Prototype for Measurement Tools for Evaluating the Crusher Feed using Digital Signal Processing

University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

Abstract: Nowadays, the use of digital signal processing is essential in various measurements of different machines. There has been many projects done at Sandvik AB on how to collect and measure data signals on the cone rock crusher. None of those measurements could present the correct data. The reason could possibly be due to the lack of theory behind the use of digital signal processing which this thesis will focus mostly on. In this thesis, a complete hardware prototype is constructed to measure the data signals of the cone crusher. The uneven distribution of the materials in the crushing chamber, results in uneven load which affects the machine performance negatively. Therefore, the signals obtained are analyzed and the results will be presented in real time mode using Matlab to investigate the cone crusher performance.
