Description

Technical Field

[0001] This invention relates to the field of mineral gravity separation equipment technology, specifically to a novel shaking table device suitable for separating fine-particle and micro-fine-particle non-ferrous metal minerals. Background Technology

[0002] In the field of industrial mineral gravity separation, the 6S shaking table and the Yunnan Tin shaking table are currently the mainstream traditional gravity separation shaking table equipment. Both types of equipment rely on an eccentric connecting rod structure to drive the bed surface to complete reciprocating asymmetrical motion, and combine the bed surface slope and flushing water flow to achieve mineral separation. They are widely used in non-ferrous metal ore gravity separation operations. However, long-term field application has shown that traditional shaking table equipment has several inherent technical defects and is difficult to adapt to the current separation needs of fine-grained and micro-fine-grained difficult-to-separate non-ferrous metal ores.

[0003] First, the sorting adaptability is poor. Traditional shaking tables rely on eccentric connecting rods to achieve intermittent impact drive. The pushing force and motion stroke of the bed surface cannot accurately match the sorting requirements of fine and micro-fine non-ferrous metal mineral particles. Micro-fine mineral particles are easily lost with the water flow under the impact vibration of the equipment and the scouring effect of the water flow, resulting in poor metal mineral retention and inability to achieve efficient stratified sorting.

[0004] Secondly, the equipment installation layout is limited. The drive motor of a traditional shaking table has a single fixed installation structure, which can only be fixed in one position. It cannot be adjusted according to the size of the mineral processing workshop and the layout of supporting equipment, resulting in low flexibility in the layout of equipment in the plant and poor adaptability to the renovation of old workshops.

[0005] Secondly, the slope adjustment adaptability is poor. The traditional shaking table has a fixed bed slope. After manually adjusting the bed slope, the height of the feed end and discharge end from the ground cannot be adjusted synchronously. It is necessary to modify the feed chute, ore receiving pipeline and other supporting facilities on site. The modification process is complicated, the workload is large and the commissioning cycle is long.

[0006] Finally, the mineral recovery rate is low. In the case of fine-grained non-ferrous metal ore beneficiation, the impact motion characteristics of traditional shaking tables are prone to causing the loss of valuable metal fine particles, resulting in a significant shortcoming in metal recovery rate, low mineral resource utilization, and a substantial increase in the production cost of mineral processing, which restricts the efficient development and utilization of fine-grained disseminated non-ferrous metal ores. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing traditional shaking table equipment, such as poor sorting adaptability, limited installation layout, lack of height adaptation for slope adjustment, and low recovery rate of fine-grained minerals. It provides a new type of shaking table device to achieve efficient sorting of fine-grained non-ferrous metal minerals, improve equipment installation flexibility and on-site adaptability, reduce on-site modification and debugging costs, and improve the utilization rate of mineral resources.

[0008] To achieve the above objectives, the present invention employs the following technical means: A novel shaking bed device includes a bed surface assembly, a bed frame support assembly, height-adjustable support legs, a base mounting base, a piston-type push drive mechanism, and a drive motor. The bed assembly is divided into a discharge side and a feed side, and the sorting slope of the bed assembly is adjustable from 1.0° to 4.5°; the bed frame support assembly is connected to the bottom of the bed assembly and is fixed to the top of the foundation mounting base by anchor bolts; The piston-type push drive mechanism is installed at the feed side end of the bed assembly, and the drive motor is installed on the piston-type push drive mechanism. The bottom of the bed frame support assembly is equipped with height-adaptive adjustable legs with a multi-position locking and positioning structure. The height of the support at both ends of the bed surface assembly can be adjusted by the height-adaptive adjustable legs to achieve precise matching between the bed surface sorting slope and the feeding and receiving heights. The piston-type push drive mechanism adopts a piston reciprocating push structure to drive the bed surface assembly to complete the reciprocating motion of mineral sorting.

