The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The SMZVI was prepared by ball-milling the industrially reduced iron powders. Briefly, the industrially oxidized scales was reduced into the iron powders in H2, and then the powers were through the 320 mesh sieve and ball-milled for about 120 h by the steel balls (ϕ 5−10 mm) in a ball mill under 7.5 kW power at room temperature.

Consider a ball tossed in the air. Our work first produces kinetic energy of motion. As the ball rises, the kinetic energy is converted to potential energy. At the top of the arc, all the energy is potential. As it falls back, the potential energy is converted back to kinetic energy—until it hits the floor. Then what happens to the energy?
