Abstract
Description
Technical Field
[0001] This invention relates to the field of mining development technology, specifically to a particle size control system and method for a two-stage semi-crushing process. Background Technology
[0002] In the processing of hard rock materials such as ores and building materials, the two-stage closed-circuit or two-stage semi-crushing process is one of the most widely used crushing processes. Its typical process usually includes a closed-circuit cycle consisting of coarse crushing (jaw crusher, etc.), medium crushing (cone crusher or impact crusher, etc.) and screening equipment. In this process, the screening equipment (usually a vibrating screen) undertakes the crucial task of particle size control and classification. Its screen specifications directly determine the particle size composition of the final product and the system circulation load.
[0003] Once a fixed-mesh screen is installed, its screening size cannot be changed. When the downstream market of the mined ore raises new requirements for product particle size specifications, the machine must be stopped and the screen manually replaced. This process is not only time-consuming and labor-intensive, reducing effective production time, but also makes the entire production line unable to respond quickly to changes, resulting in extremely poor flexibility. The particle size control of the existing process is essentially a "post-inspection" mode. After the material is crushed, it is separated in the screening stage. Qualified material passes through the screen, while unqualified material (oversize material) is returned to the crusher for further crushing. This control method has significant lag. The system cannot predict and intervene in the particle size of the material during the crushing process, resulting in large fluctuations in the product particle size distribution. In particular, when the fragility of the raw material changes, it is very easy to produce "over-crushing" (producing too much fine powder), which not only wastes energy and increases equipment wear, but also reduces the yield of finished products that meet the target particle size. Summary of the Invention

[0010] Preferably, a fixed eccentric toothed ring is connected to one end of the synchronous shaft, and a movable eccentric toothed ring is connected to the bottom end of the screening component, with the top surface of the fixed eccentric toothed ring fitting against the movable eccentric toothed ring.

The extrusion concave wheel and the forming concave wheel are located inside the forming sheet.
[0014] Preferably, a method for a particle size control system in a two-stage semi-crushing process includes the following steps: S1. First, start the drive motor, which drives the movable frame to move through the eccentric shaft. Larger ore is fed between the extrusion plate and the jaw crusher to coarsely crush the larger ore. The coarsely crushed ore will enter the outer shell through the interface. The conical head at the top of the guide frame will disperse the ore, allowing it to fall directly between the intermediate crushing component and the inner tooth assembly for secondary crushing. S2. The explosion-proof motor drives the active tower wheel, which in turn drives the driven tower wheel to rotate via a belt. This, in turn, drives the auxiliary crushing component and the intermediate crushing component to rotate synchronously, thus performing secondary crushing of the crushed stone. The rotating intermediate crushing component has multiple sets of crushing components, which are independently controlled. The built-in motor can be started to drive the rotating frame to rotate via the drive frame. The rotating frame can push the movable crushing teeth out of the rotating housing via a connecting rod, thereby reducing the distance between the movable crushing teeth and the inner tooth components and increasing the crushing effect on the crushed stone. The intermediate crushing component consists of three sets of crushing components, which can gradually adjust the crushing degree to ensure the crushing effect. S3. The crushed stone after being crushed by the medium crushing component will fall onto the surface of the screening component. While the auxiliary crushing component drives the medium crushing component to rotate through the synchronous shaft, it will also drive the fixed eccentric toothed ring to rotate. Since the fixed eccentric toothed ring and the movable eccentric toothed ring are set with oblique teeth, when the fixed eccentric toothed ring rotates, it will cooperate with the movable eccentric toothed ring to lift the screening component upward. After rotating to a certain angle, the vibrating screen spring will pull the screening component to return to its original position downward, thereby achieving the vibration effect. The screening mesh of the screening component can be adjusted by adjusting the component. When the crushed stone falls onto the screening component, multiple high-speed cameras can take pictures of the crushed stone to determine the crushed particle size. S4. When some crushed stone remains on the screening component, increase the screening mesh size to discharge the remaining crushed stone, and then perform final crushing through the auxiliary crushing component to ensure the crushing effect.
[0015] In summary, the beneficial effects of this invention are: The automatically adjustable screening component allows for rapid adjustment of the screening mesh size without manual intervention or machine downtime, increasing processing flexibility, saving time and effort, and reducing labor costs. Built-in monitoring of particle size during secondary crushing allows for control of the distance between the crushing components and the internal tooth assembly, further ensuring the crushed particle size. Direct adjustment of the crushed particle size can further enhance crushing capabilities, broaden the applicability range, and guarantee production efficiency and quality, preventing over-crushing or under-crushing. Furthermore, the internal tooth assembly converts some of the mechanical energy generated during crushing into electrical energy for collection, effectively achieving energy conservation and environmental protection.

