The volume of the steel milling chamber of the planetary and attrition mill was 0.25 and 0.5 L, respectively. Milling chambers contained 150 g (planetary ball mill) or 2000 g (attritor mill) of iron balls with a diameter of 2 mm. Initial experiments were performed both in dry and wet mode.
Attritor Mill An attritor is a ball mill system in which the balls, together with the material to be milled are set in motion by a shaft with stirring arms, rotating 100-2000rpm. Cylindrical vessel is usualy water cooled because of the considerable heat generated by the process. Dry,wet (water, inorganic liquids) milling is possible inert gas

pure Al during attrition ball milling depend on milling time. Reinforcement of pure aluminum and Al/B4C based composites with CNT and attrition milling times over 12 h show low effect on mechanical properties. During attrition high-energy ball-milling CNT-s were embedded, cold-welded between the Al particles and fractured.

In mechanical milling, stearic acid can be used as a process control agent to reduce the interface energy between powders and contribute to the crushing of powder particulates. In this study, a super-hydrophobic coating with a contact angle of 153° ± 2° was fabricated by ball milling a copper powder and stearic acid mixture onto an aluminum foil. Fourier-transform infrared spectroscopy ...

Mechanical attrition by ball-milling has been widely used to prepare nanocrystalline materials in the laboratory scale [].It has also been extensively used to prepare mechanically alloyed equilibrium and non-equilibrium alloy phases starting from blended elemental or pre-alloyed powders [].The deformation experienced by the materials during the preparation of its nanocrystalline form ...
Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..

Cu-Zn alloy was prepared by high-energy ball milling of elemental copper and zinc powders by the attrition mill. The different parameters, such as milling time, ball-to-powder ratio, and milling speeds, were optimized. The results show that different milling …
Copper alloys with different amounts of zinc were synthesized via high energy ball milling at liquid nitrogen and room temperature. Bulk samples were produced in situ by controlling the milling temperature. It is shown that temperature plays an important role in formation of artifact-free consolidated samples via its effect on defect formation and annihilation during the milling process. …
