Background technology of overflow classification powder:
With the rapid development of new materials science, silicon carbide is becoming more and more important The quality requirement of micro powder is higher and higher, especially in high quality silicon carbide In the production of micro powder, the coarse and fine silicon carbide micro powder is very important Particle classification is the most important and difficult part of technology.
The principle is that the settling velocity of different particle sizes is different.That is to say, by adjusting the feed water speed and changing the sinking speed of the micro powder, the micro powder will flow out from the diversion tank when the feed water speed exceeds the falling speed of the micro powder. The larger the micro powder particles are, the faster the falling speed is, and the smaller the particles are, the slower the falling speed is.When the rising speed of water level is greater than the settling speed of micro powder particles, these particles overflow from the overflow tank. The detection workers observe through the microscope and classify according to the daily standard.