A connecting sleeve 11 is connected to the surface of the outer shell 1. A reinforcing frame 12 is connected to one side of the connecting sleeve 11. A connecting plate 13 is connected to the top of the reinforcing frame 12 and the outer shell 1. A coarse crushing frame 141 is connected to the top of the connecting plate 13. An extrusion plate 14 is connected to one side of the inner wall of the coarse crushing frame 141. A drive motor 17 is connected to one side of the coarse crushing frame 141. An eccentric shaft 18 is connected to the output end of the drive motor 17. A movable frame 15 is connected to the middle of the eccentric shaft 18. A jaw crushing plate 16 is connected to one side of the movable frame 15. A spring rod 20 is connected to the other side of the movable frame 15. A driven tower wheel 22 is connected to the bottom of the auxiliary crushing component 7. An explosion-proof motor 23 is connected to one side of the outer shell 1. An active tower wheel 24 is connected to the output end of the explosion-proof motor 23. A belt 25 is sleeved between the active tower wheel 24 and the driven tower wheel 22. Reference Figure 1 and Figure 2 As shown, the top of the outer shell 1 is connected to an interface 131 for connecting with the coarse crushing component above. A guide frame 9 is connected to the inner wall surface of the outer shell 1 at the position corresponding to the interface 131. The guide frame 9 includes a fixing ring 91 fixedly installed on the inner wall surface of the outer shell 1. Multiple sets of connecting grooves 92 are connected to the inner side of the fixing ring 91. Conical heads 93 are connected between the connecting grooves 92. When the coarse crushing component above crushes the ore, it will fall onto the conical head 93. The conical head 93 can evenly disperse the crushed stone, which will fall between the intermediate crushing component 6 and the inner tooth assembly 5.
[0020] Reference Figure 4As shown, the internal gear assembly 5 includes a fixed cone sleeve 51 fixedly mounted on the inner wall surface of the inner liner kit 4. A crushing cone block 52 is connected inside the fixed cone sleeve 51. A piezoelectric ceramic 53 is connected to the back of the crushing cone block 52. A support plate 54 is connected to the back of the piezoelectric ceramic 53. A damping rubber column 55 is connected to the back of the support plate 54. The damping rubber column 55 is fitted and installed on one side of the inner liner kit 4. The piezoelectric ceramics 53 in the multiple sets of internal gear assemblies 5 are electrically connected in parallel. A control cabinet is connected to one side of the outer casing 1, and the piezoelectric ceramics 53... It is electrically connected to the control cabinet, which contains electrical components such as a rectifier bridge, voltage regulator / smoothing circuit, and energy storage element. It can collect the voltage generated by the piezoelectric ceramic 53 when it is subjected to impact and extrusion. When the crushing component 6 or the auxiliary crushing component 7 rotates, it will cooperate with the crushing cone 52 to crush the gravel. After the crushing cone 52 is squeezed, it will squeeze the piezoelectric ceramic 53, thereby causing the piezoelectric ceramic 53 to generate voltage (i.e., piezoelectric effect). The damping rubber column 55 located at the rear provides a protective effect.
[0021] Reference Figure 5 and Figure 3 As shown, both the auxiliary crushing component 7 and the intermediate crushing component 6 are composed of multiple crushing assemblies. Each crushing assembly includes a rotating housing 26. Two sets of movable crushing teeth 27 are slidably arranged inside the rotating housing 26. A connecting bolt 28 is connected to one end of each movable crushing tooth 27. A connecting rod 29 is rotatably arranged on one side of each connecting bolt 28. The connecting rod 29 inside each set of movable crushing teeth 27 is connected to the same rotating frame 30. A drive frame 31 is connected to the inside of the rotating frame 30. The two rotating frames 30 are fixedly connected. An internal motor 32 is connected to the bottom of the inner wall of the body 26. The output end of the internal motor 32 is connected to the drive frame 31. Multiple sets of guide strips 33 are connected to each movable crushing tooth 27 on the inner wall of the rotating housing 26. The internal motor 32 drives the rotating frame 30 to rotate through the drive frame 31. The two sets of rotating frames 30 will push the movable crushing teeth 27 out of the rotating housing 26 through the connecting rod 29, and pull them in in the opposite direction, thereby controlling the gap between the movable crushing teeth 27 and the inner tooth assembly 5, and thus controlling the particle size of the crushing.
