Desander

Desander is a kind of Slurry Separation System. It is a necessary equipment of foundation construction,
used for pile foundation projects adopting slurry hole/tunnel wall supporting, rotary drilling rig,
circular drilling technology; Diaphragm wall project and slurry purification recycling of slurry pipe-jacking construction,
with the features of reducing construction cost,reduce environmental pollution and increasing construction efficiency

 1. vibratory motor 2. dewatering shale 3. storage tanks 4. cyclone feeder pump 5. cyclone units 6. spigot 7. coarse screen 8. cyclone overflow        
 9. holding tank    10. automatic level control

Separation Process:

1. Slurry with soil particles from feeding pump goes through the coarse screen (7) and into the storage tank (3), with solids more than 2mm separated. 

2. The fluid in the storage tank(3) is pumped into the cyclones (5), with solids more than 0.06mm discharged on the dewatering screen (2),
and the cleaned fluid is discharged via the cyclone overflow（8） and into the holding tank (9).

3. The automatic level control (10) is to keep the water level in the tank(3) to prevent the feeder pump (4) from running without load or low load
