The sample was then kept overnight in an oven for solvent evaporation and then ball-milled at 200 rpm for 3 h using a rotary ball-mill. The ball-milled substrate then went through an acetonitrile pyrolysis step for 2 h at 900 °C for the carbon growth process.

What's the Difference Between SAG Mill and Ball Mill

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Scale-up method of planetary ball mill

A total scale-up method for planetary mill is discussed in this section. All parameters ( d M, h and R) of the basic planetary mill were scaled-up as t p times to investigate the effect of the scale-up ratio on E i. The scale-up ratio was changed from 0.50 to 3.00 ( V M = 170 – 36 650 cm 3; n B = 80 –17 496).
