Entwicklung eines Condition-Monitoring-Systems auf Basis einer Belastungsanalyse am Beispiel eines Beraubers

Due to global growth, the worldwide demand for raw materials is steadily increasing. In the past, efficiency gains could be gained through the mechanization of mining. Today, automation and digitization are being focussed. A fundamental condition for increasing the level of automation in mining is the collection and monitoring of process information. This is the only way to ensure that the machines are optimally utilized without being exposed to excessive wear due to high loads. For many machines established on the market, the process loads are still not well known. In particular with regard to the progressing automation, this circumstance must be brought into focus by the machine manufacturers. Critical operating situations can only be detected and avoided by recording the actual process loads and developing a suitable warning system. For many machines in the mining sector, this approach has not yet been rigorously pursued. In the present work the systematic development of a condition monitoring system for a scaler is presented. The focus is set on the mechanical structure of the machine. First, the process of scaling and the underlying machine technology is presented in detail. Based on a measurement, the process loads are recorded and separated into different working modes. The analysis of the system provides the basis for the development of a condition monitoring system. The development of the condition monitoring system involves two steps: the derivation of the algorithms and the development of a suitable measuring system. Both, the algorithms and the measuring system, are verified by means of laboratory tests and based on the measurement data resulting from the operational measurement. The essential findings with regard to the development of the condition monitoring system are summarized and discussed. Finally an outlook for the optimization potentials of the developed system is given
