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 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, you are  welcome to contact us to discuss in more details.  MicroNano Tools has a wide variety of grinding jars and balls available in stock.
