Description

Technical Field

[0001] This utility model relates to the field of talc separation technology, specifically a talc beneficiation device that achieves efficient separation of talc from associated minerals based on frictional differences. Background Technology

[0002] Current talc beneficiation methods mainly rely on the principle of friction, using drum / belt separators, or on the principle of color, employing color sorters / manual separation. These methods have the following drawbacks: Complex structure: Mechanical equipment is expensive to manufacture and difficult to maintain; Low energy efficiency: Color sorters require a continuous power supply, resulting in high energy consumption; High cost: Manual sorting is labor-intensive and inefficient.

[0003] Therefore, there is an urgent need for a talc beneficiation device with a simple structure and no power consumption. Utility Model Content

[0004] To address the problems of complex structure and high energy consumption in existing talc beneficiation devices, this invention provides an energy-saving talc separation device that achieves efficient separation of talc and associated minerals based on frictional differences.

[0005] This utility model relates to a talc beneficiation device, which mainly includes a sorting plate, a material distribution trough, and a side plate; The sorting plate consists of an upper sorting plate and a lower sorting plate, which are movably connected. The sorting plate is a flat plate with an angle A of 25-45° to the vertical line; The sorting plate is a curved plate, and its curve can be an arc, a parabola or other curved shape. The curve length S of the curved plate and the angle B between the tangent at the exit and the horizontal line are 5-45°. Let the particle size of the material be D, where D is greater than or equal to 20 mm. The relationship between the curve length S and the angle B between the tangent at the outlet and the horizontal line is as follows: When the size of D is fixed, S and B are inversely proportional, that is, the longer S is, the smaller the angle B is. When the length of S is fixed, D is directly proportional to B, that is, the larger D is, the larger the included angle B is. The material distribution trough includes a stone trough located near the outlet of the lower sorting plate and a talc trough located at the far end. The side plate is attached to the left and right sides of the upper and lower sorting plates. A round hole is opened on the side plate at the connection between the upper and lower sorting plates. A first arc-shaped elongated hole and a second arc-shaped elongated hole are opened on the upper and lower parts of the side plate respectively according to the adjustment angle of the upper and lower sorting plates, which are used to adjust the tilt angle of the upper and lower sorting plates.

[0006] The side plate also serves to fix the position of the upper and lower sorting plates and prevent materials from falling off.

[0007] Furthermore, the width of the sorting plate is 200-500mm; The sorting plate is a curved plate with a curve length S = 100-350 mm; The mixed stone trough and the talc trough are located at a distance of 300-600mm horizontally and 300-500mm vertically from the lower plate outlet.

[0008] Furthermore, connecting plates with mounting holes are respectively provided on the back of the upper and lower sorting plates and at the locations corresponding to the first and second arc-shaped elongated holes of the side plates. The connecting plates are close to the side plates, and the mounting holes are respectively aligned with the first and second arc-shaped elongated holes. The upper and lower adjusting screws are respectively matched and fitted into the mounting holes and fixed with bolts for fixing after the angle of the upper and lower sorting plates is adjusted.

[0009] Furthermore, the central angles corresponding to the first and second arc-shaped elongated holes are both 0-45°, and these central angles are determined by taking the circular holes on the side plate corresponding to the connection between the upper and lower sorting plates as the center.

[0010] Furthermore, the sorting plate is made of stainless steel or other metal materials.

[0011] Furthermore, the upper sorting plate overlaps the lower sorting plate by 3-5mm and is connected by a hinge or hinge.

[0012] Furthermore, the upper and lower sorting plates are connected by hinges. Two blades of the hinge are welded to the upper and lower sorting plates respectively. A 3-5mm spacer is placed between the hinge and the upper sorting plate. The hinge's shaft is a long screw, one end of which passes through a round hole in the side plate and is secured with a bolt cap. The spacer serves as a space for adjustment of the upper and lower sorting plates.

[0013] Furthermore, the device also includes a feeder with its outlet aligned with the top of the sorting plate.

[0014] The working principle of this talc beneficiation device is as follows: Talc and impurities have different frictional forces. When they fall onto the upper sorting plate at the same angle and initial velocity, they move along the sorting plate under the action of gravity and finally fly out in a parabolic trajectory from the lower sorting plate. Due to the difference in friction, the talc flies farther, while the impurities fly closer. Therefore, the separation of talc and impurities can be achieved simply by placing a material distribution trough diagonally below the lower sorting plate.

[0015] The method for separating talc using the talc beneficiation device of this utility model includes the following steps: The material is initially screened, and the angles of the upper and lower sorting plates are adjusted according to the particle size of the material. After preliminary screening, the talc ore with relatively uniform particle size and moist surface is evenly fed to the upper sorting plate by a feeder. As the material slides down the sorting plate, it flies out in a parabolic trajectory. Separate the talc and miscellaneous stones according to the distance they fly out.