[0009] Preferably, the matching parameters between the slope of the bed assembly and the feed and receiving heights are as follows: for a slope of 1.0°, the receiving height h = 530 mm and the feed height H = 960 mm; for a slope of 1.5°, the receiving height h = 525 mm and the feed height H = 975 mm; for a slope of 2.5°, the receiving height h = 520 mm and the feed height H = 1010 mm; for a slope of 3.5°, the receiving height h = 510 mm and the feed height H = 1030 mm; for a slope of 4.0°, the receiving height h = 505 mm and the feed height H = 1040 mm; and for a slope of 4.5°, the receiving height h = 500 mm and the feed height H = 1045 mm.

[0010] Preferably, the height-adaptive adjustable legs correspond to the feeding side and the discharging side of the supporting bed assembly, respectively, and can be independently raised, lowered, adjusted, and locked in position.

[0011] Preferably, the foundation mounting base is an integral concrete stepped base with pre-embedded grooves for anchor bolts, providing a rigid installation reference for the entire set of equipment.

[0012] Preferably, the piston-type push drive mechanism includes a reciprocating piston transmission assembly and a headstock housing. The reciprocating piston transmission assembly is rigidly connected to the bed surface assembly, which can convert the rotational power of the drive motor into a horizontal linear reciprocating push force, driving the bed surface assembly to perform stable asymmetrical reciprocating motion.

[0013] Preferably, the drive motor can be selectively installed at the front end or rear end of the headstock of the piston-type push drive mechanism to adapt to different factory space layouts and installation requirements.

[0014] The present invention has the following beneficial effects: 1. Significantly improved sorting and recovery efficiency. This invention adopts a piston-type linear push drive structure, replacing the traditional eccentric connecting rod intermittent impact drive. The reciprocating motion of the bed surface has uniform force and stable stroke, without severe impact vibration, effectively preventing the loss of fine non-ferrous metal particles with water flow. The interception and stratification of fine mineral particles are significantly improved, and the overall recovery rate of valuable metals is 10% higher than that of traditional 6S shaking tables and Yunnan tin shaking tables, greatly reducing the waste of mineral resources and improving resource utilization.

[0015] 2. Flexible equipment installation layout. The drive motor adopts a front-to-back switchable installation structure, which can be freely adjusted according to the space size of the ore dressing workshop and the layout of supporting equipment. This breaks the space limitations of the traditional fixed installation of shaking tables, adapts to the layout of new production lines and the renovation of old workshops, and makes the equipment more versatile.

[0016] 3. High adaptability to slope adjustment and low on-site modification cost. The bed surface can be adjusted in a wide range of slopes from 1.0° to 4.5°, and each slope level is precisely matched with a fixed feeding and receiving height. After the slope adjustment is completed, there is no need to modify the feeding chute, discharge pipeline and other supporting facilities. The slurry introduction and product discharge are smooth and stable, which greatly reduces the workload of on-site installation and commissioning and shortens the equipment commissioning cycle.

[0017] 4. High equipment stability and long service life. The integrated stepped concrete foundation provides a stable installation benchmark for the equipment, and the multi-position locking outriggers ensure strong support rigidity and no shaking after the bed surface is adjusted; the piston-type pushing structure has low impact during movement, significantly reducing equipment vibration and noise, effectively reducing wear on equipment components, extending the service life of the entire machine, and lowering equipment operation and maintenance costs.

[0018] 5. Wide range of applicable minerals. Specifically optimized for the separation of fine and micro-fine refractory non-ferrous metal ores, it can be adapted to gravity separation operations of various low-grade, fine-grained disseminated non-ferrous metal ores, solving the industry pain point of poor separation effect of traditional equipment for micro-fine minerals, and has a wide range of applicable scenarios. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 ; In the attached figures, the following labels are used: Bed surface assembly 1, discharge side 101, feed side 102, bed frame support assembly 2, height adaptive adjustable legs 3, foundation mounting base 4, piston-type push drive mechanism 5, drive motor 6. Detailed Implementation

