[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0030] In order to solve the technical problem that the design of a single shape of groove is difficult to consider the separation of minerals of different particle sizes and densities, resulting in low separation efficiency, the present application provides a mineral separation shaking table, which can achieve the purpose of improving the efficiency and precision of mineral separation.

[0031] It should be noted that the mineral separation shaking table described in the present application is used for but not limited to the mineral separation of laterite nickel ore. In order to facilitate the description, in the present application, only the mineral separation shaking table applied to the mineral separation of laterite nickel ore is taken as an example for description, and the principle of the mineral separation shaking table applied to the mineral separation of other types of minerals is substantially the same as that applied to the mineral separation of laterite nickel ore, which will not be described here.

[0032] Referring to Figures 1-3, the application provides a mineral separation table, comprising a table body 1, a first bed bar 2 and a second bed bar 3, the table body 1 is provided with a table surface 11, the front side of the table surface 11 is provided with a water supply groove 12 and a mineral supply groove 13, the water supply groove 12 supplies water to the table surface 11, and the mineral supply groove 13 supplies ore pulp to the table surface 11, wherein the table surface 11 is sequentially divided into a U-shaped groove part 101 and a V-shaped groove part 103 from front to back, the water supply groove 12 and the mineral supply groove 13 are on one side of the front side of the table surface 11, the water flow direction is perpendicular to the length direction of the groove body, and the flow direction is from front to back; the first bed bar 2 is provided with a circular arc recess on both sides, and the first bed bar 2 is arranged in the U-shaped groove part 101 at equal intervals from front to back, and a U-shaped groove 201 is formed between two adjacent first bed bars 2, the side walls of the U-shaped groove are smooth curves, and the bottom is smooth, the movement of particles in the groove is more smooth, and the situation of particles being stuck is reduced, the side walls of the U-shaped groove are relatively gentle, and particles are more likely to move with the water flow when moving rather than depositing at the bottom of the groove, which is used for separating fine particles with large separation density; the second bed bar 3 is provided with a slope on both sides, and the second bed bar 3 is arranged in the V-shaped groove part 103 at equal intervals from front to back, and a V-shaped groove 301 is formed between two adjacent second bed bars 3, the bottom of the V-shaped groove is sharp, and the side walls are inclined straight walls, which makes particles more likely to slide or roll along the two sides of the groove during movement, and heavier particles are more likely to settle at the bottom of the groove due to greater gravity, which reduces the problem of particles being stuck in the V-shaped groove 301 after the U-shaped groove 201 separates fine particles with large separation density. That is, the U-shaped groove 201 is used to process fine-grained minerals in the front section of the table, which reduces the situation of particles being stuck and improves the uniform distribution of water flow, and the V-shaped groove is used to process medium-grained minerals in the rear section of the table, which helps heavy particles to deposit, improves the separation effect, and improves the recovery rate of useful minerals.

[0033] In one embodiment, referring to FIG. 2 and FIG. 3, a mixing groove 102 is further provided between the U-shaped groove 101 and the V-shaped groove 103 on the shaking table bed surface 11. A plurality of first bed strips 2 are arranged equidistantly to form a first mixing groove group 1021, and a plurality of second bed strips 3 are arranged equidistantly to form a second mixing groove group 1022. The second mixing groove group 1022 and the first mixing groove group 1021 are alternately arranged from front to back in the mixing groove 102, i.e. the U-shaped groove 101 is followed by a second mixing groove group 1022 composed of second bed strips 3, and then connected to a first mixing groove group 1021 composed of first bed strips 2, forming a distribution of U-shaped groove, V-shaped groove and U-shaped groove again. The effect is that the U-shaped groove is used to process fine particles with large density first, then the V-shaped groove is used to deposit heavy particles, and then the U-shaped groove is used to process the fine particles with large density that are missed, so that the mixing groove 102 can have both U-shaped groove and V-shaped groove in the same area, which can adapt to minerals of different particle sizes, while maintaining uniform distribution of water flow, and further sorting and recovering useful minerals of medium particle size through the mixed groove.

