The present invention is directed toward a material handling, processing and milling facility which utilizes ball milling as a means for material grinding, mixing or mechanical alloying of materials. The system includes an automatic ball charging, agitating and indexing assembly, constructed and arranged to deagglomerate and directly distribute a plurality of grinding balls to the facility.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
Ball Charging Grinding Media Handling Automatic Ball Charge Handling Systems Safe sorting and handling of grinding media in the range 27mm to 150mm diameter. Tonnes of grinding media, normally in the form of steel balls, are consumed by all process plants having mills as part of their comminution process. The handling of heavy steel balls can
To load and unload these steel balls, kibble systems are used. This provides a safe and easier way to charge mill chutes or inlets. Dynamic Engineering can design kibble systems to suit your unique mining operation. An example of such a back up ball charging system is given below:

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
