Titanium sand grinding machine, also known as titanium dioxide powder grinder, is a machine used in the titanium dioxide industry for grinding and crushing titanium dioxide particles into fine powder. The working principle of the machine is as follows:

1. Material feeding: Titanium dioxide particles are fed into the grinding chamber of the machine from the feeding hopper.
2. Grinding: The grinding chamber contains a rotor with a series of blades that rotate at high speed. As the blades rotate, they impact and crush the titanium dioxide particles against the interior walls of the grinding chamber, reducing them to a fine powder.
3. Classification: The ground titanium dioxide powder is then classified by a classifier located above the grinding chamber. The classifier separates the fine powder from the coarse particles, ensuring that only the desired particle size is collected.
4. Collection: The fine powder is collected in a collection chamber located below the grinding chamber. The collected powder can then be further processed or packaged for use in various applications.

Overall, the working principle of the titanium sand grinding machine involves the grinding and crushing of titanium dioxide particles using a rotor with blades that rotate at high speed. The resulting fine powder is then classified and collected for use in various applications in the titanium dioxide industry.
