| 摘要： | MARINI-ERMONT is offering two innovative new continuous flow type asphalt plants that offer a combination of versatility and mobility. The TSX model is designed to maximise RAP use as well as offering mobility, while the latest Explorer model is designed with a focus on ease of mobility and commissioning but can also use RAP in its feed. MARlNI-ERMONT's TSX plant benefits from a new, patented technology that allows up to 70% RAP in the feed to produce mix quickly and simply. The TSX follows on from the innovative TRX plant from the firm, which is able to use up to 100% RAP in the feed. The innovative design used in the TSX plant uses a parallel flow dryer drum that comprises three distinct zones, mounted in series with a synchronised twin-shaft mixer. The first of the three zones in the drum is the combustion zone. In this area, the burner flame generates hot gases to dry and heat the aggregates and RAP. In a second zone, the hot gases from the first zone exchange with the aggregates at first so as to dry and heat them, as well as to store extra energy in the aggregates and to lower the gas temperatures. This second zone also acts as a thermal shield to prevent any flame radiation into the third zone, where the RAP is fed into the drum via a recycling ring. The RAP is dried in this third zone using the DuoTHERM heat exchange process. Heat is exchanged between the RAP and the slightly overheated aggregates. At the same time, the gases are at moderate temperatures in this zone having previously exchanged heat with the aggregates. As this is a long zone in the drum, there is time for the RAP binder to migrate homogeneously over all of the aggregates. |
