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.
Plant with a 3 t mixer, a mixing capacity of up to 240 t/h and a loading silo of 109 t.
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.
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.
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.
