Grind the calcined powder, add ethanol and grind it in a high-energy ball mill for 2 h, then keep it at 1200 °C for 8 h, and finally prepare Na 3+x Sc 2 P 3-x Si x O 12 (x=0, 0.5, 1.0) powder. Before use, dry the self-made Na 3+x Sc 2 P 3-x Si x O 12 (x=0, 0.5, 1.0) powder in a vacuum environment at 80 °C for 24 h.

discharge ball mill converts about 20% more energy than an overflow discharge mill with the same shell dimensions. Ball mill shells are often furnish ed with two manholes. Ball mills - with small balls or cylpebs - can produce the finest product of all tumbling mills. 80% minus 74 microns is a normal require ment from the concentrators.

Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
