  • People also askDoes ball milling improve the circularity of powder particles?It can be seen that the circularity of ball-milled powder particles is significantly improved compared with the precursor powder. During ball milling, the particles were collided in different directions, which indicates that the impacting forces in different directions act on the sharp corners of the particles.

    link.springer/article/10.1007/s11666-021-01236-5What happens if you increase BPR in a ball mill?By further increasing the BPR to 20:1, the graphite content reduces to 0.84%. This is due to the fact that the fracture of the powder particles always happens along the graphite flakes in the ball milling process. Therefore, the larger BPR causes the severer fracture of the powders, which easily leads to the loss of the graphite.

    The ball-to-powder weight ratio has been a crucial parameter that correlates with kinetics. This ratio can be changed from low values as 1:1 to high values 220:1 (Kis-Varga 1996 ). At high ratio, the number of collisions increases, and more energy transfers, more heat originates, and so mechanical activation takes place faster.
