The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.

planetary ball mill gearing result in very high pulverization energy and therefore short grinding times [10,11]. The type of planetary ball mill used in industry is the Retsch Planetary Ball mill PM100 [12]. Furthermore, the principles of horizontal ball mill operations are limited regarding the fineness of the powder after milling.

Mechanical milling by planetary ball mill was performed on the pre-alloyed Ni-Al system. The results obtained in this work are as follows: • Mechanical alloying Al3Ni2 (δ) and Al3Ni (ε) for 40 h gives amorphous phase and nanocrystal Al3Ni2 (δ). • The mechanical milling (MM) process for pre-alloyed powder mixture improves its sinterability.
