An extraordinary Stetter batching plant has recently been set up in Oestringen, in the state of Baden-Wuerttemberg. The V4-plant of W. Mayer Transportbetonwerk GmbH is equipped with two 4 m³ twin-shaft mixers and with numerous, in some cases striking, equipment options. Alongside its six cement silos, the basic system contains an aggregate silo boasting a storage volume of more than 1000 m³ with a diameter of 10.24 m. The silo is stationed on top of a fully galvanised steel structure, in which the mixers and the weighing platform are positioned. The loading hall with roller shutters was erected as a technical noise protection measure. As a result, the truck-mixers can be filled in an enclosed room. An exhaust extraction system serves to protect the employees. Furthermore the batching plant is set up according to the “one-way” principle, meaning that all driving movements on the premises including the truck-mixer loading run in one direction of travel. This solution guarantees a high level of traffic safety, in addition to simplifying workflows while maintaining the same degree of efficiency.
