筒磨机内料粒的破碎需要料粒与研磨体的冲撞和能够使料粒破碎的研磨体的充足能量。料粒与研磨体冲撞一次所破碎的数目依赖于研磨体与料粒尺寸之比。图1所示为磨机筒截面内直径为d的研磨体与尺寸为h的颗粒处于互相冲撞的极限位置。能够受到冲击的料粒
Crushing of the pellets in the barrel mill requires sufficient energy of the collision of the pellets with the grinding body and the grinding body which can break the grains. The amount of crushing that a shot collides with a mill body depends on the ratio of mill body to millimeter size. Figure 1 shows the grinding body with a diameter d in the cross-section of the mill cylinder and particles of size h at the extreme positions where they collide with each other. The impact can be pellets
