Linear Dewatering Screen for Sand Grading/Fine Sand Recovery Equipment

Fine sand recovery equipment can be used for ceramic raw materials processing system of dehydration step,concentrator tailings recycling,quartz sand processing system,hydropower station sand and gravel processing system and so on.Jinyang fine sand recovery equipment can effectivly solve the sand and fine material recycling.

The existing artificial sand production line currently,mostly adpots wet production process,no matter what form of sand washing machine,the biggest drawback is fine sand(smaller than 0.16MM)lost seriousely.even lost more than 25%.This is not only a serious loss but also seruousely affect the sand gradation,resulting in unreasonable gradation,fineness modulus of coarse,greatly reducing the quality of the product of the mechanism of sand.Too much fine sand emissions but also cause enviromental pollution.

In order to slove the above problems,Jinyang company has successfully developed a fine sand recycling device effectively solve the problem of fine sand recovery.

Fine sand recovery equipment working principle
1 structure:a motor,sand pump,centrifugal separator(hydrocyclone). linear dewatering screen,cleaning tank,recycle boxes and other components,
2 working process:
Pumped sand water mixture is delivered to centrifugal separator.after centrifuge classification,concentrated fine sand discharged by underflow spigot into the dewatering screen,After the vibration sieve dewatering, fine sand and water separation, a small amount of fine sand, mud and so on return to the tank and then return to the cleaning 
tank, while the cleaning tank level is too high, discharged through the discharge port.

Linear dewatering screen recyclables by weight concentration of 70% -85%. The fineness modulus can be adjusted by changing the pump speed, changing mortar try,adjusting the overflow of water and replacing the undderflow exit.So as to complete the cleaning, dehydration and grading of three kinds of functions.

Fine sand recovery device can decompose water sand mixture reasonably, realize the sand recycling project. can recycle 95% fine particles of the total slurry,fine sand recovery equipment with unparalleled technical and economic advantages.

Case
One company in laizhou shandong province plans to make construction sand with gold 
tailings,capacity 300t/d,ordered Jinyang fine sand recovery equipment.its sand density is 
25%,after processed by fine sand recovery machine(hydrocyclone+dewatering screen),they get the sand with moisture below 18%,which can meet the requiement for construction sand.
