Description
Advantages and Characteristics
• The fine sand recovery device can effectively reduce the loss of fine sand and control it within 5 ~ 10%. The problems in artificial material processing system are well solved which includes the fineness modulus of finished sand is high and the content of stone powder is low.
•The synthetic plastic used for dewatering screen, sieve plate, and spray head is developed by our factory together with several polymer research units, through repeated experiments, the life span of the material is 5-6 times longer than that of steel plate. It is wear-resistant and difficult to block holes.
• Fine sand recovery system can recover fine grain material up to 90% of the total emission. There are unparalleled technical and economic advantages over other equipment.
•The fine particles are fully recovered, which reduces the workload of the sedimentation tank, the cost of clearing tank also been reduced.
•Fine sand recovery system reduces the natural storage time of fine materials that can be directly transported to the market.
•Design, refit and applied to more fields such as commercial concrete companies, wharf sand absorption, and other industries according to the different requirements from the users.
Equipment Principle
The equipment consists of a motor, wear-resistant pump, mortar concentrator, cleaning tank of straight-line dehydration screen, reverse box, and so on.
Working process: the mud water flows into the cleaning tank, through the wear-resistant pump, and arrive at the mortar concentrator, separate the sewage and sand by the concentrator, and the sand passes through the spray head and come to the dehydration screen, arrive into the conveyor belt after dehydration. The sewage returns to the reverse box, split flows into the cleaning tank, and the excess part leaks out.
Hydrocyclone Structure:The top of the hydrocyclone is a hollow cylinder. The lower part of the hydrocyclone is an inverted cone connected to the cylinder
The two parts constitute the working simplified body of the hydrocyclone. The top part of the cylinder body is tangentially fitted with an ore feed pipe, with an overflow pipe and an overflow conduit at the top. There is a sand sink at the bottom of the conical cylinder. All parts are connected with flanges and screws. Feed ports, cylinders, and sand sinks are usually lined with rubber, polyurethane, silicon carbide or diabase cast stones to reduce wear and replace after wear.
Operational Principle
A strong centrifugal force is used to separate the mixture under high-speed rotation.
The classic static hydrocyclone, for example, uses external pressure to push the feed mixture into the cyclone at a greater speed, because the mixture moves along the tangential direction of the cyclone, which causes the liquid to rotate along the wall of the cylinder. This motion is generally referred to as the outer swirl.
The particles in the external swirl are subjected to centrifugal force. If the density of the particle is greater than the density of the surrounding liquid, it will get more and more centrifugal force. Once the centrifugal force is greater than the liquid resistance caused by the movement, the particles will overcome this resistance and move in the direction of the wall of the device and separate from the surrounding liquid.
The particles near the wall of the device are driven by the liquid above the cyclone and move downward along the wall of the cyclone. The particles near the bottom flow port gather together to form a suspension with high consistency, which is discharged from the bottom flow port.
After separation, the liquid rotates downward, and after entering the cone, the inner diameter of the liquid separator decreases gradually, and the speed of the liquid rotation accelerates.
Because of the uneven distribution of pressure along the radial direction when the eddy current is generated, the smaller the axis is, the closer to the axis it approaches to zero and becomes a low-pressure region or even a vacuum region, which leads to the liquid moving towards the axis direction.
The closer to the axis, the smaller the place is.
When arriving at the axis, it approaches to zero becomes a low-pressure region or even a vacuum region, which causes the liquid to move toward the axis.
At the same time, due to the large reduction of the bottom flow port of the cyclone separator, the liquid cannot be rapidly discharged from the bottom flow port, and the overflow port in the center of the top cover of the swirl cavity moves part of the liquid toward it because it is in the low-pressure area, thus forming an upward rotational motion and discharging from the overflow port.
Hydrocyclone is mainly used in mineral processing:
1 Heavy-medium cyclone is the common heavy-medium separation equipment.
2 As grading equipment in grinding circuit, especially as grading equipment for fine grinding.
3. Desliming and concentrating ore pulp.
