the ball mill is powered by a fairly robust DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. the motor was mounted using screws on only one side, which were deliberately left loose. this allows the motor to the mill. the mill needs to stop on a number of occasions for the replacement of parts of mill liners. these stoppages are also one of the major causes of mill downtime and corresponding production losses, which can be minimized by a cost-effective maintenance schedule for the optimum grouping of mill liners for combined replacement.
