It is widely used in rock crushing and washing plant, crushed sand or natural sand washing plant, mineral tailings processing site, etc. As we know, currents and washing machine wheel bucket type or screw spiral type can’t process fines below 3mm, that’s why we produce this system.
• SUPL Sand recycling system has absorbed foreign advanced technology, and designed combined with sand field actual situation. It is widely used in mud purification, artificial Sand production line, hydropower station, sand aggregate system, glass raw material Processing system, coarse slime recovery, and recycle fine material, It can effectively reduce the loss amount of fine material; solve problems of end product such as relatively high fineness modulus and relatively low stone powder content. The fine material can be recycled as high as 95%, with incomparable technical and economic advantages.

Working Principle:

• Through rubber pipes sand water mixture is extracted from cleaning tank into slurry pump. The fine sand is collected by the centrifugal force of the cyclone, then fed to the polyurethane screen from the apex spray. The 0.16-3mm fine sand and water are efficiently separated through the vibration screen. The waste water will flow back, through weld chute or pipes flowing to a settling pond.

Technology Advantages:

• Recycling 0.16-3mm fine sand
• Recycling rate reaches above 95%.
• The water content of final sand is within 12%-15 %.
• Effectively reduce the loss of fine sand, solve the problem of sedimentation tank accumulates.

A hydrocyclone is most often used to separate "heavies" from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where "lights" are the greater part of the mixture and where the "heavies" settle fairly easily. Generally, hydrocyclones are used in continuous flow systems so that the instantaneous liquid inflow to the hydrocyclone is equal to the total instantaneous outflow of "lights" plus "heavies". In cases where "heavies" are a very small part of the whole liquid, it is sometimes advantageous to accumulate them in the bottom of the hydrocyclone for batch wise removal.

Applications include:

• In pulp and paper mills to remove sand, staples, plastic particles and other contaminants.
• In the drilling industry to separate sand from the expensive clay that is used for lubrication during the drilling.
• In industry to separate oil from water or vice versa.
• In metal working to separate metal particles from cooling liquid.
• In potato processing plants to recover starch from waste water.
• In mineral processing, hydrocyclones are used extensively both to classify particles for recirculation in grinding circuits and to differentiate between the economic mineral and gangue.
• To remove sand and silt particles from irrigation water for drip irrigation purposes.
• Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous stream.
• A high speed rotating (air)flow is established within a cylindrical or conical container called a cyclone. Air flows in a helical pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream, and strike the outside wall, then falling to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone, the rotational radius of the stream is reduced, thus separating smaller and smaller particles. The cyclone geometry, together with flow rate, defines the cut point of the cyclone. This is the size of particle that will be removed from the stream with a 50% efficiency. Particles larger than the cut point will be removed with a greater efficiency, and smaller particles with a lower efficiency.

An alternative cyclone design uses a secondary air flow within the cyclone to keep the collected particles from striking the walls, to protect them from abrasion. The primary air flow containing the particulates enters from the bottom of the cyclone and is forced into spiral rotation by stationary spinner vanes. The secondary air flow enters from the top of the cyclone and moves downward toward the bottom, intercepting the particulate from the primary air. The secondary air flow also allows the collector to optionally be mounted horizontally, because it pushes the particulate toward the collection area, and does not rely solely on gravity to perform this function.

A Centrifuge Separation Separators is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities. A hydrocyclone will normally have a cylindrical section at the top where liquid is being fed tangentially, and a conical base. The angle, and hence length of the conical section, plays a role in determining operating characteristics. A hydrocyclone has two exits on the axis. the smaller on the bottom (underflow or reject) and a larger at the top (overflow or accept). The underflow is generally the denser or coarser fraction, while the overflow is the lighter or finer fraction. Internally, centrifugal force is countered by the resistance of the liquid, with the effect that larger or denser particles are transported to the wall for eventual exit at the reject side with a limited amount of liquid, while the finer, or less dense particles, remain in the liquid and exit at the overflow side through a tube extending slightly into the body of the cyclone at the center. Forward hydrocyclones remove particles that are denser than the surrounding fluid, while reverse hydrocyclones remove particles that are less dense than the surrounding fluid. In a reverse hydrocyclone the overflow is at the apex and the underflow at the base.

 

There are also parallel-flow hydrocyclones where both the accept and reject are removed at the apex. Parallel-flow hydrocyclones remove particles that are lighter than the surrounding fluid. In a suspension of particles with the same density, a relatively sharp cut can be made. The size at which the particles separate is a function of cyclone diameter, exit dimensions, feed pressure and the relative characteristics of the particles and the liquid. Efficiency of separation is a function of the solids' concentration. the higher the concentration, the lower the efficiency of separation. There is also a significant difference in suspension density between the base exit (fines) and the apex exit, where there is little liquid flow. If the size range of the particles is limited, but there are differences in density between types of particles, the denser particles will exit preferentially at the apex. The device is therefore a means of selective concentration of, for example, minerals. This device is also related to the centrifuge; both of them are intended to separate heavies and lights in liquid by application of centrifugal force.
