The requirements for the technology for using recycled material was carefully evaluated and coordinated after several visits to sites in Italy and abroad. The “multivariable” system was the most convincing: It allows the production of asphaltic mixture from screened recycling material (mandatory on the Italian market today) which is added to the mixing process cold.
The BENNINGHOVEN control system allows the use of a high ratio of recycling material. At the same time, this concepts eliminates the risk of mistakes with respect to the grading curve of the recipe, any process oils (rejuvenators) to be used or the production temperature of the mixture.
To ensure production of a new high-quality asphalt, the system allows the user to adapt the quantities of the different aggregates, the rejuventator, filler and bitumen – which are required for the best possible grading curve – depending on the quality and ratio of the recycling material used.
To meet the customer’s requirements, a large-capacity loading silo (two chambers with 76 t each) was selected to keep waiting times during loading of lorries at the site as short as possible.
Other important features are the screen unit with 6-fold screening and a screen surface of over 46 m² and a hot bin section with a total capacity of 80 t for storing the hot screened material. This ensures an unparalleled flexibility when handling a variety of different recipes. In addition, it helps to minimise plant starts/stops not connected to planned production and to provide optimum service to customers arriving without registering beforehand.
Always with the objective of being a sourcing point for the Roman market for many years and to providing customers with the best possible service and maximum professionalism, Cicchetti was willing to make the investment for purchasing and installing this plant.
