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.

德国RETSCH（莱驰） 行星式球磨仪作用原理

行星式球磨仪的研磨罐位于底部太阳轮的偏心位置。研磨罐绕轴自转，与公共的太阳轮转动方向正好想法，太阳轮与研磨罐的转速比为1：-1。研磨罐中的球在于研磨罐一起运动时受到Coriolis力（即自转偏向力）的叠加影响。研磨罐和研磨球的运动速度之差产生强摩擦力和撞击力，因而释放了大量的动能。这种撞击和摩擦的组合使得行星式球磨仪研磨时的粉碎度及高。 为了保持运动时的平衡，拥有一个研磨工位的行星式球磨仪需要配重。PM100CM型行星式球磨仪的配重可在一条倾斜的导轨上调整。不同大小的研磨罐的不同重心高度由此得到精确的补偿，从而避免了仪器运行时的晃动和振荡。 剩余的振动可以通过仪器底座的微小自由运动（底座自由力补偿）得到补偿。这种新型的FFCS技术基于d’Alembert原理，允许机身作很小的回旋运动，自动完成质量补偿。实验桌面只受到仪器底座产生的微小摩擦力。 PM100CM型行星式球磨仪运行时安静、安全，即使在罐内振动达到最大时仍能保证优的振动补偿，因此可置于实验室桌面，无需监护。
