Figure 5: Movement states of the ﬁlling In our lab course, we will work with a centrifugal ball mill. The feedstock can be ﬁlled up to 10 mm and will be milled to particles of about 1 μm. The mill consumes a maximum power of 100 W. (Do not assume the mill produces 100W of comminution power) In Fig. 6 the parts of the mill .A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a .
