Through conveyor, the raw material goes to the feeding system of the ball mill. The accuracy of the weighing and feeding system should be ± 0.5%. The ball mill offers size reduction as well as the mixing of raw materials. The ball mill used is the single compartment continuous type. The time of ball milling depends on feed size.

In their experiment, PbO was added in the fly ash and CaO mixture. The planetary ball mill was operated at 700 rpm for at least 2 h to ensure dioxin degradation, with a 15-min cooling interval every 15 min. After mechanochemical treatment, the residue was removed from the pots for Pb leaching tests and also used as a component in cement.
