The appearance of the laboratory planetary ball mill has solved many grinding problems. It far exceeds the traditional ball mill in terms of grinding efficiency, grinding particle size, energy consumption reduction, and application range. It has become the first choice for ultrafine grinding of samples.

So what is the structure of the planetary ball mill, and why is the grinding effect better? Next, let's explore the structure of the planetary ball mill and re-understand the planetary ball mill machine.

Let's first take a look at the internal structure of the planetary ball mill. There is a circular main wheel that rotates at high speed on the horizontal plane at the bottom of the working area. Four tank seats are evenly distributed around the wheel. shaft, and a detachable ball mill jar is placed inside the jar seat, and grinding media and samples are placed inside the ball mill jar.

The working principle of the planetary ball mill: the operation of the planetary ball mill is similar to the operation between the stars and the planets. When the equipment is working, the main wheel rotates in one direction at high speed, while the shaft inside the tank seat rotates in the opposite direction, and the two directions rotate in opposite directions. At the same time, the force of the ball mill is superimposed on the ball mill jar, and the energy obtained by the grinding medium inside the ball mill jar is very large. At this time, the grinding medium that has obtained energy impacts, squeezes and rubs the sample, and the grinding of the sample can be completed.

If the rotation speed of the main wheel and the rotation of the ball mill jar increases, the force will increase, the grinding energy will increase, and the sample may be ground more finely. Therefore, the rotation speed is an important factor to consider the performance of the planetary ball mill.

Compared with the traditional lab ball mill, the planetary ball mill has other advantages, such as small size and low noise, in addition to the increased force, improved grinding effect and efficiency.

The ball milling jar of the planetary ball mill can be disassembled, so you can replace the ball milling jar and grinding balls of various materials according to the characteristics of the sample, such as agate, zirconia, corundum, nylon, etc. Vacuum or inert gas-filled ball mill jars increase the applicable range of sample grinding.

The planetary ball mill can drive four ball mill jars for grinding at one time, and can obtain four samples at the same time or grind four different samples.

The above is a brief introduction to the operation structure and working principle of the planetary ball mill. In today's laboratories, the planetary ball mill has gradually replaced the roller ball mill for fine grinding and ultrafine grinding of samples. It is recommended that qualified laboratories can carry out configuration.
