[0002] Laterite nickel ore is an important mineral resource, primarily containing nickel, iron, aluminum, and silicon. It is widely used in stainless steel production and the chemical industry. To overcome the limitations of traditional mineral processing methods, the ore-dressing shaker, a highly efficient gravity separation device, has been widely used in the separation of laterite nickel ore. Through the combined effects of gravity and water flow, it effectively separates minerals of varying densities.

[0003] However, when processing laterite nickel ore, existing mineral processing shaking tables usually adopt a single-shaped bed bar design, and the grooves formed between the bed bars are also of the same shape. The single-shaped groove design is difficult to take into account the separation of minerals with different particle sizes and densities, resulting in low separation efficiency.

[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] In order to solve the technical problem that a single-shaped groove design is difficult to take into account the separation of minerals of different particle sizes and densities, resulting in low separation efficiency, the present application provides a mineral separation shaking table that can achieve the purpose of improving the efficiency and accuracy of mineral separation.

[0030] It should be noted that the mineral processing shaking table described in this application is used for but not limited to the mineral processing of laterite nickel ore. For the convenience of explanation, in this application, only the mineral processing shaking table is used for the mineral processing of laterite nickel ore as an example. The principle of applying the mineral processing shaking table to the mineral processing of other types of minerals is essentially the same as that applied to the mineral processing of laterite nickel ore, and will not be described in detail here.

[0031] See also Figure 1-3The present application provides a mineral processing shaking table, comprising a shaking table body 1, a first bed bar 2 and a second bed bar 3, the shaking table body 1 has a shaking table surface 11, and a water supply trough 12 and an ore supply trough 13 are arranged on the front side of the shaking table surface 11, the water supply trough 12 supplies water to the shaking table surface 11, and the ore supply trough 13 supplies slurry to the shaking table surface 11, wherein the shaking table surface 11 is divided into a U-shaped groove portion 101 and a V-shaped groove portion 103 from front to back, and one side of the water supply trough 12 and the ore supply trough 13 is the front side of the shaking table surface 11, and the water flow direction is perpendicular to the length direction of the trough body and flows from front to back; arc depressions are provided on both sides of the first bed bar 2, and the first bed bar 2 is arranged at equal distances from front to back and is arranged on the U-shaped groove portion 101, and a U-shaped groove 201 is formed between two adjacent first bed bars 2, and the two side walls of the U-shaped groove are smooth curves. The bottom is smooth, and the movement of particles in the groove is smoother, which reduces the possibility of particles getting stuck. The side walls of the U-shaped groove are relatively flat, and particles are more likely to move with the water flow during movement rather than being deposited at the bottom of the groove for sorting fine particles with higher density; both sides of the second bed strips 3 are inclined, and the second bed strips 3 are arranged equidistantly from front to back in the V-shaped groove portion 103, and a V-shaped groove 301 is formed between two adjacent second bed strips 3. The bottom of the V-shaped groove is sharp, and the two side walls are inclined straight walls, which makes it easier for particles to slide or roll along the two sides of the groove during movement. Heavier particles are more likely to settle to the bottom of the groove due to the greater gravity. After the U-shaped groove 201 first sorts the fine particles with higher density, the problem of particles getting stuck in the V-shaped groove 301 is reduced. That is, U-shaped grooves 201 are used in the front section of the shaking table to process fine-grained minerals, reduce the stuck situation of particles, and improve the uniform distribution of water flow. V-shaped grooves are used in the back section of the shaking table to process medium-grained minerals, help heavier particles to settle, improve the stratification effect, and increase the recovery rate of useful minerals.

[0032] In one embodiment, see Figure 2 and Figure 3A mixing groove portion 102 is further provided between the U-shaped groove portion 101 and the V-shaped groove portion 103 on the rocking bed surface 11. A plurality of the first bed bars 2 are arranged at equal intervals to form a first mixing groove group 1021, and a plurality of the second bed bars 3 are arranged at equal intervals to form a second mixing groove group 1022. The second mixing groove group 1022 and the first mixing groove group 1021 are alternately arranged on the mixing groove portion 102 from front to back, that is, the U-shaped groove portion 101 is followed by a second mixing groove group 1022 composed of the second bed bars 3, and then connected to a second mixing groove group 1022 composed of the first bed bars 2. The first mixing trough group 1021 is composed of a distribution of U-shaped grooves, V-shaped grooves and then U-shaped grooves. The effect is that the U-shaped grooves are used to process fine particles with higher density first, and then the heavier particles are deposited at the V-shaped grooves. Finally, the missed fine particles with higher density are processed through a part of the U-shaped grooves. As a result, the mixing trough portion 102 can comprehensively have both U-shaped grooves and V-shaped grooves in the same area, which can adapt to minerals of different particle sizes, while maintaining a uniform distribution of water flow, and further sorting and recovering useful minerals of medium particle size through the mixed grooves.

