Abstract

The present invention is a beneficiation machine for sorting metal (gold, silver, etc.) or heavy sand from natural sand or sand grit (sand crushed natural stone).

First, the natural sedimentation rate by sedimentation method is obtained by the following Stockes equation.

v = g (p ₂ -p _One ) D ² ÷ 18μ

v: sedimentation velocity (m / s)

g: acceleration of gravity (m / s ² )

p ₂ : density of particles (Kg / ㎥)

p ₁ : density of liquid (water) (Kg / ㎥)

μ: Viscosity coefficient of liquid (water) (Kg / m.s)

D: diameter of particle (m)

For weighted objects, the settling velocity that falls in the air or in the water depends on the density.

Therefore, the beneficiation characteristics of the present invention are applied to the fact that the sedimentation rate is more different in water when two materials having different densities are heavier than water and have the same particles.

The reason for this is that the difference between the specific gravity of sand specific gravity 2.0 and iron specific gravity 7.85 is 1: 3.92, but in water, the specific gravity in water is 1.0: iron minus 1.85, iron is 1.85 minus the specific gravity of water. 6.85.

In other words, the difference in specific gravity in water is greater than that in air.

Since sand and iron have a specific gravity difference of 1: 6.85, the speed of falling in water is also proportionally different, and sand and iron can be separated using the falling time, provided that the sand and iron particles are the same. Should be similar.

In the above, sand and iron are compared, but gold and sand, which have a high specific gravity, are more advantageous in the separation process due to the larger difference in specific gravity.

Invented based on the principles described above, the present invention was designed to extract metals (gold, silver, etc.) or heavy sand from natural sand and mawangwang sand to promote commercialization according to their respective uses.

The present invention consists of six components, as shown in the representative figure, and the names of the components are yarn supply tank (A), primary and secondary particle sorting device (B), tertiary particle sorting device (C), metal ( Gold, silver) separation tank (D), exit (sand discharged) conveyor (E), metal (gold, silver, etc.) collection tank (F).

Description

Specific Gravity Optometry {Specific Gravity Ore Separator}

The purpose of the present invention is to replace the depleted mining industry by efficiently collecting natural resources such as gold, silver, and gold, and to use a wide range of indifferent resources.

The present invention is a mining machine technology, and it is called a beneficiation machine that selects gold, silver, heavy sand, etc. from natural or mawangwang sand.

In the process of sorting minerals, many people have tried to reduce the loss rate and easily select a large amount easily and accurately, but it is still a problem in terms of time and quantity.

Conventional specific gravity separators select the minerals to be collected through a system such as a curved bottom surface or a grass filter, as shown in FIG. 1, thereby reducing the effectiveness of the screening by friction and supplying natural sand to the mineral processing equipment. In order to supply through the use pipe, it must be collected by floating sand in the water, so the metal, which has a high specific gravity to collect in the water, sinks to the bottom, and only the particles with low specific gravity are sucked in. What had not been the cause of the deterioration of the utility value of the machinery.

In addition, this supply method had to be adopted because the processing capacity of the beneficiator was relatively insufficient, so it was not possible to supply it to the bucket conveyor or excavator so that the capacity of the beneficiator could not be increased. It is not possible to increase the capacity without limit.

In other words, it was a method of filtering primary impurities (gravel, monarch, etc.) and other foreign substances in the water and supplying them to the optometry, but did not obtain the effect as described above.

This method is also a problem that is not easy to work in the desert or where water is scarce.

Therefore, a large amount of water must be supplied by a separate method, so there are many problems in practical use.

The technical problem to be achieved by the present invention is that unlike the conventional method described above, natural sand or mawang gwang sand is directly supplied to the baget conveyor or excavator, so that the productivity is increased by increasing the collection rate, cost reduction and high value added is the technical problem will be.

In order to sort the particles by the same size, the supplied natural sand or marangsan sand is adopted by installing several sizes of screens with different sizes of screen holes in stages. At the same time as the horizontal movement, the sorting is performed for each particle to be collected, and these particles are settled into the sorting tank of the specific gravity separation process, and unnecessary particles of the sorted particles are discharged out by the rotating screw.

The screens also make it easy to remove and attach stainless meshes made of holes that match the size of the particles to be obtained, even when they need to be replaced due to wear.

Vibrators were installed in the primary and secondary particle separators because vibrations were applied for the process of uniformly obtaining the sorted particles into the sorting tank and the process of shaking off the particles stuck to the screen.

In the next process, the water stored in the sorting tank and the auxiliary tank is circulated in a constant direction through a water channel installed in the sorting tank using a circulating pump (the path through which the water flows), and the particles are transported by the flow of water so that a high specific gravity ( Gold, silver, etc.) and sedimentary sand first settle and fall into the collection tank, and low-density sand or foreign matter falls further and accumulates in the sorting tank hopper and is discharged out of the conveyor.

On the other hand, the sorting product collection tank is demountable and detachable. During operation, the valve in the upper part is opened so that the sorting recovered product enters the tank by natural drop and when the collection is done, the valve is locked and the tank is released to remove the water in the sorting tank. It is designed so that it does not have to be removed so that it can be used even in places where there is not much water.

3 is a diagram illustrating a process of separating natural yarns or abrasive sands (hereinafter referred to as yarns) for each particle, and are transported and processed in the direction of the arrow.

