The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times. The PM 400 is a robust floor model with 4 grinding stations. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.
During the operation of the planetary ball mill, it generates an extremely high level of impact energy between the grinding balls and the grinding jars, allowing it to complete the sample grinding in a very short duration. The fundamental principle of the planetary ball mill hinges on the relative rotation of the sun wheel and the grinding jar.
The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...

Burmeister et al. modelled the stressing conditions of dry grinding in planetary ball mills based on DEM and validated the model by comparing the measured and calculated input power values [13 ...
The operating principle in the planetary ball mill is as follows: either four or two vials are settled symmetrically on a planetary disk. Each vial rotates around its center C, as well as around the origin O located at the center of the planetary disk in the opposite direction (Fig. 1); such movement confers high kinetic energy to the ball.
Several types of ball mill exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from litres for planetary ball mill, mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills. Pharmaceutical uses of Ball Mill
The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process.

in terms of geometry and working principles (see Fig. 1 and [8]), the versatility and efficiency of the planetary ball mill depend very much on the appropriate tuning of a multitude of milling variables. Among the others, the number and size of the balls, the jar geometry and the velocity of revolving parts should certainly be mentioned.