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, this invention provides a novel shaking table device, comprising six core components: a bed surface assembly 1, a bed frame support assembly 2, height-adaptive adjustable support legs 3, a foundation mounting base 4, a piston-type pushing drive mechanism 5, and a drive motor 6. These components are precisely assembled and work in concert to achieve adaptive and efficient gravity separation of fine and micro-fine non-ferrous metal minerals. The bed surface assembly 1 is the core working surface for mineral separation, divided into a low-level discharge side 101 and a high-level feed side 102. The bed surface assembly 1 can achieve a continuously adjustable separation slope of 1.0° to 4.5°, allowing for flexible adjustment of the separation angle according to the particle size and mineral properties to adapt to different working conditions. The bed frame support assembly 2 is fixedly mounted at the bottom of the bed surface assembly 1, serving as the main load-bearing support for the bed surface. The bed frame support assembly 2 is detachably fixed to the top of the foundation mounting base 4 using anchor bolts, ensuring a stable assembly structure and convenient disassembly and assembly.

[0022] The bottom of the bed frame support assembly 2 is symmetrically equipped with height-adaptive adjustable legs 3 with multi-position locking and positioning structures. The height-adaptive adjustable legs 3 correspond one-to-one with the two ends of the feed side 102 and discharge side 101 of the bed surface assembly 1. The two legs can independently complete the lifting and lowering height adjustment, and after adjustment, they can be quickly locked and fixed by the locking structure to ensure the rigidity and stability of the support structure. This equipment has multiple pre-set sets of precisely matched slope-height parameter systems. Each bed surface sorting slope corresponds to a unique and fixed feed height H and discharge / receiving height h. The specific matching parameters are as follows: When the slope is 1.0°, the discharge / receiving height h = 530mm and the feed height H = 960mm; when the slope is 1.5°, the discharge / receiving height h = 525mm and the feed height H = 975mm; when the slope is 2.5°, the discharge / receiving height h = 520mm and the feed height H = 1010mm; when the slope is 3.5°, the discharge / receiving height h = 510mm and the feed height H = 1030mm; when the slope is 4.0°, the discharge / receiving height h = 505mm and the feed height H = 1040mm; when the slope is 4.5°, the discharge / receiving height h = 500mm and the feed height H = 1045mm. By precisely adjusting and locking the height-adaptive outriggers 3, the bed sorting slope and the feeding and receiving heights can be precisely matched one-to-one. After slope adjustment, there is no need to modify the external feeding chute or discharge pipeline, ensuring smooth slurry introduction and stable output of sorted products. The foundation installation base 4 is an integrated concrete stepped base with pre-embedded grooves for anchor bolts on the surface. The overall structure is rigid and has high load-bearing stability, providing a high-precision and high-stability installation benchmark for the entire set of equipment, effectively reducing equipment vibration and ensuring accuracy for long-term continuous operation.

[0023] The piston-type push drive mechanism 5 is fixedly installed at the feed side 102 end of the bed assembly 1, completely replacing the traditional eccentric connecting rod impact drive structure of the shaking table, and is the core power transmission component of the equipment. The piston-type push drive mechanism 5 has a built-in reciprocating piston transmission assembly and a sealed headstock housing. The reciprocating piston transmission assembly and the end of the bed assembly 1 are rigidly directly connected, ensuring zero backlash and zero offset in transmission. The matching drive motor 6 is the power input source, and the drive motor 6 has bidirectional installation adaptability. It can be selectively installed at the front end or rear end of the headstock housing according to the spatial layout of the ore dressing workshop and the arrangement requirements of surrounding equipment, greatly improving the flexibility of on-site installation of the equipment. When the drive motor 6 is running, it can efficiently convert the rotational power into a uniform and stable linear reciprocating push force in the horizontal direction, continuously driving the bed assembly 1 to perform a smooth asymmetrical reciprocating sorting motion, completely solving the problems of intermittent impact and severe vibration of the traditional eccentric connecting rod structure.

[0024] Working principle This novel shaking table device abandons the traditional eccentric linkage impact drive mechanism of the 6S shaking table and Yunnan Tin shaking table, and adopts a brand-new collaborative working mechanism of piston-type linear reciprocating push drive + slope-height adaptive matching. Relying on the core structure such as piston-type push drive mechanism 5, height adaptive adjustment support leg 3, and bed surface assembly 1 working together, it utilizes the multi-field coupling effect of mechanical power field, gravity field, and water flow shear field to achieve efficient stratification, zoning, and separation of fine particles, micro-fine particles, and difficult-to-select non-ferrous metal minerals and gangue. The overall working principle is divided into three parts: core overall principle, modular working principle, and whole machine collaborative operation process.

