with ball-to-powder ratio (BPR) equals to 1:2 and the diameters of balls were 10 mm. Then, these mixtures were milled for 2, 5, 10 h in a planetary ball mill (type MTI SFM (QM-3SP2)) with rotation speed equals to 350 rpm and ball-to-powder (BPR) weight ratio was 10:1. The milling was performed using Al 2 O 3 vial and balls. It
grinded so fine and a special mill (Braun KMM 30 mill), type 3045, CombiMax (Germany) then high energy planetary ball mill type MTI SFM (QM-3SP2) 250 rpm rotation was used to get ultra-fine powder (Nano form). The dried samples peels were dissolved in water with concentration of 1 g/10 ml hot water. 2. Determination of proximate composition Chemical

Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%
High-entropy alloys (HEAs) are promising structural materials due to their excellent comprehensive performances. The use of mechanically alloyed powders to deposit HEA coatings through atmospheric plasma spraying (APS) is an effective approach that can broaden the application areas of the HEAs. In this paper, a ductility–brittleness AlCoCrFeNiSi system was
