Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3; In wet grinding, the solids concentration 1s typically 60% 75% by mass.

### Best way to determine the ball to powder ratio in ball

Popular Answers ( 2) Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21 24 % of the empty mill. Now, in order to get an efficient milling action, 80 110 % of the pores in the ball bed must be filled with the actual particles to be ground. Then, by doing simple calculation, the particles occupy 11.2 17.6 of the mill volume.