First of all, the particles should be sorted by the size of the metal or heavy yarn to be obtained. In this process, the mesh is made of stainless steel and the screw is installed inside to rotate the filter to move horizontally. This made it possible.

In this case, the yarn supplied from the yarn supply hopper (1) is supplied by the yarn supply conveyor (2) into the primary separation screen (5), and the primary separated particles passing through the screen hole therein It will fall to the secondary separation screen (3).

In the primary separation screen (5), large particles of gravel, royal dust, and foreign matters that do not pass through the holes are pushed out by the rotation of the primary separation screw (6) and discharged to the outside through the discharge chute (11).

On the other hand, the secondary separation screen (3) is denser than the primary separation screen (5), and the primary separated particles pass through the holes of the secondary separation screen (3) and are separated into secondary and primary conveying conveyors (7). Particles transported to the furnace and not passed through the holes are pushed out by the rotation of the secondary separation screw 4 and configured to be discharged to the outside through the discharge chute 11.

Here, the yarn feed conveyor (2), the primary separation screw (6), the secondary separation screw (4), the primary separation screen (5), and the secondary separation screen (3) have their respective axes to achieve the respective processes simultaneously. After connecting with a joint, one geared motor rotates, speed is controlled, and the amount of processing is kept constant.

The secondary separated particles are pushed out by the rotation of the primary conveying conveyor 7 and enter the tertiary separation screen 8.

The tertiary separation screen (8) consists of a hole of the particle size to be collected, and the secondary separated particles transported there are separated into tertiary through this hole and dropped to the secondary conveying conveyor (10) to supply tertiary particles. Is sent to sphere (13).

Particles that do not pass through the holes of the tertiary separation screen 8 are transferred to the secondary particle feed port 12 by a tertiary separation screw 9 and here again the primary conveying conveyor 7 to achieve the respective processes simultaneously. The tertiary separation screen (8) and the tertiary separation screw (9) are connected to one geared motor after connecting the respective shaft joints, so that the rotation and control the speed is configured to maintain a constant amount of processing.

4 is a view illustrating a process of sorting particles separated by sizes by specific gravity difference, wherein the third separated particles falling from the tertiary particle supply port 13 are to a tertiary particle supply chute 15 having an inclination of about 10 degrees. Due to the vibration of the vibrator 25, a certain amount of particles are settled in a channel (a passage through which water flows) installed in the sorting tank 16.

The sorting tank 16 is designed to the size of the required processing capacity and the structure is as follows.

In order to generate convection (24) at a constant flow rate of water, the channel is installed by blocking the circumference of the elliptical tank so that the flow can be maintained smoothly without being affected by the water in the center of the circular tank.

Meanwhile, the sorting tank 16 and the auxiliary tank 31 are configured to be connected so that the water is forced to circulate using the circulation pump 32, and the most important settling distance in the process of sorting by specific gravity difference is to be adjusted to the flow rate. The overdrain 26 was installed to adjust the valve 33 and maintain the same water level at all times and prevent overflow.

Since a certain amount of the third separated particles falling down from the tertiary particle supply chute 15 and settled according to the specific gravity are different depending on the specific gravity of the water, the metal (gold, silver, etc.) having a high specific gravity does not move much distance. It does not settle and enters the primary collection tank (28), and the metal + heavy sand (20) having a lower specific gravity is moved a little more and settles and enters the secondary collection tank (27). Foreign substances (22) and other foreign substances are moved to a long distance and settled past the collection tanks (27), (28) to accumulate along the inclined surface of the sorting tank hopper (30), and thus accumulated retirement discharge It is discharged out by the conveyor 18.

The secondary particle supply chute 14 is located on the opposite side of the tertiary particle supply chute 15, and the collection tank is also installed symmetrically so that the secondary separated particles are the same as the process of the third separated particles.

Final sorted metal (gold, silver, etc.) (19) and metal + heavy sand (20) is stacked into the primary and secondary collection tanks (27), (28), whereby the valve (29) and flange (Flange) Since it is connected, the valve 29 is locked at the time of collection, and then the flanges of the collection tanks 27 and 28 are released and separated to collect the final target metals (gold, silver, etc.) and heavy sand.

The effect obtained by the present invention can improve productivity by supplementing the disadvantages of the conventional method described above, so that it can be exported to a country that can collect a lot of gold dust, mine gold, etc., and can earn foreign currency. The biggest effect is that it can contribute to improving the country's trade balance.

It can handle the amount of work (30 tons of sand per hour on average) that was not possible with conventional gold dusting methods (the amount of work can be raised or lowered depending on the size of the machine). As human beings use resources that are of little interest as they can be harvested within, they can be seen as the effect of the present invention.

Claims (1)

It is a beneficiator that beneficiates natural sand or grinding sand by specific velocity using the speed and distance difference by specific gravity. Therefore, the particles selected by size through the screen are fixed by vibration of the vibrator 25. The sediment is sedimented in the channel of the sorting tank 16 at high speed, and the particles having a high specific gravity are sedimented in the collection tanks 27 and 28 according to the flow rate of the water forcedly circulated by the circulation pump 32. These low particles are moved and settled farther than the collection tank, and are stacked in the sorting tank hopper 30 and discharged out by the discharge conveyor 18, so that the sand and minerals can be separated.