[0034] In one embodiment, referring to FIG. 4, in order to improve the control effect of the movement trajectory of fine particles with large density in the U-shaped groove 101, the height of the first bed strip 2 in the U-shaped groove 101 is gradually increased from front to back, forming an effect of intercepting fine particles with large density in sequence, which helps to improve the probability of transverse migration of fine particles along the length direction of the U-shaped groove.

[0035] In one embodiment, referring to FIG. 3, in order to improve the efficiency of processing coarse-grained minerals in the V-shaped groove 103, a third bed strip 4 is further included. One side of the third bed strip 4 is a vertical surface, and the other side is an inclined surface. Two third bed strips 4 form a group with their vertical surfaces opposite to each other, forming a vertical wall groove 401. The vertical wall groove 401 is inserted into the V-shaped groove 103 for processing coarse-grained minerals in the rear section of the shaking table. The groove with vertical wall helps the heavy particles to deposit, while the light particles are carried away by the water flow to finally separate the useful minerals in the coarse-grained minerals.

[0036] Further, the height of the third bed strip 4 is greater than the height of the second bed strip 3, thereby forming an intercepting effect to reduce the probability of heavy particles passing over the third bed strip 4.

[0037] In one of the embodiments, referring to FIG. 1 and FIG. 2, the U-shaped groove part 101, the mixing groove part 102 and the V-shaped groove part 103 are flush at one end, and the lengths of the U-shaped groove part 101, the mixing groove part 102 and the V-shaped groove part 103 decrease from front to back, forming a triangular empty area 104 at the tail end of the shaking table bed surface 11, and the triangular empty area 104 and the shaking table bed surface 11 are connected through a gentle slope transition and a height lifting. With the gradual increase of the height, the water flow speed and direction change, which helps the heavier minerals to deposit at the bottom and flow to the concentrate end.

[0038] In one of the embodiments, referring to FIG. 1 and FIG. 2, the shaking table body 1 includes a support frame body 14 and a shaking mechanism 15. The support frame body 14 is arranged at the bottom of the shaking table bed surface 11 for supporting the shaking table bed surface 11. The movable end of the shaking mechanism 15 is connected with the shaking table bed surface 11 for shaking the shaking table bed surface 11. The support frame body 14 supports at the bottom of the shaking table bed surface 11 and provides the freedom degree of shaking of the shaking table bed surface 11. The shaking mechanism 15 can adopt the existing cam lever type bed head transmission, or other bed head transmission mechanism with the function of shaking the shaking table bed surface 11, which is not limited here.

[0039] It should be noted that the support frame body 14 and the shaking mechanism 15 are mature components of the existing shaking table, which will not be described in detail here.

[0040] In one of the embodiments, referring to FIG. 1 and FIG. 2, a plurality of flow guide hoppers 16 are arranged on the support frame body 14 for the classification and flow guide of the minerals. The number of the flow guide hoppers 16 and the corresponding installation positions are selected according to the actual separation degree.

[0041] Further, in order to improve the uniformity of the water outlet, a plurality of water outlets are arranged at the bottom of the water supply groove 12.

[0042] Further, in order to control the water flow in sections, a flow valve is arranged on the water outlet.

[0043] In order to better understand the present application, the technical solutions of the present application are described in detail as follows in combination with FIG. 1 to FIG. 5: the U-shaped groove 201 is used in the front section of the shaking table to process fine-grained minerals, reduce the situation of particle jamming, and improve the uniform distribution of water flow; the U-shaped groove 201 and the V-shaped groove 301 are used in the middle section of the shaking table to process medium-grained minerals; the V-shaped groove 301 and the vertical wall groove 401 are used in the rear section of the shaking table to process large-grained minerals, help the heavy particles to deposit, improve the layering effect, and improve the recovery rate of useful minerals.

[0044] The specific implementation of the present application described above does not constitute a limitation on the protection scope of the present application. Any various other corresponding changes and modifications made according to the technical concept of the present application shall be included in the protection scope of the claims of the present application.
