It is possible to calculate the grinding media average diameter formed in the mill operation, during grinding media unload from mill other enterprises. It is possible to obtain the necessary data on a grinding media granulometric composition from calculation of the power draw of dry multipartment ball mills 225 the mill load that is the volume of charge in the mill is the principal determinant of power draw estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous So direct measurement must be taken for calculation of mill load.In the present paper an effort is made to propose a simple and efficient model for the calculation of the specific grinding energy and another one, in combination with the first model, for the determination of the mill power draw, in which the bond work index is also embodied. the proposed models are then used for ball-mill scale-up purposes.
