Frequently Asked Questions

1. How to Select the Right Grinding Jars and Balls?
   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 grinding jars and balls, energy input, rotation speed, brittleness of the sample material, and temperature in the jar during grinding et al. Please refer to the following table may help you in understanding the process in more detail. For any other questions or concerns in your specific grinding process, Please contact us to discuss in more details. Please click here for a wide variety of grinding jars and balls available in stock.

2. 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.

3. I would like to know if the grinding jars can be installed on our planetary ball mill?
