  • Why the ball to powder ratio (BPR) is insufficient for

    The ball to powder ratio (BPR) is a processing parameter that is frequently used in both mechanical (ball) milling and mechanical alloying A number of recent studies provided the BPR as a principal milling parameter while neglecting other parameters, such the vial volume, the diameter and quantity of milling balls and the powder massThe importance of this new parameter for ball milling process, filling ratio of vial, was investigated in this study For this purpose, Al–Fe2O3 thermite mixture was used as the startingFilling ratio of vial: An important parameter for ballAs for as ball to powder ratio is concerned, if the purpose is mixing you should go for 510 ration of ball with powder In case if you want to reduce the size or ally the powder then select highBest way to determine the balltopowder ratio in ball

  • Why the ball to powder ratio (BPR) is insufficient for

    Magnesium hydride powder (ABCR Germany, 98%) was milled in a Fritsh P7 premiumline planetary ball mill The milling process was performed with different parameters, including the ball and powder mass, total milling time and number of cycles, but the ball to powder ratio (BPR) was kept constant in all cases The resulting BPR was 62The powder was produced by planetary ball milling process 15 ml alcohol was added into each ball mill tank, and the ball milling ratio was 30:1 The ball milling speed was kept at 150 rpm (revolutions per minute) The ball milling time was 7 h The powder was dried in a vacuum oven at 60 ℃ for 3 h before being removedInfluence of ball milling process on microstructure andThen, concerning the ball to powder ratio as well other parameters like milling time and rotation speed it depends on which particle size and grain size (nanostructure) you are interestedHow to calculate ball to powder ratio?