[0025] I. Core Principles of Overall Sorting This device uses a piston-type push-drive mechanism 5 as its power core, replacing the traditional intermittent impact drive structure with an eccentric connecting rod, providing the bed assembly 1 with a uniform and stable horizontal linear reciprocating thrust throughout its entire stroke. Simultaneously, the height-adaptive adjustable support legs 3 precisely control the sorting slope of the bed assembly 1 and match the corresponding standardized feeding and receiving heights, ensuring stable slurry feeding and smooth discharge of sorted products. Under the triple coupling effect of the reciprocating shear thrust of the bed assembly 1, the gravity of the mineral particles themselves, and the transverse flushing water flow, it achieves stratified separation of high-density non-ferrous metal fine mineral particles and low-density gangue particles, continuously completing the entire gravity separation process of feeding, stratification, separation, and discharge. This completely solves the problems of large impact vibration, easy loss of fine mineral particles, and poor sorting stability of traditional equipment, significantly improving the recovery rate of valuable metals from fine particles.

[0026] II. Detailed Working Principles of Each Module (I) Working principle of piston-type power drive module This module consists of a drive motor 6 and a piston-type push drive mechanism 5, providing a stable power source for the sorting motion of the equipment. The drive motor 6 can be selectively installed at the front or rear of the headstock of the piston-type push drive mechanism 5, depending on the factory space layout, offering excellent installation adaptability. After the drive motor 6 starts, it inputs rotational power into the reciprocating piston transmission assembly inside the headstock of the piston-type push drive mechanism 5. Through the rigid direct connection between the piston transmission structure and the bed assembly 1, the rotational power is precisely converted into a horizontal, linear reciprocating pushing force, continuously driving the bed assembly 1 to perform a smooth, asymmetrical reciprocating sorting motion.

[0027] Unlike the intermittent, impact-driven push of the eccentric linkage structure of traditional shaking tables, the piston-type push drive mechanism 5 of this device has a continuous and uniform pushing force throughout the entire process, a constant and unbiased motion stroke, and no instantaneous impact vibration. From the power source, it avoids the problem of fine non-ferrous metal mineral particles being washed away by violent vibration and instantaneous water turbulence, and provides the core power conditions for the stable stratification and precise interception of fine mineral particles on the bed surface component 1.

[0028] (II) Working principle of slope and height adaptive adjustment This module consists of a bed frame support assembly 2, height-adaptive adjustable support legs 3, and an integrated foundation mounting base 4, enabling adjustable slope of the bed surface assembly 1 and adaptive matching of installation height. The integrated concrete foundation mounting base 4 provides a high-strength, rigid installation reference for the entire machine, effectively suppressing equipment shaking and deformation during operation and ensuring the sorting accuracy of the bed surface assembly 1.

[0029] The bottom ends of the bed frame support assembly 2 are equipped with height-adaptive adjustable legs 3, each with a multi-position locking and positioning structure. These two legs are independently controllable and correspond to the feed side 102 and discharge side 101 of the bed surface assembly 1, respectively. On-site, the height of the two height-adaptive adjustable legs 3 can be independently adjusted according to the particle size and mineral characteristics of the ore to be separated, precisely controlling the sorting slope of the bed surface assembly 1. The adjustable range is 1.0° to 4.5°. The equipment has multiple preset sets of precise matching parameters. Each sorting slope uniquely corresponds to a set of standard feed height and receiving height. After the slope adjustment is completed, it is fixed by the locking structure of the height-adaptive adjustable legs 3, eliminating the need for manual fine-tuning of external equipment.

