sep 22, 2020 grinding machine has been widely used in gold mines in south africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball mills and rod mills.oct 21, 2019 autogenous mill and semi-autogenous mill and pebble mill, when such equipment selection, need to pay special attention to whether have good since the grinding medium in the run of mine ore, can use the meter to determine the ore grinding media since the grinding medium index, and through the data processing to determine the grinding medium, and oct 04, 2019 In the present work, vibration, acoustic and thermal signals were correlated to the semi-autogenous grinding mill working parameters such as total power and inlet water flow rate, and then these parameters were monitored using vibration, acoustic and thermal analyses. next, the influential controlling parameters were obtained to monitor the mill conditions via spss software and afterward
