The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis)

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 112-176 of the mill volume

Maximum power is drawn by a mill when the charge occupies approximately 50% by volume However, as seen in Figure 4, the power curve becomes very flat in the range above 45% As a result, mills are seldom run with charge levels greater than 45% In rod mills, the charge is swollen by particles of feed which separate the rods
