Charge dynamics in tumbling mills: simulation and measurements with an in-mill sensor Alatalo, Johanna Luleå University of Technology, Department of Civil, Environmental and Natural Resources Engineering, Sustainable Process Engineering.
These systems have included instrumented strain gauge bolts, piezo measurements on the side of the mill, analysis of the power signal of the mill, etc. Non-contact acoustic measurement (Pax, 2011) provides a unique opportunity to investigate the internal dynamics of a tumbling mill, since it is the particle interactions that give rise to the ...
tumbling mills In 1988, Professor Moys, from the University of the Witwatersrand in South Africa, published articles about the effect of slurry rheology and flow rate on mill behaviour. He had already highlighted the interaction between slurry and media in the mill by looking at the mill grinding efficiency. At
Here, a methodology is developed to simulate on-the-shell acoustic signal emitted from tumbling mills using the information extracted from a DEM simulator. The transfer function which links the forces exerted on the internal surface of the mill and the acoustic signal measured on .

Jan 01, 2007· The charge mass or the ball load inside the mill also influences the amplitude of the characteristic peaks of the vibration signals. To study the effect of mill filling on the vibration signature of tumbling mills, three experiments were carried out at different ball loads: 140, 180 and 220 kg corresponding to 45%, 58%, and 68% mill filling.
