noise dilemma of grinding mill

The role of the ore in absorbing noise energy is suggested as a possible control variable for the grinding process and as an indicator of product size distribution. The relationship between ore types and mill noise is also examined and, under conditions of wet grinding, it is demonstrated that mill noise analysis can indicate ore type and may

    an analysis of mill grinding noise sciencedirect

    Jan 01, 1985 · The available energy of a mill for grinding is governed largely by the mill speed, ball charge and ball size. Again these parameters are reflected to some extent by noise levels and it is suggested that the reduction from mill/ball-only noise levels caused by the introduction of ore could be an indicator of coarse breakage and type of breakage

    Abstract. The noise generated by a ball mill during a batch grinding operation is investigated and the results show that, for a given ore, the noise levels may vary with time of grind, ore charge weight and mill speed. The role of the ore in absorbing noise energy is suggested as a possible control variable for the grinding process and as an indicator of product size distribution

    In addition, the mill noise is shown to indicate the actual effective pulp viscosity in the mill and hence permit the identification of the dynamic rheological regime existing in the mill. It is demonstrated that mill noise increases with grind time and, at any given grind time, with increasing pulp density in the pseudoplastic range
