Grinding Media Charge Motion inside Mill. The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the aspects of the dynamics of the

Ball Charging & Grinding Media Handling Automatic Ball Charge Handling Systems Safe sorting and handling of grinding media in the range 27mm to 150mm diameter.

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising

The specific charge of the drum with grinding media is expressed by the report between the volume of charge and the inside volume of the drum, or aria of cross section of the charge Ainc and aria of cross section of the drum At (fig.1) [5]. t inc t inc A A V V ϕ= = (3) This parameter is usually expressed in
