– Energy required to reduce the size of particles is directly proportional to the ratio of the initial size of a typical dimension to the final size of that dimension E = K. k ln (D f/D p) E – Energy required per mass of feed . K. k – Kick's constant D. f – Average initial size of feed . D. p – Average size of product . D. f / D p – Size reduction ratio • Coarse grinding has ...
احصل على السعرThis represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communiions). .

احصل على السعرIn Figure 1a, both PSD graphs show the typical 'shoulder' (range 110μm) coming from the limestone. The clinker in the ball mill is clearly less ground than in the VRM, which will result in lower mechanical strength. Although the VRM grinds the clinker to a higher degree, the fineness of the limestone is not increased proportionally.
