详细介绍

产品介绍：

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.

行星式球磨仪 PM 100 CMWET GRINDING WITH THE PM 100 CM

Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.

To produce very fine particles below 1 micron by wet grinding, friction rather than impact is required. This is achieved by using a large number of small grinding balls which have a large surface and many friction points. The ideal filling level of the grinding jar should consist of 60 % small grinding balls.

The graphic shows the result of grinding zeolite microparticles at 600 rpm in the PM 100 CM. After 1.5 h of pulverization in isopropyl alcohol with 0.5 mm grinding balls, the D90 value of the original sample was reduced from 25 µm to 350 nm.

行星式球磨仪 PM 100 CM"COMFORT" GRINDING JARS FOR EXCELLENT RESULTS

The performance and the result of sample preparation are also determined by the choice of the grinding jar and its ball charge. The comfort range of grinding jars has been specially designed for extreme working conditions such as long-term trials, wet grinding, high mechanical loads and maximum speeds as well as for mechanical alloying.

Available jar sizes: 12 ml / 25 ml / 50 ml / 80 ml / 125 ml / 250 ml / 500 ml
Pressure-tight and dust-proof O-ring sealing prevents material spillage, even after clamping is released
Jars and balls available in 7 materials: hardened steel, stainless steel, tungsten carbide, agate, sintered aluminium oxide, silicon nitride, zirconium oxide
Stainless steel protective jacket for agate, sintered aluminum oxide, zirconium oxide and tungsten carbide grinding jars
A groove between jar body and lid allows for easy opening of the lid, e. g. with the help of a spatula, if there are underpressure effects inside the jar

JARS & LIDS FOR SPECIAL APPLICATIONS

For colloidal or wet grinding, the use of a grinding jar with a special closure device is recommended
Aeration lids are designed for working under inert atmosphere, for example if oxygen can influence the grinding process or the mechanosynthesis. The lids allow the introduction of gases like argon or nitrogen into the grinding jar.
Optional pressure and temperature measuring system PM GrindControl

行星式球磨仪 PM 100 CMRECOMMENDED JAR FILLINGS

To produce optimum grinding results, the jar size should be adapted to the sample amount to be processed. The grinding balls are ideally sized 3 times bigger than the largest sample piece. Following this rule of thumb, the number of grinding balls for each ball size and jar volume is indicated in the table below. To pulverize, for example, 200 ml of a sample consisting of 7 mm particles, a 500 ml jar and grinding balls sized at least 20 mm or larger are recommended. According to the table, 25 grinding balls are required.

Grinding jar nominal volume	Sample amount	Max. feed size	Recommended ball charge (pieces)
Grinding jar nominal volume	Sample amount	Max. feed size	Ø 5 mm	Ø 7 mm	Ø 10 mm	Ø 15 mm	Ø 20 mm	Ø 30 mm	Ø 40 mm

The table shows the recommended charges (in pieces) of differently sized grinding balls in relation to the grinding jar volume, sample amount and maximum feed size.

受样品材料性质和仪器配置/设定的影响

行星式球磨仪 PM 100 CM

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最优的振动补偿，因此可置于实验室桌面，无需监护。
