The electrical and electronic scrap is fed into a horizontal, rotating drum. Then the input material is moved upwards by the actuators inside the drum, and it falls down again after reaching a specific height. A throwing mechanism located in the fall path of the material catches and accelerates the falling material and throws it once again. The equipment is broken up by the force of the impact on the housing. While it is in the drum, the material spins upwards and from side to side several times. The SBB thus breaks up the equipment efficiently, quickly and carefully.
Valuable parts like PCBs and transformers stay intact and are easy to separate. Contaminated components like condensers, batteries and color cartridges also remain undamaged for easy separation from the process at an early stage.
