At present, most of the existing artificial sand production lines adopt the wet production process. No matter what type of sand washing machine is used, the major disadvantage is that the fine sand (particles below 0.16mm) is seriously lost, and some even lose 20% and more. This not only loses output, but also seriously affects the gradation of sand, resulting in unreasonable gradation and coarse fineness modulus, which greatly reduces the product quality of machine-made sand.
The fine sand recycling machine is used in the wet sand production line. It can make the produced sand meet the nation standards and completely solve the problems of excessive water content, excessive humidity, large mud content, more dust and more impurities the sand .it belongs to a new type of environmental protection sand washing equipment.
The fine sand recycling machine is used in the wet sand production line. It always works together with the sand washing machine, which combines the advantages of sand washing machine and de-watering screen,which give consideration to both functions of sand washing and sand and stone material dehydration. It can make the produced sand meet the nation standards.
The loss of fine sand can be reduced to within 5-10%
It solves the problems of high fineness modulus of finished sand and low stone powder content in artificial aggregate processing system.
2. Vibrating screen adopts polyurethane screen
Polyurethane screen has longer life than other types of screen, and is not easy to block holes.
3. Cyclone lined with polyurethane
The service life of the whole device is improved, and the work of slurry concentration and liquid clarification can be successfully completed.
4. Fine sand is fully recovered
It can recover 85% of the fine particle materials in the total discharge, which has technical and economic advantages incomparable with other equipment. At the same time, the workload of the sedimentation tank is reduced, and the cleaning cost of the sedimentation tank is reduced.
Structure of fine sand recycling system: It consists of motor, slurry pump, cyclone, linear vibrating screen, cleaning tank, return box, etc.
Work process: The sand-water mixture is transported to the cyclone, and the fine sand concentrated by centrifugal classification is provided to the vibrating screen through the grit chamber. After being dehydrated by the vibrating screen, the fine sand and water are separated, and a small amount of fine sand and mud are 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 discharge port, so as to complete the three functions of cleaning, dehydration and classification. The weight concentration of the recovered material from the linear vibrating screen is 70%-85%. The fineness modulus can be adjusted by changing the pump speed, changing the mortar concentration, adjusting the overflow water volume, and replacing the sand nozzle.
