Working structure and principle of fine sand recovery machine: 

1. Structure: it is composed of motor, slurry pump, cyclone ZKR linear vibrating screen, cleaning tank, return box, etc. 

two。. Working process: the pump transports the sand-water mixture to the hydrocyclone, the centrifugally concentrated fine sand is provided to the vibrating screen through the sand settling nozzle, after dewatering by the vibrating screen, the fine sand and water are separated, and a small amount of fine sand and mud is returned to the cleaning tank through the return box, when the liquid level of the cleaning tank is too high, it is discharged through the outlet.The weight concentration of the material recovered by the linear vibrating screen is 70% and 85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar attempt, adjusting the overflow water volume and changing the sand nozzle.
