ball mill processing for nanocomposites

Fabrication of polymer nanocomposites via ball milling

Ball milling is based on the occurrence of collisions between the milling tools inside a batch reactor that contains materials in powder form , , , The collisions are a consequence of the reactor, or a part of it, moving , During each collision, a fraction of the powder is trapped between the colliding surfaces and subjected to mechanical load , , , as schematically shown in Fig 2a brief description regarding high energy ball mills Figure 1 A rock tumbler Ball mills The tumbler ball mill is a cylindrical container rotated about its axis in which balls impact upon the powder charge The balls may roll down the surface of the chamber in a series of parallelMechanical Milling: a Top Down Approach for the

Synthesis of nanocomposites and amorphous alloys by

Mechanical alloying (MA) is a powder metallurgy processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a highenergy ball mill Due to the specific advantages offered by this technique, MA was used to synthesize a variety of advanced materials This article presents two specific examples of synthesis of nanocomposites containing a high volumeAmongst the early studies of this technique, Prabhu et al employed a SPEX mill to synthesize AlAl 2 O 3 composite powders with volume fractions of 20%, 30% and 50% and found that the Al 2 O 3 reinforcement materials were distributed homogeneously in the Al matrix after 20 h of milling at a ballSynthesis and characterisation of advanced ballmilled Al
