Benninghoven claims that its innovative asphalt transfer system boosts the capabilities of the firm’s ECO mixing plant range. The newly developed alternating chute unit is fitted to the firm’s ECO asphalt plant and is said to be a key development for the sector, with a patent pending.
The ECO asphalt plant is offered with output ranging from 100-320tonnes/hour and is said to combine the latest Benninghoven technology and quality. Designed for mobility, the plants fit inside standard shipping containers sizes, maximising mobility and versatility. The firm says that the ECO units can be operated as stationary plants, but can also handle fast location changes without problems.
Because all main components are designed in standard container dimensions, they can be easily transported by road, sea or rail. The plants are also said to be cost-efficient and effective, while offering optimum mix quality.
The firm says that the ECO plants feature maintenance-friendly, high-quality and durable components. Improved maintenance is achieved by large service openings, LED lighting, a simplified lubrication, good accessibility and the availability of an electric and compressed air connection for tools as well as an 800mm wide platform width.
Weighing and mixing is said to be efficient and a key development is its new alternating chute container. The firm relies on loading skip technology as a link between mixer and loading silo, with the skip volume corresponding to the volume of the mixer. The mixer drains the asphalt vertically downwards into the skip, which then positions itself vertically above the targeted loading silo pocket and drains the stored mixed goods vertically downwards. This is a proven technology for excluding segregations in the mixed goods.
But for the new ECO asphalt mixing plant range, Benninghoven has developed a new cost-efficient alternative to the skip track. The alternating chute unit features a purely mechanical structure which is not subject to malfunctions. The design means that no sensor system, motors or brakes are required, while reliability is ensured. The system is said to offer fast and load-free positioning for silo selection. Separation effects in the end product are minimised through cross mixing in the material transfer, while the proven geometry of the Benninghoven loading mixed materials storage silos ensures mass flow instead of core flow, further preventing segregation in the mix.
The firm claims efficient mixing due to the design of the mixer with its optimum fill level and large dimensions. The larger plants in the ECO range include cold and hot recycling feed, bag feed, foam bitumen, granulate feed, fibrous material feed and adhesive feed. Other important features include a key transfer system for increased safety, a large service opening on the mixer cabinet, purge air cleaning on the infra-red temperature sensor and oil lubrication and filtering for the compressor. The system also offers the choice of plug-in cables and permanent cable connections, while the plant features the latest version of the firm’s sophisticated BLS 3000 control package.
