When the planetary ball mill is running, the grinding balls in the ball mill tank will undergo high-frequency collisions and strong friction, generating a large amount of heat and affecting the sample.
In order to protect the properties of the sample, it is often necessary to control the upper temperature limit to reduce the impact on the sample. Samples are affected.
In order to keep the planetary ball mill running at low temperature, certain methods need to be used.
The following are two commonly used cooling methods for planetary ball mills.
1. Pre-freezing the ball mill jar
Since the sample is ground in a ball mill tank, we can pre-freeze the ball mill tank before grinding. For example, place the ball mill tank in a liquid nitrogen environment to cool down, and then load the sample for grinding, so that the ball mill tank can be controlled to a certain temperature. within the temperature range.
2. Pass refrigerant gas through the working part to create a low-temperature environment
The working part of the planetary ball mill is a large wheel that rotates with four ball milling tanks. We can cover the working part with a cooling cover, and then pass the refrigerant gas (such as liquid nitrogen) into the cooling cover to make the ball milling tanks rotate. In a continuously low temperature environment.
Since the temperature around the ball mill tank is low, the heat generated in the tank will slowly dissipate, thereby achieving the cooling effect inside the tank.
Using liquid nitrogen for cooling, the temperature can be controlled between -60° to -1°. This is very helpful for laboratory use.
We Hunan Kingda Ceramic Technology Co., Ltd. can customize the cooling gas delivery pipes for our ball mills to help you achieve the cooling effect.
