Tips for grinding polymeric materials with a planetary ball mill

There are a few tricks for grinding polymeric materials using a planetary ball mill because of heat generated and accumulated during ball milling process. 
1. The material temperature may need to be cooled below Tg with liquid nitrogen or dry ice to let the material be brittle; 
2. The material may need to be ground with liquid nitrogen or dry ice or other liquids in wet grinding; 
3. Slower rotation speed and shorter milling time in order to avoid change of morphology of the material.

    How to Select the Right Materials of Grinding Jars and Balls for Planetary Ball Mill

    Selection of the materials of the grinding jars and balls mainly depends on the sample materials. Rule of thumb, the material of jars and/or balls must be harder than the sample material. Otherwise, it is actually the jars and balls which will be ground by the samples in the grinding process.  As a result, the material of the jars and balls will become contamination in your sample materials.   

    In order to make the grinding process more efficient and obtain samples with less contamination, there are many other factors to be considered, such as density of the materials of the...