[0022] Reference Figure 7 As shown, a fixed eccentric toothed ring 222 is connected to one end of the synchronous shaft 61, and a movable eccentric toothed ring 111 is connected to the bottom end of the screening component 8. The top surface of the fixed eccentric toothed ring 222 is in contact with the movable eccentric toothed ring 111. While the intermediate crushing component 6 and the auxiliary crushing component 7 are rotating, the synchronous shaft 61 will drive the fixed eccentric toothed ring 222 to rotate. Through the shape matching between the fixed eccentric toothed ring 222 and the movable eccentric toothed ring 111, the screening component 8 will be lifted up. With continuous rotation, it will reset again. The screening component 8 will vibrate through the setting of the vibrating screen spring 802.
[0023] Reference Figure 9As shown, the screening component 8 includes a rigid plate 81, a rubber base 82 connected to the bottom of the rigid plate 81, and multiple adjustable flares 83 connected to the top of the rigid plate 81. The adjustable flares 83 are fixedly connected to the rubber base 82. A fixing frame 84 is connected to the inner side of the rigid plate 81, and a support plate 85 is connected to the bottom of the fixing frame 84. The bottom of the support plate 85 abuts against the rubber base 82. Adjustment components 86 are connected to the four corners of the fixing frame 84. An external negative pressure air source is connected to one side of the 81 through an air pipe. The adjustable flares 83 and the rubber base 82 are integrated. When the external negative pressure air source draws air from the rigid plate 81 and the rubber base 82, the adjustable flares 83 will tightly fit against one side of each adjustment component 86. By adjusting the adjustment components 86, the size of the holes on the bottom of the rubber base 82 can be controlled, thereby adjusting the screening mesh.
[0024] Reference Figure 10 As shown, the adjusting assembly 86 includes a connecting frame 861 fixedly mounted on the top of the rubber base 82 and a traction head 862 connected to one side of the fixed frame 84. A bird's head frame 863 is rotatably mounted at the middle of the connecting frame 861. A molding piece 865 is connected to one side of the traction head 862, and a limit frame 864 is connected to the other end of the molding piece 865. The limit frame 864 is fixedly mounted on the top of the rubber base 82. An extrusion concave wheel 866 is connected to one side of the bird's head frame 863, and the other side of the bird's head frame 863 is rotatable. A miniature electric actuator 867 is provided, with its top end rotatably connected to a rigid plate 81. A movable extrusion component is connected to one end of a bird head frame 863. When the miniature electric actuator 867 retracts, it drives the bird head frame 863 to rotate. When the bird head frame 863 rotates, it extrudes the concave roller 866 to form a sheet 865. At the same time, the movable extrusion component in the multiple sets of adjustment components 86 will relatively disperse, thereby making the hole formed between the adjustable flare 83 and the rubber base 82 larger, which facilitates the adjustment of the screen hole.
[0025] Reference Figure 11 As shown, the movable extrusion assembly includes a fixed tube 34 fixedly mounted at one end of the bird head frame 863. A piston 35 is slidably mounted inside the fixed tube 34. An extrusion spring 36 is connected between the piston 35 and the inner wall of the fixed tube 34. A piston rod 37 is connected to one side of the piston 35, and a C-frame 38 is connected to the other end of the piston rod 37. A ring 39 is connected to one side of the C-frame 38. A forming concave wheel 40 is rotatably mounted between the rings 39. The extrusion concave wheel 866 and the forming concave wheel 40 are located inside the formed sheet 865. When 863 rotates, it will drive the movable extrusion assembly to rotate. When rotating, the fixed tube 34 will rotate with it, thereby driving the piston rod 37 and the forming concave wheel 40 to rotate together. At this time, the piston 35 will slide into the fixed tube 34 to satisfy the change of rotation radius, while ensuring the support of the forming concave wheel 40 for the formed sheet 865, ensuring the tension of the formed sheet 865, and thus providing the plastic effect of the adjustable flare 83 under negative pressure.
