THE PHYSICS OF MECHANICAL ALLOYING IN A MODIFIED HORIZONTAL ROD MILL - MATHEMATICAL TREATMENT

Based on kinematic modelling of the modified horizontal rod mill (MHRM ), the kinematic equations giving the velocity and the acceleration of the rod in the cylinder of the mill are given. The kinetic energy tra nsferred at the collision event, the shock frequency and the injected shock power are also calculated. Comparison of calculations to some pr ior experimental results confirms our assumption published in earlier works which states that neither the shock energy nor the shock frequen cy separately taken into account, govern the end product but only the injected shock power is responsible for the microstructure and phases present in the processed powder.
