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(guó)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(yáng)輪的偏心位置。研磨罐繞軸自轉(zhuǎn)，與公共的太陽(yáng)輪轉(zhuǎn)動(dòng)方向正好想法，太陽(yáng)輪與研磨罐的轉(zhuǎn)速比為1：-1。研磨罐中的球在于研磨罐一起運(yùn)動(dòng)時(shí)受到Coriolis力（即自轉(zhuǎn)偏向力）的疊加影響。研磨罐和研磨球的運(yùn)動(dòng)速度之差產(chǎn)生強(qiáng)摩擦力和撞擊力，因而釋放了大量的動(dòng)能。這種撞擊和摩擦的組合使得行星式球磨儀研磨時(shí)的粉碎度及高。 為了保持運(yùn)動(dòng)時(shí)的平衡，擁有一個(gè)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(dǎo)軌上調(diào)整。不同大小的研磨罐的不同重心高度由此得到精確的補(bǔ)償，從而避免了儀器運(yùn)行時(shí)的晃動(dòng)和振蕩。 剩余的振動(dòng)可以通過儀器底座的微小自由運(yùn)動(dòng)（底座自由力補(bǔ)償）得到補(bǔ)償。這種新型的FFCS技術(shù)基于d’Alembert原理，允許機(jī)身作很小的回旋運(yùn)動(dòng)，自動(dòng)完成質(zhì)量補(bǔ)償。實(shí)驗(yàn)桌面只受到儀器底座產(chǎn)生的微小摩擦力。 PM100CM型行星式球磨儀運(yùn)行時(shí)安靜、安全，即使在罐內(nèi)振動(dòng)達(dá)到最大時(shí)仍能保證優(yōu)的振動(dòng)補(bǔ)償，因此可置于實(shí)驗(yàn)室桌面，無需監(jiān)護(hù)。
