Feb 16, 2000 the acoustic emission signal propagates well through solid material. acoustic emission waves are either shear or longitudinal. any internal surfaces, i.e., cracks or inclusions, will distort and damp these waves. a single grain in a conventional grinding wheel will produce an acoustic emission burst propagating through the wheel.
Different types of rocks generate acoustic emission ae signals with various frequencies and amplitudes. how to determine rock types by their ae characteristics in field monitoring is also useful to understand their mechanical behaviors. different types of rock specimens granulite, granite, limestone, and siltstone were subjected to uniaxial compression until failure, and their ae signals grinding mill.Jan 01, 2000 in the professional literature it is often suggested that for the on-line characterization of a grinding process, the acoustic emission ae should be applied because it is intensively generated by grinding processes and can be simply detected on-line , , . the aim of this paper is to show how a non-contact method for on-line estimation of profile auto-correlation function from ae signals can in fact be grinding mill.
