1. Introduction. High energy ball milling (HEBM) is known as an economic, simple and yet powerful method for the production of nanostructured and amorphous materials [1].The prolonged milling of powder mixtures, results in the formation of supersaturated solid solution, nonequilibrium intermetallic compounds as well as the formation of silicides, nitrides, stable or unstable carbides [2].

Ball milling is widely preferred for aluminumbased matrix composites to mix/blend the two different sizes and shapes of powders (matrix + reinforcement) in varying volumes or weight percentages following other optimization techniques. Moreover, the ball mill's input parameters substantially affect the blended powder flow properties [614].

Ball milling dramatically increased Cr(VI) removal by the biochar composites and the adsorption capacities reached more than and mg/g for BMFeHC and BMFeBB, respectively. For each of the three time intervals, Cr(VI) removal by the ballmilled composites was about double that of the corresponding unmilled samples. These results
When the ballmilling time is 24 h, CoCrW alloy powder is sintered after ball milling. The reinforcing phases are mainly in situ autogenerated M 6 C type carbides, which are blocky with the size of 110 μm. However, due to the relatively short milling time, the M 6 C carbides tended to be segregated.

Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.
Mechanochemistry using ball mills is a promising technique with applications in organic and inorganic chemistry as well as material sciences [14].During ball milling, up to 80 % of the energy that is generated in the mill is dissipated as heat [].This is why measurement and control of the temperature in the ball mills is important, for example, if heatsensitive products are formed that ...

After adsorption, part of adsorbed Cr(VI) was reduced by Fe(II) and then stabilized by Fe(III) in the form of amorphous Cr x Fe 1x (OH) 3 on the composite surface. All the results demonstrate that novel ballmilled biochar/iron oxide composites can be used as an effective adsorbent to remove Cr(VI) from water.
