energy in grinding in ball mill

Quantifying the energy efficiency of fine grinding
In 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

Best energy consumptionCemNet
Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill

High Energy Ball Mills Instead of Planetary Ball Mills
The Emax is not a Planetary Ball Millit is much more. Higher speed less warming finer particles faster grinding procedures. The high energy input in combination with the unique cooling system provides perfect conditions for effective mechanical alloying or grinding down to the nanometer range. To sum it up the Emax is fasterfiner