[0030] Slope-height precise matching logic: When the slope of the bed component 1 changes, the ground clearance height of the feed side 102 and the discharge side 101 is synchronously and adaptively adjusted to ensure stable slurry feed velocity and flow rate, and smooth discharge of sorted products. This eliminates the need to modify the feed chute, discharge pipeline, and other supporting facilities, completely solving the problems of difficult pipeline connection and large on-site modification workload after adjusting the slope of traditional shaking tables. Specific matching parameters are as follows: slope 1.0° (h=530mm, H=960mm), slope 1.5° (h=525mm, H=975mm), slope 2.5° (h=520mm, H=1010mm), slope 3.5° (h=510mm, H=1030mm), slope 4.0° (h=505mm, H=1040mm), slope 4.5° (h=500mm, H=1045mm).

[0031] (III) Working principle of mineral stratification, zoning and sorting The slurry is continuously and uniformly fed from the high-level feed side 102 of the bed assembly 1, while transverse separation and washing water is introduced. Mineral separation is completed by relying on multi-field coupling. The whole process is divided into three stages: stratification, zoning, and discharge. 1. Layering Stage: Under the stable reciprocating push of the piston-type push drive mechanism 5, the bed surface component 1 generates continuous and uniform shear force, forming a stable flow field inside the slurry. High-density fine non-ferrous metal ore particles sink rapidly under the action of gravity and adhere tightly to the bottom layer of the groove in the bed surface component 1; low-density gangue, sludge and other impurities are suspended in the upper layer of the slurry, realizing precise layering of light and heavy minerals and preventing the loss of fine metal particles.

[0032] 2. Zoning stage: The longitudinal reciprocating thrust of the bed surface component 1 continuously pushes the bottom heavy minerals to slowly move towards the discharge side 101, while the transverse flushing water flow uniformly pushes the upper light gangue to diffuse laterally, forming a clearly defined and stably distributed concentrate zone, middlings zone, and tailings zone on the surface of the bed surface component 1, realizing the orderly zoning of minerals of different grades.

[0033] 3. Discharge stage: After the stratification and separation are completed, the high-purity valuable metal concentrate moves smoothly along the longitudinal direction of the bed surface component 1 to the low discharge side 101 for collection; the middlings can be recycled and re-selected according to production needs; the light gangue and tailings automatically overflow from the bed surface component 1 with the transverse water flow, completing the continuous separation operation.

[0034] III. Complete Workflow of the Whole Machine 1. Equipment pre-installation and commissioning: Select the installation position of drive motor 6 according to the spatial layout of the ore dressing workshop, fix the bed frame support component 2 to the integrated foundation mounting base 4, and complete the rigid assembly of the whole machine; adjust the height adaptive adjustment leg 3 according to the particle size characteristics of the ore to be sorted, lock the target sorting slope and the corresponding standard feed and discharge height, and complete the precise connection of the pipeline.

[0035] 2. Equipment Start-up and Operation: Start the drive motor 6, which drives the internal transmission components of the piston-type push drive mechanism 5 to work continuously, driving the bed surface assembly 1 to perform stable linear reciprocating sorting motion.

[0036] 3. Continuous sorting operation: Slurry and flushing water are continuously fed into the bed assembly 1. Under the coupled action of shear force, mineral gravity and water flow impact force of the bed assembly 1, the fine-grained non-ferrous metal minerals and gangue are separated into layers and zones.

[0037] 4. Product classification and collection: Heavy valuable metal concentrate is stably recovered, and tailings are discharged with water overflow. The whole machine operates continuously and automatically, realizing efficient and stable fine mineral gravity separation production.

[0038] IV. Advantages of Core Working Mechanism Compared to the traditional eccentric linkage impact mechanism of shaking tables, the core mechanism of this device, namely the piston-type push drive mechanism 5 for smooth pushing and the height-adaptive adjustable support leg 3 for slope and height adaptive matching, completely eliminates the problems of equipment operation impact and slurry flow field disturbance, significantly improves the retention capacity of fine-grained minerals, effectively reduces the loss of valuable metals, and ultimately achieves a recovery rate of fine-grained non-ferrous metal minerals that is more than 10% higher than that of traditional equipment, while also taking into account the equipment's installation flexibility, working condition adaptability, and operational stability.

