Sorting Plants for Mixed Construction Materials and Bulky Waste

The large-volume material mix with a particularly high density requires an especially robust plant construction with high-performance components. In order to satisfy these requirements, STADLER has developed a true powerhouse – the ballistic separator STT6000 – specifically for this type of plant.

STADLER experience

“Be it construction waste or bulky waste sorting plants, this model example of a young and upcoming class clearly shows how STADLER is keeping up with the times – or is already ahead of them.”

Material properties

The material mix of construction materials or bulky waste consists of cardboard, wood, ferrous metals, minerals and films. It exhibits a density of approximately 250 to 350 kg/m³.

Example process description

All processes are constantly changing and are supplemented and refined by new technologies – such as the improvement of NIR technology or the use of sorting robots for example.

STADLER always endeavours to deliver the latest technology to the customer. Our ballistic separator STT6000 is particularly well-suited for construction waste and bulky waste, and allows material feeding of very large as well as non-shredded parts. Thanks to its performance capability, the STT6000 is often used at the start of the line. An infeed hopper doses the material, which is then separated by ballistic separators (either pre-shredded or as a whole) into different grain sizes and shapes over the course of several stages, in order to achieve the desired sorting purity during the subsequent optical recognition. Manual or robotic re-sorting then takes place depending on the requirements.
