Dec 15, 2012 The main difference between a ball mill that is typically used in minerals processing and a bead mill that is common in bioprocessing is the absence of stirrer in ball mills. For this current study a pilot scale ball mill that had a capacity to process up to 6 L of concentrated biomass slurry was constructed as shown in Fig. 1.
Jan 01, 1992 Here each change of energy per unit mass is followed by a certain Comminution in agitated ball mills is caused by the motion of the grinding beads. The higher the agitator speed is the more intense is the motion and with it the forces effective for cell disruption. With increasing agitator speed the measurable torque rises.
