Deliver information about in-mill dynamics has been developed by Magotteaux. It can provide online and accurate measurements of the degree of grinding ball fill and pulp position for timely decision making and actions. This tool could be used on its own or linked to an automatic grinding ball loading system named Magoload.
To include SAG and Ball milling. The hardness of each sample was measured in terms of SAG power index, SPI for SAG grinding and Bond Ball mill work index, BWi for ball mill grinding. A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG mill feed size Kosick and Bennett, 2001.
Fine Grinding With A Ball Mill Pdf Fine Grinding as Enabling Technology The IsaMill. Table 1 Power Intensity of Different Grinding Devices Ball Mill is a 5.6m D x 6.4m L 2.6MW Tower Mill is a 2.5m D x 2.5m L 520KW Table 2 Mill Comparison of Media Size, Power Intensity, number of grinding media The ability to use smaller media is probably the dominant impact on grinding efficiency.
However, the total mill power consumption dropped 8 from an average of 7600 kW to 7000 kW. The mill work index dropped 10 percent from an average of 5.5 kW-hrT to 5.0 kW-hrT. Conclusions This represents a current view of the effects of grinding ball fragments in the milling circuit and the impact on the crushing and grinding circuit.