[0039] Example 1: Example of low-slope fine-grained non-ferrous metal ore beneficiation (slope 1.5°) This embodiment is applicable to the separation of ultrafine non-ferrous metal ores with a particle size of 0.01~0.03mm and low-concentration slurry. It adopts a small-slope stable flow field separation mode to avoid the overflow and loss of ultrafine mineral particles with water flow.

[0040] Equipment assembly method: Based on the long and narrow space layout of the ore dressing workshop, the drive motor 6 is installed at the rear end of the headstock of the piston-type push drive mechanism 5, saving front-end operating space; the bed frame support assembly 2 is fixed to the integrated concrete foundation mounting base 4 by anchor bolts to ensure the rigidity of the whole machine support; the bottom ends of the bed frame support assembly 2 are equipped with height-adjustable support legs 3, which support the feed side 102 and discharge side 101 of the bed surface assembly 1 respectively.

[0041] Slope and height adjustment parameters: The bed surface assembly 1 is precisely adjusted to 1.5° by independently raising and lowering and locking the height of the self-adaptive adjustable support leg 3. Matching standard working conditions parameters: ore receiving height h=525mm on the discharge side 101 and ore feeding height H=975mm on the feed side 102. No modification to the external feed chute and discharge pipeline is required, and the equipment can be directly connected and put into production.

[0042] Equipment operation process: The drive motor 6 is started, driving the reciprocating piston transmission component inside the piston-type push drive mechanism 5 to run at a uniform speed. This rigid direct connection drives the bed assembly 1 to perform continuous, uniform, and impact-free linear reciprocating motion, with stable stroke and uniform thrust. Low-concentration fine-particle slurry is smoothly fed in from the feed side 102, accompanied by a small flow of transverse flushing water. Under the coupled action of stable shear force, mineral gravity, and water flow traction force of the bed assembly 1, ultrafine valuable metal minerals quickly sink and adhere to the bottom of the grooves in the bed assembly 1, while low-density gangue is suspended in the upper flow field. Heavy minerals slowly move and accumulate towards the discharge side 101 with the stable longitudinal pushing force of the bed surface, while light gangue overflows smoothly with the transverse water flow. The entire flow field is turbulent and free from impact scouring.

[0043] Implementation results: For fine-grained non-ferrous metal ores of 0.01~0.03mm, the separation stability is extremely strong, with almost no loss of fine mineral particles. Compared with the traditional eccentric linkage shaking table, the recovery rate of valuable metals is increased by about 11%, which is perfectly adapted to the separation conditions of ultra-fine and difficult-to-separate minerals.

[0044] Example 2: Example of conventional fine-grained non-ferrous metal ore beneficiation on a medium slope (slope 3.5°) This embodiment is applicable to conventional production conditions of fine-grained non-ferrous metal ores with a particle size of 0.03~0.1mm and medium-concentration slurry. It represents the mainstream standardized sorting conditions in mines, balancing sorting efficiency and sorting accuracy.

[0045] Equipment assembly method: The ore dressing workshop has a spacious layout, so the drive motor 6 is installed at the front end of the headstock of the piston-type push drive mechanism 5, which facilitates daily inspection and maintenance of the equipment; the whole machine is assembled horizontally and precisely based on the foundation mounting base 4, the bed frame support component 2 bears stable load, and the height adaptive adjustable legs 3 on both sides are in an independent adjustable standby state.

[0046] Slope and height adjustment parameters: The height adaptive adjustment outrigger 3 is precisely adjusted and locked to adjust the sorting slope of the bed assembly 1 to 3.5°, matching the standard working condition parameters: the ore receiving height h of the discharge side 101 is 510mm, the ore feeding height H of the feed side 102 is 1030mm, and the overall total height of the feed side 102 is 1130mm. The equipment is fully compatible with the standard matching chute and pipeline on site, and can be connected with zero modification.

