1. what is the desander？
Desander is a piece of drilling rig equipment designed to separate sand from the drilling fluid. Abrasive solids which cannot be removed by shakers can be removed by it. The desander is installed before but after shakers and degasser.
2. What is the purpose of the desander？
Desander and purification equipment is a kind of pile foundation auxiliary equipment mainly used for grooving foundation construction, drilling foundation construction and trenchless foundation construction machinery. Desander is mainly applicable to the purification and recovery of mud in pile foundation works, cut-off wall works, slurry balance shield construction and slurry pipe jacking construction with slurry wall protection and circulating drilling technology. Reducing construction cost and improving construction efficiency are necessary equipment for foundation construction.
3. What are the advantages of the desander?
a. It can effectively control the sand content and particle accuracy of the mud during construction, separate the solid particles from the liquid, and dewater and discharge the separated waste residue.
b. The equipment is helpful to improve the hole forming rate of pile foundation, reduce the cost of slurry during construction, and realize the recycling of construction slurry.
c. The closed circulation mode of slurry and low moisture content of slag are beneficial to reduce environmental pollution.
d. The effective separation of particle is beneficial to the improvement of pore making efficiency
e. The full purification of slurry is conducive to controlling the performance of slurry, reducing sticking and improving the quality of pore making.
