Identifying grinding mill dynamics using acoustic
Acoustic measurements have been conducted using a microphone array located in the front of the mill, at 136 m from it (Fig 3 (a)) The array is composed of 64 1/4” GRAS 40 pH phase matched microphones (frequency range from 50 Hz to 10 kHz) Those microphones are mounted on a 2 m by 2 m perforated steel grid using plastic cable glands During the grinding process, sound signals are collected by an omnidirectional capacitance microphone (BSWA MP201) The frequency response range is from 63 Hz to 20 kHz, the open circuit sensitivity is 50 mV/Pa, and the dynamic range is from 17 to 146 dBA The microphone is located laterally at a distance of 50 cm from the grinding surfaceA novel soundbased belt condition monitoring The machining methods are mostly grinding techniques described in a detailed manner in [12,13,14] Two main versions of this technique are the burr and disc grinding In the current paper both methods are investigated by laboratory tests and numerical tools using Assessment of grinding weld treatment methods
