A cooling system for a ball mill used for production of a lead oxide is disclosed. The system has an internal nozzle configured to introduce water into an interior of a rotating ball mill drum, and a water conduit on an exterior of the rotating drum and configured for external water delivery so as to deliver water on the drum exterior. A control system may also be provided for control of the cooling system. A method is also disclosed.