[0047] Equipment operation: The drive motor 6 operates under rated conditions, and the piston-type push drive mechanism 5 outputs a stable linear reciprocating thrust, driving the bed assembly 1 to continuously perform asymmetrical and stable reciprocating motion. The shearing force is moderate, and the sorting rhythm is stable. Medium-concentration slurry is continuously fed into the surface of the bed assembly 1 from the feed side 102. With the help of standard flow rate sorting and washing water, light and heavy mineral stratification is quickly achieved: high-density metal mineral particles adhere to the bottom and are enriched, while gangue particles float to the surface and are stratified. Under the synergistic effect of the longitudinal thrust of the bed and the transverse water flow, a clear concentrate zone, middlings zone, and tailings zone are quickly formed on the surface of the bed assembly 1. The concentrate is stably collected at a low position by the discharge side 101, the middlings can be recycled for further sorting, and the tailings overflow and are discharged, realizing continuous large-scale sorting production.

[0048] Implementation results: The conventional fine-grained mineral sorting has high precision, large processing capacity, and stable operation. Compared with the traditional 6S shaking table and Yunnan Tin shaking table, the comprehensive recovery rate of valuable metals is increased by 10%. The equipment operates continuously without vibration or deviation and without pipeline connection failures, making it suitable for normalized continuous production operations in mines.

[0049] Example 3: Example of separating coarse and fine-grained mixed ore on a steep slope (slope 4.5°) This embodiment is applicable to the separation of mixed coarse and fine non-ferrous metal ores with a particle size of 0.1~0.5mm and high-concentration slurry. It adopts a large slope and high thrust separation mode to improve the settling and discharge efficiency of coarse mineral particles.

[0050] Equipment assembly method: The workshop equipment is densely arranged. The drive motor 6 is switched and installed at the rear end of the headstock of the piston-type push drive mechanism 5 to avoid equipment interference. The foundation mounting base 4 provides a high-strength load-bearing benchmark for the whole machine. The bed frame support component 2, together with the height adaptive adjustable legs 3 on both sides, completes high-strength support to meet the requirements of heavy load sorting conditions.

[0051] Slope and height adjustment parameters: In view of the characteristics of fast settling speed and large sorting load of mixed coarse and fine ore, the slope of the bed assembly 1 is adjusted to the maximum adjustment value of 4.5° by adjusting the height adaptive support leg 3. After locking and fixing, the standard parameters are matched: ore receiving height h=500mm on the discharge side 101, ore feeding height H=1045mm on the feed side 102. The large slope is suitable for the rapid settling and separation of coarse ore.

[0052] Equipment operation: The drive motor 6 operates stably under full load, and the piston-type push drive mechanism 5 outputs a constant high thrust, driving the bed assembly 1 to reciprocate at high speed and provide sufficient shearing and stratification power for coarse-grained minerals. High-concentration mixed slurry is rapidly fed in from the feed side 102. The steep slope of the bed assembly 1 accelerates the flow and stratification of the slurry, causing coarse and fine high-density metallic minerals to quickly settle to the bottom and completely separate from the upper gangue slurry. The continuous reciprocating thrust of the bed assembly 1 rapidly pushes the bottom heavy minerals towards the discharge side 101, efficiently completing the discharge operation. The transverse water flow quickly carries away a large amount of light gangue and impurities, solving the problems of jamming and incomplete stratification in traditional shaking tables for large particle separation.

[0053] Implementation results: For difficult-to-sort minerals with mixed coarse and fine particles, the sorting efficiency is significantly improved, the processing capacity is higher than that of traditional equipment, the comprehensive recovery rate of valuable metals in coarse and fine particles is steadily increased by 9.5%~10.5%, and the equipment does not shake or loosen under high-load and steep-slope operation, and its operational stability is far superior to that of traditional equipment.

[0054] Summary of the generality of the three sets of implementation examples The three sets of embodiments respectively cover three mainstream sorting conditions: micro-fine particles, conventional fine particles, and mixed coarse and fine particles. Relying on the core structure of the piston-type push drive mechanism 5 for smooth drive and height adaptive adjustment support leg 3 for slope height adaptive matching, all of them can achieve zero on-site modification, flexible layout, and efficient sorting operation. Compared with traditional shaking table equipment, it has wider adaptability, higher recovery rate, and more stable operation, fully demonstrating the innovation and engineering practical value of the present invention.

Those skilled in the art will recognize that various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations, and any obvious variations or modifications derived therefrom are still within the scope of this invention.
