There are different Ball milling jars of planetary ball mill. According to material and functionality, In terms of material, there are mainly stainless steel, agate, corundum, tungsten carbide, nylon, zirconia, polytetrafluoroethylene, polyurethane, etc.;

In terms of functionality, the main There are conventional ball milling jars, vacuum ball milling jars, temperature-controlled ball milling jars, etc.

1. Stainless steel ball mill tank

Stainless steel ball milling jar is one of the commonly used ball milling jars, and many samples can be configured and used. There is a layer of chromium-rich oxide film (passive film) on the inner surface of the stainless steel ball mill tank, which has certain rust resistance and acid resistance, but under the high-speed motion of the planetary ball mill, some metal impurities in the stainless steel ball mill tank will be mixed into the sample , if the grinding experiment requires high sample contamination, it is not recommended to use it.

2. Agate ball mill jar

Agate material ball milling jars are also commonly used ball milling jars, because agate has strong corrosion resistance, strong acid and alkali resistance, and wear resistance. More importantly, it will not cause metal pollution to samples, so it is an ideal material for ball milling jars, especially In the grinding experiment aimed at the detection of heavy metals in soil samples, the agate ball mill jar is the choice of the national standard.

The disadvantage of agate ball milling machine jars is that they are easily broken, so the outside of the agate ball milling jars are equipped with stainless steel sheaths to prevent the jars from falling on the ground and breaking them.

3. Zirconia ball mill tank

The zirconia ball mill jar has high hardness, high density, wear resistance and impact resistance, good toughness, is not easy to break, and will not pollute the sample. It is a ball mill jar with a very high specification in the planetary ball mill machine, and it is suitable for grinding almost all samples ore. However, the price of the milling jar is relatively high, and it is suitable for customers with sufficient budget and high requirements for experiments.

4. Vacuum ball mill tank

The vacuum ball mill jar is suitable for grinding flammable, explosive and oxidizable samples, as well as samples that need to be isolated from the air. The tank cover of the vacuum ball mill tank is equipped with an air intake valve, which can be used to extract the air in the tank with a vacuum pump after the sample is filled and the tank cover is closed. The vacuum ball mill tank is generally made of stainless steel. If the sample is required to be free from metal contamination, linings such as polytetrafluoroethylene, agate, and zirconia can also be nested on the inner wall of the tank.

5. Temperature-controlled ball mill tank

The temperature-controlled ball mill jar is a special ball mill jar developed for the temperature-controlled planetary ball mill. There is an interlayer in the middle of the jar, which is similar to a vacuum insulation cup. When the equipment is working, a cooling medium can be introduced into the interlayer to take away the heat generated during grinding. , zero loss in the internal circulation of the refrigerant, suitable for samples that require temperature-controlled grinding.