[0016] The advantages of this utility model talc beneficiation device compared with existing devices are as follows: 1. Extremely simple structure: Only sorting plate, material trough and side plate are needed, reducing installation space by more than 30%; 2. Zero energy consumption: It sorts objects purely using friction, requiring no electricity; 3. Low cost: The material cost is only 10%-15% of that of a drum-type mineral concentrator.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings, but this is not intended to limit the present invention. Example

[0020] A talc beneficiation device, referring to Figure 1 It mainly includes a sorting plate 1, a material trough 2 and a side plate 3; the sorting plate 1 is composed of an upper sorting plate 1-1 and a lower sorting plate 1-2, both of which are made of 304 stainless steel. The upper sorting plate 1-1 overlaps the lower sorting plate 1-2 by 3-5mm and is connected by a hinge 4. The upper sorting plate 1-1 is a flat plate with a width of 200-500mm, and the angle A between it and the vertical line is 25-40°. The sorting plates 1-2 are curved plates, and their curves can be arcs, parabolas or other curved shapes. In this embodiment, they are arc-shaped, with an arc length S (S=100-350mm) and an angle B between the tangent at the exit and the horizontal line of 5-45°. Let the particle size of the material be D, where D is greater than or equal to 20 mm. The relationship between the curve length S and the angle B between the tangent at the outlet and the horizontal line is as follows: When the size of D is fixed, S and B are inversely proportional, that is, the longer S is, the smaller the angle B is. When the length of S is fixed, D is directly proportional to B, that is, the larger D is, the larger the included angle B is. The material distribution trough 2 includes a stone trough 2-1 located near the outlet of the lower sorting plate 1-2 and a talc trough 2-2 located at the far end, and is set at a distance of 300-600mm horizontally and 300-500mm vertically from the outlet of the lower sorting plate 1-2; the specific position of the stone trough 2-1 is determined according to the simulated stone movement trajectory 9, and the specific position of the talc trough 2-2 is determined according to the simulated talc movement trajectory 10; Side plate 3 is attached to the left and right sides of the upper sorting plate 1-1 and the lower sorting plate 1-2. A round hole (not shown in the figure) is opened on the side plate 3 at the connection between the upper sorting plate 1-1 and the lower sorting plate 1-2. A first arc-shaped long hole 3-1 and a second arc-shaped long hole 3-2 are opened on the upper and lower parts of the side plate 3 respectively according to the adjustment angle of the upper sorting plate 1-1 and the lower sorting plate 1-2, which are used to adjust the tilt angle of the upper sorting plate 1-1 and the lower sorting plate 1-2.

[0021] On the back of the upper sorting plate 1-1 and the lower sorting plate 1-2, and at the locations corresponding to the first arc-shaped elongated hole 3-1 and the second arc-shaped elongated hole 3-2 of the side plate 3, a connecting plate with mounting holes (not shown in the figure) is respectively provided. The connecting plate is close to the side plate 3, and the mounting holes are respectively aligned with the first arc-shaped elongated hole 3-1 and the second arc-shaped elongated hole 3-2. The upper adjusting screw 6 and the lower adjusting screw 7 are respectively matched and fitted into the mounting holes and fixed with bolts for fixing after the angle of the upper sorting plate 1-1 and the lower sorting plate 1-2 is adjusted.

[0022] The two blades of the hinge 4 are welded to the upper sorting plate 1-1 and the lower sorting plate 1-2 respectively. A 3-5mm pad 8 is set between the hinge 4 and the upper sorting plate 1-1. The shaft of the hinge 4 is a long screw, one end of which passes through the round hole on the side plate 3 and is fixed with a bolt.

[0023] Reference Figure 2 The central angle C corresponding to the first arc-shaped long hole 3-1 and the central angle d corresponding to the second arc-shaped long hole 3-2 are both 0-45°. The central angle is determined by the circular hole (not shown in the figure) opened at the connection between the upper sorting plate 1-1 and the lower sorting plate 1-2 on the side plate 3.

[0024] Example 2: For materials with a diameter of 20-30mm, the upper sorting plate is 300mm wide and the angle between the upper sorting plate and the vertical line is 33°. The sorting plate is an arc-shaped plate with a radius of 150mm, an arc length of S=235mm, and an included angle of B=28°. The waste stone trough and the talc trough are set at a distance of 480mm horizontally and 440mm vertically from the outlet of the sorting lower plate.

[0025] Mineral processing results: The ore content of the raw ore was 45.0%, the ore content of the mixed stones after separation was 6.4%, and the ore content of the concentrate was 76.9%.

[0026] Example 3: For materials with a diameter of 30-40mm, the upper sorting plate is 300mm wide and the angle between the upper sorting plate and the vertical line is 41°. The sorting plate is an arc-shaped plate with a radius of 150mm, an arc length of S=235mm, and an included angle of B=33°. The waste stone trough and the talc trough are set at a distance of 410mm horizontally and 440mm vertically from the outlet of the sorting lower plate.

[0027] Mineral processing results: The ore content of the raw ore was 54.7%, the ore content of the sorted mixed stones was 5.2%, and the ore content of the concentrate was 92.1%.

[0028] Through Examples 2 and 3, it can be found that the larger the particle size of the material, the better the effect. At the same time, the lower the mineral content in the mixed stone, the lower the mineral content in the talc trough, and the lower the separation rate.
