    Jun 01, 2008 The grinding power consumption of the mill is 227 kW, calculated from Eq. (11) when the mill is running under stable conditions. A motor with 110 kW standard power was used for the mill in its initial design. In semi-industrial tests, however, the mill stopped for lack of power when approaching the specification load gradually
