Quartz was the material used to perform the experiment and was arranged into 3 monosizes namely 8 mm + mm, 4 mm + mm and2 mm + mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
WhatsApp: +86 18838072829The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
WhatsApp: +86 18838072829In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 µm, therefore the traditional marker size (75 µm) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
