planetary ball mill allows gentle size reduction

Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for …

Length reduction in the planetary ball mill invariably resulted in materials with higher specific surface area (up to 340 m 2 g −1) and a significant increase in surface fractal dimension (above 2.70). Since the specific surface area measures the amount of primary adsorption sites, this indicates that the morphology of the material underwent ...

Speed range of 6,000 to 18,000 rpm Gentle, rapid size reduction via 2-step process High throughput Quiet, reliable, easy-to-clean The ZM 200 Ultra-Centrifugal Grinding Mill rapidly reduces soft to medium-hard and fibrous materials to analytical sample size.

The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight …

This results in a different ball movement which leads to a more gentle size reduction process with less abrasion. Type PM 200 The benchtop model PM 200 with 2 grinding stations for grinding jars with a nominal volume of 12 to 125 ml. The larger sun wheel diameter results in a higher energy input when com- pared to the PM 100.

For a planetary micro mill to allow a comminution far below the required range of particle size for chromatographic methods important parameters will have to be considered, such as, amount of liquid, grinding ball size as well as grinding duration and rotational speeds. Figure 2.

Usually, various size reduction principles are combined in one mill, such as impact and friction in planetary ball mills or shearing and impact in rotor mills. Hard and brittle samples are pulverized best by pressure, impact, and friction. These size reduction principles, however, have only limited effect on fibrous, soft, elastic samples.

play a vital role. Whereas in planetary ball mills shearing is the predominant size reduction principle, it is impact in mixer mills. Beside the type of mill, scientists had to re-evaluate parameters of "classical" chemical reactions, like concentration and temperature, when transferred to a ball mill, as these are
