Working Principle

The PBM-04 planetary ball mills have four grinding stations rotating around a sunwheel.  When the sunwheel rotates, the station axis makes planetary rotation in opposite directions and the balls in the jars are subject to superimposed rotational movements. The speed difference between the grind balls and the grinding jars produces high-energy impacts,  which are used to comminute the material samples. Minimum granularity of the final product can be as small as 0.1 micron.

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.

Reference table on how to select grinding jar and ball for ball mill

2. How many grinding balls should  be used for different sizes of grinding jars? 

Number of grinding balls

The numbers of grinding balls are optimized based on many users' experiences and are for references only. Minor adjustment may be necessary in terms of the nature of milling materials, total volume of material and balls, required fineness, and other factors for your applications.

3. How to clean jars and balls after ball milling process?

In some ball milling process, the milled materials may stick to the grinding jars and balls during the long time grinding process. Following please refer to a few methods which may help.

1). To clean with a ultrasonic cleaning machine. Depending on the milled materials, DI water, Acetone, and IPA may be used sequentially or alone. 

2). To ball mill with the right solvent. After discharge the milled materials, add some solvent the grinding jars and rotate the milling jars with the balls for two to three minutes. Remove solution and Check. Repeat the process if necessary. 

3). To ball mill with harder materials. After discharge the milled materials, add some hard materials into the milling jars and rotate the milling jars with the balls for two to three minutes. Open grinding jars and Check. Repeat the process if necessary. 

For cleaning agate balls, you may consider to use quartz sand, unstained glass such as some window glass or container glass. 

4. How to ball mill in vacuum or inert gas atmosphere using the PBM-04 and stainless steel jacket

The planetary ball mill PBM-04 can be used to for vacuum ball milling and inert gas atmosphere ball milling for sensitive materials when stainless steel jacket is used together with the selected grinding jars. The SS jacket is equipped with two shut off valves connecting to vacuum pump and inert gas bottle. The following pictures show the set up and one stainless steel jacket with a grinding jar.

5. How to maintain the PBM-04 ball mill?

The PBM Series planetary ball mill series do not need regular grease lubrication because of the self-lubricating gears, so users saves time in operation. The self-lubricating gears also eliminated risk of gear damage due to failing to maintenance regularly.

However, the ball milling area does need to be kept clean. After each use, the milling area must be cleaned properly from any dirt or loose materials. For cleaning the grinding jars and balls, add some water and detergent into the grinding jars then rotate the jars with balls for a few minutes.  Refer to item 3 for more detail about cleaning jars and balls after ball milling process. 

5) What is ratio of grinding ball to feed material?

Generally the ration of grinding ball to feed material is between 1:1.1 to 1:1.5. Maximum load of each grinding jar is 2/3 of its normal volume
