2012-8-20  Powder metallurgy has been widely used in the manufacturing of mechanical parts. A typical process of powder metallurgy is shown in Fig. 1. As shown in the schematic diagram, blending of powder particles is necessary before compacting. Ball milling is often used to mix powder particles and make them homogeneous. Mechanical alloying, well known as ball milling, is frequently used to improve

Powder Metallurgy an overview ScienceDirect Topics

A branch of powder metallurgy involves mechanical mixing during which a high energy ball milling process is utilized wherein the cold welding, fracture, and re-welding of the particles occur (Suryanarayana and Al-Aqeeli, 2013; Suryanarayana, 2011, 2001).In particular, this practice is favorable while producing those composites reinforced by nano-sized ceramic particles for breaking up the

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
