Mono Chamber Raw Mill Ball Charge Design. Hi experts, I want to design a ball charge for a monochamber raw mill in a white cement plant and wanted to know your opinion about it. The raw material is preground by to a hammer crusher and after separation by a third generation separator the course material is fed to the monochamber raw mill.
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.
Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
