Parametercharakterisierung eines ballistischen Separators

This master's thesis deals with the parameter-based characterisation of a ballistic separator. The aim is to determine the dependence of the separation performance of ballistic separators on the adjustable parameters of paddle speed, paddle angle and the blower of the unit based on the purity and material output. The influence of the machine parameters can be determined by varying them during large-scale tests. Three sensor systems were used to determine the separation performance of the ballistic separator, the data from which was collected and subsequently analysed. This included analysing the masses and the data obtained from NIR sensors and an RFID measuring system. The evaluation of the data obtained from the sensor systems was used to determine the dependencies between the output and purity of a material (wood) and the adjustable parameters and to subsequently compare these results. By comparing the results and the characteristics of the measurement methods, a recommendation can be made for implementation in existing and newly constructed plants. As a result, the dependent separation performance can be used to intervene in the plant and changes can be made to influence the output flows of the ballistic separator. Depending on the input material, it is possible to change the operating mode of ballistic separators, making a dynamic plant possible in the future. Changing the adjustable parameters opens up the possibility of focussing on one of the streams, such as the 3D stream, in order to be able to treat it better in downstream units. This enables improved recycling, which can drive the transition to a circular economy.
