Automated recirculation system for large particle size analysis

A recirculation system for coarse particle size analysis in a wet-type particle size analyzer, in which a liquid supply pump for supplying liquid from a liquid supply tank to a mixer is provided,

• a discharge port connected with a side of a recirculation pump and discharging a mixture liquid mixed with particles in the mixer is provided,
• a pipe line connected with the other side of the recirculation pump is branched and coupled to a liquid supply line connected to the supply pump, a recirculation line for discharging the mixture liquid to the mixer, a first analysis line connected with a side of a particle size analyzer and a discharge line for discharging the mixture liquid to an outside of the recirculation system, and
• a second analysis line connected with another side of the particle size analyzer and discharging from the particle size analyzer to the mixer,
• the recirculation line and the second analysis line discharging the mixture liquid to an upper inputting part,
• wherein two rotatable baffles are attached to both side walls of the mixer, one baffle is rotated by a flow velocity of the mixture discharged from the recirculation line and the other baffle is rotated by a flow velocity of the mixture discharged from the second analysis line, and rotation directions of the two baffles are opposite each other.
