Fine sand recovery, dewatering screen

Dewatering Screens, Fine Sand Recovery Machine

1. Structure: Composed of motor, sand pump, cyclone, TS linear dewatering screen, cleaning tank, and return material box, etc.

2. Process: The pump transfers the sand-water mixture to the centrifugal separator. The finely graded sand, after centrifugal concentration, is supplied to the vibrating screen through the sand outlet. After dehydration by the vibrating screen, the sand and water are separated. A small amount of fine sand and mud is returned to the cleaning tank via the return bin. When the liquid level in the cleaning tank is too high, it is discharged through the discharge outlet. The straight dehydration screen recovers a material weight concentration of 70% to 85%. Adjusting the fineness modulus can be achieved by changing the sand pump speed, adjusting the砂浆 consistency, regulating the overflow water volume, and replacing the sand outlet. This completes the three functions of cleaning, dehydration, and classification.

3. Performance Features:

In traditional manual sand processing, the spiral sand washing machine is used for washing mud and dewatering, resulting in almost uncontrollable loss of fine sand in the artificial sand. With this fine sand recovery system, the loss of fine sand can be reduced to between 5% and 10%, effectively solving the problem of high fineness modulus and low stone powder content in the finished sand of artificial aggregate processing systems.

(2) The vibration screen features a polyurethane mesh that offers a longer lifespan than other types of screens and does not clog the holes.

(3) The cyclone liner is made of polyurethane, enhancing the overall lifespan of the unit and enabling smooth operations such as slurry concentration and liquid clarification.

(4) Recycles 85% of the fine particulate matter from total emissions, boasting unparalleled technological and economic advantages compared to other equipment.

(5) Fine particles are fully recycled, reducing the workload of the sedimentation pond and lowering the cleaning costs.

(6) Reduced material stacking time, allowing for direct transit and supply to the market.

(7) Solutions can be tailored to meet various customer requirements.

4. Product Features:

High operating frequency, strong vibration intensity, low moisture content in the screen-over products, and high unit processing capacity.

(2) The power source utilizes a vibration motor without bearings or couplings, featuring a simple structure and easy installation and maintenance. It has a low maintenance cost and can operate continuously for 24 hours.

(3) The pre-dewatering sieve plate surface is installed at a 45-degree angle to the horizontal, with the dewatering sieve plate having a negative inclination. This design increases the dewatering area and facilitates the rapid dewatering of material to form a filter layer.

(4) The side panels, crossbeams, motor mounts, and reinforcing plates are all connected with G-type tension-torque bolts, which are seamless to prevent cracking issues caused by welding stress.

(5) The screen plate is made of imported polyurethane material, featuring high hole rate, good permeability, and long service life.

(6) The small sieve machine utilizes rubber springs for vibration reduction, ensuring low noise and effective damping. It significantly reduces the dynamic load on the foundation of the sieve machine. Large sieve machines are equipped with manganese steel springs, which offer good elasticity and a long service life.

(7) The side panels are made of high-quality boiler steel plate, with excellent welding properties and good resistance to wet H2S stress corrosion.

(8) The whole machine design utilizes finite element structural analysis software to ensure the sieve frame's strength, rigidity, and rational load distribution, while also being lightweight and reducing energy consumption.
