The recovery of lead from PLZT ((Pb 0.9 La 0.1)(Zr 0.52 Ti 0.48)O 3) ceramics was investigated by the wet ball-mill method using 1.4-11.3MH 2 SO 4 aqueous solutions. The wet ball-mill treatment was performed in a pot mill apparatus at room temperature for 0-72h with a rotational speed fixed at 300rpm.

Compact Lab Planetary Ball Mill (50-5000 mL Jars) for Li-ion Battery. 1. It has four ball grinding tanks installed on one turning plate. When the plate rotates, the tank axis makes the planetary rotation in opposite directions and the balls in the tanks grind and mix samples in high-speed movement.

Cryogenic planetary laboratory ball milling is composed of planetary ball mill and refrigeration device. Most of materials are heating-up because of friction and exothermal reaction in process of grinding at high speed, which may cause changing of chemical and physical properties of materials and lead to negative effect of grinding.

The reduction of an ammonium nitrate solution by lead pellets during wet ball milling was studied, as a method of removing concentrated NO 3 − from wastewater. Metal oxides forming on the surface of lead pellets in a ball mill reactor are continuously removed by contact between the pellets.
