Jul 17, 2012 We routinely recommend two ways coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25 full of potassium nitrate. Turn the mill on and come back in an hour.

Ball Cost For Coal Slurry Ball Mill

3 and Figure 6 illustrate the ground coal particle size by water jet mill and ball mill respectively. Calculation was made by the output of less than 11.55 m coal fines. The results show that the output per hour for the water jet mill is much higher than that of the ball mill, and the power consumption much lower than that of the latter.