[0026] A method for a particle size control system in a two-stage semi-crushing process includes the following steps: S1. First, start the drive motor 17, which drives the movable frame 15 to move through the eccentric shaft 18, and feed the larger ore between the extrusion plate 14 and the jaw crusher 16 to coarsely crush the larger ore. The coarsely crushed ore will enter the outer shell 1 through the interface 131. The conical head 93 at the top of the guide frame 9 will disperse the ore, so that the ore will fall directly between the intermediate crushing component 6 and the inner tooth assembly 5 for secondary crushing. S2. The explosion-proof motor 23 drives the active tower wheel 24, which in turn drives the driven tower wheel 22 to rotate via the belt 25. This, in turn, drives the auxiliary crushing component 7 and the intermediate crushing component 6 to rotate synchronously, thus performing secondary crushing of the crushed stone. The rotating intermediate crushing component 6 has multiple crushing components, which are independently controlled. The built-in motor 32 can be started, which drives the rotating frame 30 to rotate via the drive frame 31. The rotating frame 30 can push the movable crushing tooth 27 out of the rotating housing 26 via the connecting rod 29, thereby reducing the distance between the movable crushing tooth 27 and the inner tooth component 5 and increasing the crushing effect on the crushed stone. The intermediate crushing component 6 has three crushing components, which can gradually adjust the crushing degree to ensure the crushing effect. S3. The crushed stone after being crushed by the intermediate crushing component 6 will fall onto the surface of the screening component 8. While the auxiliary crushing component 7 drives the intermediate crushing component 6 to rotate through the synchronous shaft 61, it will also drive the fixed eccentric toothed ring 222 to rotate. Since the fixed eccentric toothed ring 222 and the movable eccentric toothed ring 111 are set with oblique teeth, when the fixed eccentric toothed ring 222 rotates, it will cooperate with the movable eccentric toothed ring 111 to lift the screening component 8 upward. After rotating to a certain angle, the vibrating screen spring 802 will pull the screening component 8 downward to reset, thereby achieving the vibration effect. The screening mesh of the screening component 8 can be adjusted by adjusting the component 86. When the crushed stone falls onto the screening component 8, multiple high-speed cameras 10 can take pictures of the crushed stone to determine the crushed particle size. S4. When some crushed stone remains on the screening component 8, the screening mesh size is increased to discharge the remaining crushed stone, and the auxiliary crushing component 7 is used for final crushing to ensure the crushing effect.

10. A method for particle size control system in a two-stage semi-crushing process according to claim 9, characterized in that, Includes the following steps: S1. First, start the drive motor (17), and drive the movable frame (15) to move through the eccentric shaft (18). The larger ore is fed between the extrusion plate (14) and the jaw crusher (16) to coarsely crush the larger ore. The crushed ore will enter the outer shell (1) through the interface (131). The conical head (93) at the top of the guide frame (9) will disperse the crushed ore, so that the crushed ore falls directly between the intermediate crushing component (6) and the inner tooth component (5) for secondary crushing. S2. The explosion-proof motor (23) drives the active tower wheel (24), which drives the driven tower wheel (22) to rotate via the belt (25), thereby driving the auxiliary crushing component (7) and the intermediate crushing component (6) to rotate synchronously for secondary crushing of the crushed stone. The rotating intermediate crushing component (6) has multiple crushing components, which are independently controlled. The built-in motor (32) can be started, and the rotating frame (30) can be driven to rotate via the drive frame (31). The rotating frame (30) can push the active crushing tooth (27) to the outside of the rotating housing (26) via the connecting rod (29), thereby reducing the distance between the active crushing tooth (27) and the inner tooth component (5) and increasing the crushing effect on the crushed stone. The intermediate crushing component (6) consists of three crushing components, which can gradually adjust the crushing degree to ensure the crushing effect. S3. After being crushed by the medium crushing component (6), the crushed stone will fall onto the surface of the screening component (8). When the auxiliary crushing component (7) drives the medium crushing component (6) to rotate through the synchronous shaft (61), it will also drive the fixed eccentric toothed ring (222) to rotate. Since the fixed eccentric toothed ring (222) and the movable eccentric toothed ring (111) are set with oblique teeth, when the fixed eccentric toothed ring (222) rotates, it will cooperate with the movable eccentric toothed ring (111) to lift the screening component (8) upward. After rotating to a certain angle, the vibrating screen spring (802) will pull the screening component (8) to return to its original position downward, thereby achieving the vibration effect. The screening mesh of the screening component (8) can be adjusted by adjusting the component (86). When the crushed stone falls onto the screening component (8), multiple high-speed cameras (10) can take pictures of the crushed stone to determine the crushed particle size. S4. When some crushed stone remains on the screening component (8), the screening mesh size is increased to discharge the remaining crushed stone, and the auxiliary crushing component (7) is used for final crushing to ensure the crushing effect.
