Planetary Ball Mill 4x500ml | Lubrication Free, Two-year Warranty, Inert gas & Vacuum Compatible

Planetary Ball Mill 4x500ml | Lubrication Free, Two-year Warranty, Inert gas & Vacuum Compatible


General Introduction - ON PROMOTION (For 110V machine only)

PBM-2L (4X500mL) planetary ball mill is a compact and easy-to-use laboratory planetary ball mill for mixing, homogenizing,  fine grinding, mechanical alloying, cell disruption,  small sample preparing, new product development and small volume high-tech material production.  The systems features small volume, high efficiency, low noise and quick clamp. When using vacuum jars, samples can be processed in a vacuum or inert gas environment. The system can be used to smash and blend various products of different materials and granularity with dry or wet methods. The PBM-2L is widely applied in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Medicine, Environmental Protection etc. Free samples testing services may be provided upon request.

Working Principle

The PBM-2 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.
