ball mill to extract pb from scrap circuit board

a ball mill (Pavitest mill, model I-4227, Brazil). The powder produced after 8 minutes of milling was 1.6 kg of material finer than a 0.208mm particle size. Milling exploratory tests with the PCB material and the ball mill showed that 90% of the material was finer than 0.208mm particle size, even for milling times higher than 8 minutes.
