钢球抛落运动中,落点的动能起破碎作用,而落点的径向动能又起主要破碎作用。以各球层径向动能因子累积值最大为目标求得的转速率是球磨机的最优转速率。
Falling ball movement, the kinetic energy of the impact from the point of fragmentation, and the fall of the radial kinetic energy plays a major role in the crushing. The optimal rate of rotation of the ball mill is obtained by aiming at the maximum cumulative value of the radial kinetic energy of each ball.
