Influence of the materials dispersity on amplitude of acoustic signals of the working zone
Journal Title: Комп’ютерне моделювання: аналіз, управління, оптимізація - Year 2017, Vol 1, Issue 1
Abstract
The work is dedicated to the research of particle size influence of gas-dispersible flows on amplitude of acoustic signals, both in the grinding process and in the bulk material transportation. The dependence of value amplitude of signals received when carrying out acoustic monitoring of process of jet grinding of different bulks (slag, quartz, chamotte) from particle size distribution of material is confirmed experimentally. Experimental studies have been carried out on the developed Granulometer-1 and Granulometer-2 devices for the transportation of materials in the energy carrier flow. A similar dependence has been established for the transport of bulk materials in the energy carrier flow, as well as for the grinding of materials. The equations of correlative communication of the maximum values of the amplitudes of the received acoustic signals with the particle size of the researched material (quartz, chamotte) which can form a basis of quality control of material in case of jet grinding of materials are received.
