The load acted by grinding balls on lignocellulosic biomass is considerably higher, compared to the conventional ball mill and planetary ball mill. Important factors affecting the impact forces acting on the powders are the rate of milling, vibrational frequency, the amplitude of vibration, and the mass of the grinding balls [ 33, 47, 48 ].

The mill's action — for example, the motion of a grinding bowl in a high-speed planetary ball mill — generates high-energy shear forces to fracture already small particles into nanoparticles as they circulate with the grinding media. The smaller the milling media size, the smaller the final particle size.
