The present invention relates to a specific gravity separation beneficiary that separates and selects heavy metals, precious metals or heavy sands from natural sands or abrasive sands, and more particularly, screwes natural sands or artificial mineral sands transported from Bucket conveyers with water. Passing through the conveyor conveys the gangue (large particle), etc. to the outside, and flows only the mineral sand mixed with minerals to the bottom and drops to the cylindrical rotary separator, and between the spiral protrusions formed inside the cylinder of the rotary separator. The mineral sand, which is located at the valley of the spiral projection, is separated by the water supplied to the valley between the spiral projections when it is returned by the rotation of the rotary centrifuge cylinder which is rotated opposite to the spiral direction of the spiral projection. When flowing down and moved to the lower position, gangue is floated together with water, A rotary specific gravity separation fan that can be discharged to the outside of the tip side and the minerals are accumulated without flowing down to the bottom of the spiral protrusion, and then moved back along the valley and collected through the catch port at the rear end to maximize the beneficiation effect of the effective mineral. It is about.

Conventional specific gravity separation beneficiaries are described in Japanese Patent Nos. 41235 and 41412.

Their technology allows the mineral sand to flow along the comb or arched stone with water, causing sand to rise and heavy minerals to collide with the stone so that they cannot be lowered and collected through both collection tanks, separated by spraying while falling. A beneficiation separator that is to be collected separately by raising the conveyor nonwoven fabric, and they simply supply natural death and water to the stone and flowing groove of the inclined beneficiation plate to separate minerals and sand by the purpose of being separated or floated by specific gravity. The purpose is to collect minerals in the raising of the nonwoven fabric, but the separation and inaccuracy due to the flow of water are inaccurate, and the floating gangue and sand are stuck in the stone and the flow is obstructed. The drawback was a low inefficiency beneficiation yield.

The present invention is to solve the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a natural sand or artificially formed mineral sand supplied through a screw conveyor with water in the bone between the spiral projection formed inside the cylinder of the rotary separator. When it flows, the mineral and gangue are rotated with the rotation of the cylinder, and when they are raised in the clockwise direction from the bottom position, they separate the tangled minerals and gangue due to the water jet of the nozzle which is located in each valley and sprays water. Due to the repetitive action that the minerals and gangue are gathered by the movement and separation at the same time as the lower part of the cylinder is moved and separated simultaneously by the force, the gangue flows to the tip by the inclined inclination angle while being floated together with the water, and the minerals are discharged to the outside. When the mineral is accumulated in the valley of the ball and the accumulated mineral is higher than the height of the thread, It is moved toward the rear end by reverse rotation of the screw thread formed in the direction opposed to the station by the rear end through the cylindrical collection to jipsugu to provide a separate rotary rocker portion that can easily obtain a high mineral.

Hereinafter, with reference to the accompanying drawings will be described the structure and effect of the specific gravity separation beneficiary of the present invention.

In FIG. 1, the rotary specific gravity splitting machine of the present invention supplies natural sand or artificial sand to the screw conveyor 2 from the bucket conveyor 1, and water to the natural sand or artificial sand supplied to the screw conveyor 2 When the mixture is moved together with the rotation of the screw while the large gangue stone is discharged to the outside, the mineral sand is dropped to the guide plate (3), (4) through the wire mesh 21 of the lower, guide plate (4) The mineral sand supplied through) is fed into the cylinder 6 of the rotary separator 5.

The method of supplying the mineral sand by the bucket kit conveyor 1 and the screw conveyor 2 is one of a widely used transfer method, and alternatively, the mineral sand may be supplied in a state in which minerals can be separated through a grinder.

The rotary separator (5) is open at one side and the water collecting port (51) at the other end is formed at the bottom, the guide plate (4) is fitted to the case 52 and the guide rollers 71 on both sides and the rotary roller (7) in the center Is rotated in contact with the outside when the nozzle (6) is inclined to approximately 40 °-45 ° inclined in the cylinder (6) and a plurality of nozzles installed on the support (8) one end fixed to the case (52) ( 92 consists of a water tank 9 having a distributor 93 for supplying water.

In addition, the inside of the cylinder 6 has a semi-circular protrusion shape having a diameter of 10φ-20φ to form a spiral protrusion 61 and a valley 62 so as to have a female screw shape from the front end 63 to the rear end 64. On the surface of the spiral protrusion 61 is formed by coating with urethane paint or silicon 65 and a plurality of nozzles 92 to spray water to the location of the keel 62 as shown in FIG.

In addition, the motor 72 is coupled to the rotary roller 7 for rotating the cylinder 6, the water tank (9) to the water supply valve 93 and the distributor 91 to adjust the amount of water supplied to a plurality of nozzles 92 A plurality of drain valve 94 is to be connected to each.

And the mineral collected by the collecting port 51 is collected in the sump (53), the gangue discharged to the tip (63) of the cylinder (6) is transported and processed through the discharge conveyor (11).

Next, the effect of the present invention will be described.

In FIG. 1, when the mineral sand separately supplied through the bucket kit conveyor 1 and the screw conveyor 2 is supplied with water through the wire mesh 21 and through the guide plates 3 and 4, FIG. As can be accumulated between the spiral projection 61 and the valley 62 of the cylinder (6) through both ends of the guide plate (4) and at the same time rotated by the motor 72 and the rotary roller (7) When the mineral sand is raised clockwise to the lower position by the water sprayed through each nozzle 92 connected to the water tank 99 and the distributor 91 to remove the mineral and gangue tangled in each bone (62) This is to separate the minerals and gangue in each bone (62) by the collision due to the repeated action of the force of the water flowing down and the rotational motion of the cylinder (6).

Due to the weight of the separated minerals, they accumulate in the valleys 62 at the lower end of the cylinder 6, and the gangue is lifted up by the water and flows to the tip 63 by the inclined slope and is discharged to the discharge conveyor 11.

On the other hand, when the minerals accumulated in the valleys 62 are higher than the height of the spiral protrusion 61, the minerals are moved to the rear end 64 by the reverse rotation of the spiral protrusion 61 formed in the reverse direction of the rotation direction of the cylinder 6, and the rear end 64 Minerals dropped and dropped from the) is collected in the sump container 53 through the water collecting port 51, and the minerals at this time obtain only high-quality minerals.

Therefore, the mineral processing machine of the present invention separates tangled minerals and gangue by spraying water while repeating the movement of the minerals and gangue by rotation through each valley of the spiral protrusion formed opposite to the rotational direction of the cylinder, and the minerals move inversely. It collects high quality minerals from the rear end of the cylinder and floats the gangue to the end of the cylinder.The structure is simple and the separation of minerals and gangue is easy. It will be possible.
