ECO systems can be operated as stationary systems, but can also handle rapid location changes without problems.
Because all main components are designed in ISO standard container dimensions (20 or 40 foot), transport by lorry, ship or rail is easy. The strengths of the plants are their ability to be transported worldwide and that they can be designed as simply, cost-efficiently and effectively as possible. The powerful plants with fixed options ensure optimum mixture quality.
As all Benninghoven plants, the ECO plants feature maintenance-friendly, high-quality and durable components. In detail, the increased ease of maintenance means: large service openings, optimum illumination of work and maintenance areas thanks to LED technology, an intuitive traffic light lubrication plan, excellent accessibility in all areas, availability of an electric and compressed air connection for tools and maintenance work, surrounding 800 mm walking and work platform width – to name just a few.
Asphalt transfer within the plant with alternating chute unit
Benninghoven has always relied on the loading skip technology as a link between mixer and loading silo, whereby the skip volume corresponds to the volume of the mixer. The mixer drains the asphalt vertically downwards into the skip, the skip then positions itself vertically above the targeted loading silo pocket and again drains the stored mixture vertically downwards. This is a proven technology for excluding segregations in the mixture.
For the new ECO asphalt mixing plant range, Benninghoven has a new, more cost-effective alternative to the skip track and had it patented. The new mixed material diverter chute unit is purely mechanical, reducing the likelihood of malfunction. A new smart design means that no sensor system, motors, brakes, etc. are required, while worldwide functional reliability is ensured. Another point worth mentioning is the fast and load-free positioning for silo selection. Separation effects in the end product are minimised through active cross mixing in the material transfer on the one hand, while on the other hand the proven geometry of the Benninghoven loading silos ensures segregation in the mixture.
Weighing and mixing section
Best mixture quality thanks to optimum fill level of the mixer and optimum mixing through the generously dimensioned mixer geometry. From plant size ECO 2000, all weighing and mixing sections are already equipped with the following interfaces: cold and hot recycling feed, bag feed unit, foam bitumen, granulate dosing system, fibre feed system and adhesive system. Whether from the outset or for retrofitting later on – the plant is already prepared with all interfaces.
Additional highlights of the new weighing and mixing section:
- Key transfer system for increased safety
- Large service opening on the mixer cabinet, H x W = 600 x 1200 mm
- Individual colour options (from standard to individual)
- Transport-optimised container dimensions
- Purge air cleaning on the IR temperature sensor (reliable measurement of asphalt temperature)
- Central compressed air maintenance unit (oiler and separator/filter)
- Modular expansion of functions through bus system
- Choice option between plug-in cables and permanent connection
- Weighing of virgin mineral not sensitive to disturbances (e.g. through water hammer) thanks to special scale design
- Optimum mineral scale utilisation also in bypass operation
The efficient and responsible handling of resources is becoming increasingly important – especially in road construction. Recycling of asphalt is becoming ever more important. The principle is absolutely obvious and extremely lucrative: not only does recycling save limited resources, it also clearly lowers costs while increasing efficiency. After all, newly processed rock – so-called mineral – is more expensive compared to reclaimed asphalt. As a competent partner, BENNINGHOVEN offers a wide range of products in the area of recycling feed systems. For cold feed systems, we can already achieve additive rates of up to 40 % with different technologies, from addition to the dryer drum or mixer feed to multi-variable feed. Whether on our own systems or on third-party systems, whether for retrofitting or expanding an existing hot feed system to maximise flexibility.
