The ball mill tank is a configuration component of the planetary ball mill, which can be used to load grinding balls and samples to achieve sample grinding in a sealed environment.
Depending on the type of sample and grinding conditions, the planetary ball mill can be equipped with different types of ball grinding tanks to cope with different grinding situations.
The ball grinding tanks commonly used in planetary ball mills can be divided according to material and functionality:
In terms of materials, there are mainly zirconia, alumina, agate, stainless steel, tungsten carbide, etc.
In terms of functionality, there are mainly conventional ball milling tanks and vacuum ball milling tanks.
Below I will choose to focus on briefly introducing to you:
1. Zirconia ball mill tank
The zirconia ball mill tank has high hardness, high density, wear resistance and impact resistance, good toughness, is not easy to break, and will not cause contamination to the sample. It is a very high-standard ball mill tank among planetary ball mills and can be used for grinding almost all samples. Therefore, the price of the jar is relatively high, and it is suitable for customers with sufficient budget and high experimental requirements.
2. Agate ball mill jar
Agate ball mill jars are also commonly used because agate has strong corrosion resistance, resistance to strong acids and alkalis, and wear resistance. More importantly, it does not cause metal contamination to the sample. It is an ideal ball mill jar material, especially In the grinding experiment for detecting heavy metals in soil samples, the agate ball mill tank is the national standard choice.
One disadvantage of agate ball mill jars is that they are easily broken. We can equip the outside of your agate ball mill jar with a stainless steel sheath to prevent the jar from being dropped to the ground and broken.
3. Stainless steel ball mill tank
The stainless steel ball mill tank is one of the commonly used ball mill tanks, and many samples can be configured and used. There is a layer of chromium-rich oxide film (passivation film) on the internal surface of the stainless steel ball mill tank, which has certain rust resistance and acid resistance. However, under the high-speed movement of the planetary ball mill, some metal impurities in the stainless steel ball mill tank will be mixed into the sample. , it is not recommended for grinding experiments that require high sample contamination.
4. Vacuum ball mill tank
Vacuum ball mill jars are suitable for grinding flammable, explosive and easily oxidized samples, as well as samples that need to be isolated from the air. The lid of the vacuum ball mill jar is equipped with an air inlet and exhaust valve. After the sample is installed and the jar lid is closed, a vacuum pump can be used to extract the air in the jar. Vacuum ball mill tanks are generally made of stainless steel. If the sample is also required to be free of metal contamination, the inner wall of the tank can also be lined with agate, zirconia, etc.
