Aug 12, 2021 The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8 , for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively.The mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
