Click to chat· The closed circuit system is the opposite of the open circuit system. The closed-circuit system can reduce the phenomenon of over-grinding at the same time the output material can lose part of the heat after conveying and grading. When the coarse powder is returned to grinding the temperature in the mill can be reduced which is beneficial
Click to chat· From the grinding chamber the powder is pulled through a cyclone and drops into a sifting device. The sifting device eliminates only a very small coarse fraction of ground powder. This coarse material can be re-introduced into the grinding process to optimize the yield. General-purpose powder formulas can be sifted through 80- to 120-mesh screens.