[0033] In one embodiment, see Figure 4 In order to improve the control effect of the movement trajectory of fine particles with higher density in the U-shaped groove portion 101, the height of the first bed strip 2 on the U-shaped groove portion 101 increases successively from front to back, thereby forming the effect of intercepting fine particles with higher density in turn, which helps to increase the probability of fine particles migrating laterally along the length direction of the U-shaped groove.

[0034] In one embodiment, see Figure 3 To improve the efficiency of V-shaped trough 103 in processing coarse-grained minerals, a third bed strip 4 is included. One side of each strip is vertical, and the other side is inclined. Two third bed strips 4 form a group, with their vertical surfaces facing each other, forming a vertical wall trough 401. These vertical wall troughs 401 are inserted into V-shaped trough 103 and are used to process coarse-grained minerals at the rear end of the shaking table. The trough with vertical walls helps heavier particles settle, while lighter particles are carried away by the water flow, ultimately separating useful minerals from the coarse-grained minerals.

[0035] Furthermore, the height of the third bed strip 4 is greater than the height of the second bed strip 3 , thereby forming an interception effect and reducing the probability of heavier particles passing over the third bed strip 4 .

[0036] In one embodiment, see Figure 1 and Figure 2One end of the U-shaped groove portion 101, the mixing groove portion 102 and the V-shaped groove portion 103 are flush, and the lengths of the U-shaped groove portion 101, the mixing groove portion 102 and the V-shaped groove portion 103 decrease from front to back, forming a triangular empty area 104 at the tail end of the shaking table surface 11, and the triangular empty area 104 and the shaking table surface 11 are transitioned by a gentle slope and raised in height. As the height gradually increases, the water flow speed and direction will change, which helps heavier minerals to settle at the bottom and flow to the concentrate end.

[0037] In one embodiment, see Figure 1 and Figure 2 The rocking bed body 1 includes a support frame 14 and a rocking mechanism 15. The support frame 14 is arranged at the bottom of the rocking bed surface 11 and is used to support the rocking bed surface 11. The movable end of the rocking mechanism 15 is connected to the rocking bed surface 11 and is used to rock the rocking bed surface 11. The support frame 14 is supported at the bottom of the rocking bed surface 11 and provides the rocking bed surface 11 with freedom of rocking. The rocking mechanism 15 can adopt the existing cam lever type bedside transmission, or other bedside transmission mechanisms with the function of rocking the rocking bed surface 11. This is not limited here.

[0038] It should be noted that the support frame 14 and the rocking mechanism 15 are both mature components of existing rocking tables, and will not be described in detail here.

[0039] In one embodiment, see Figure 1 and Figure 2 The support frame 14 is provided with a plurality of guide hoppers 16 for classifying and guiding the minerals. The number of the guide hoppers 16 and the corresponding installation positions are selected according to the actual degree of sorting.

[0040] Furthermore, in order to improve the uniformity of water output, water outlets are arranged at equal intervals at the bottom of the water supply trough 12.

[0041] Furthermore, in order to control the water flow in sections, a flow valve is provided on the water outlet.

[0042] In order to better understand this application, the following Figures 1 to 5 The technical solution of the present application is described in detail: U-shaped grooves 201 are used in the front section of the shaking table to process fine-grained minerals, reduce the possibility of particle jamming, and improve the uniform distribution of water flow; in the middle section of the shaking table, a mixed trough body of U-shaped grooves 201 and V-shaped grooves 301 is used to process medium-grained minerals; in the rear section of the shaking table, a mixed trough body of V-shaped grooves 301 and vertical wall grooves 401 is used to process large-grained minerals, help the sedimentation of heavier particles, improve the stratification effect, and increase the recovery rate of useful minerals.

[0043] The specific implementation methods of the present application described above do not limit the scope of protection of the present application. Any other corresponding changes and modifications made based on the technical concept of the present application should be included in the scope of protection of the claims of the present application.
