  • Identifying grinding mill dynamics using acoustic

    The dynamic charge behaviour within mills is the key metric for operational diagnostics. As shown in Fig. 2 under relatively stable ore ball water and recycle feed rates overthrow of the charge will cause extensive wear on mill liners whereas reduction in throughput is resulted when underthrow is exhibited.Studies have been conducted to develop on-line measurement solutions for charge
