The Planetary Ball Mill PM 100 CM is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch.

The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short grinding times.

The PM 100 CM operates in centrifugal mode which leads to a more gentle size reduction process with less abrasion.

The mill can be found in virtually all industries where the quality control process places the highest demands on purity, speed, fineness and reproducibility.

It is ideally suited for research applications or ultrafine colloidal grinding, as well as for routine tasks such as mixing and homogenizing soft, hard, brittle or fibrous materials.

德國RETSCH（萊馳） 行星式球磨儀作用原理

行星式球磨儀的研磨罐位于底部太陽輪的偏心位置。研磨罐繞軸自轉，與公共的太陽輪轉動方向正好想法，太陽輪與研磨罐的轉速比為1：-1。研磨罐中的球在于研磨罐一起運動時受到Coriolis力（即自轉偏向力）的疊加影響。研磨罐和研磨球的運動速度之差產生強摩擦力和撞擊力，因而釋放了大量的動能。這種撞擊和摩擦的組合使得行星式球磨儀研磨時的粉碎度及高。 為了保持運動時的平衡，擁有一個研磨工位的行星式球磨儀需要配重。PM100CM型行星式球磨儀的配重可在一條傾斜的導軌上調整。不同大小的研磨罐的不同重心高度由此得到精確的補償，從而避免了儀器運行時的晃動和振蕩。 剩余的振動可以通過儀器底座的微小自由運動（底座自由力補償）得到補償。這種新型的FFCS技術基于d’Alembert原理，允許機身作很小的回旋運動，自動完成質量補償。實驗桌面只受到儀器底座產生的微小摩擦力。 PM100CM型行星式球磨儀運行時安靜、安全，即使在罐內振動達到最大時仍能保證優的振動補償，因此可置于實驗室桌面，無需監護。
