Powder Metallurgy
Powder metallurgy is an ancient method that is a predecessor of the widely used ingot metallurgy or general castings. The motivation is due to human kind's limita-tions to achieve high temperatures capable of melting materials as well as to build crucibles to hold the liquid melts [2]. It is known that in 3000 BC the Egyptians

Ball Mill
According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.
