[0002] In the lithium-ion battery products commonly found in the current market, graphite materials are often used as negative electrode materials, and graphite processed products with specific particle size, higher tap compaction and lower specific surface area are particularly preferred. In the previous graphite product processing technology, graphite materials were often processed at a lower operating frequency and a lighter collision force, in order to shape the material particles without damaging the surface morphology of the material as much as possible, so as to achieve the purpose of improving tap compaction. However, the existing process often requires multiple shaping equipment to be connected in series. If a single pass is over-shaped, the material specific surface area will increase rapidly.

[0003] Therefore, there is an urgent need to provide a technical solution that can improve the compaction of graphitized materials with a single processing equipment. Utility Model Content

[0035] The specific implementation manners of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 , Figure 1Shows an exemplary front view of a shaping device according to some embodiments of the present disclosure. In some embodiments, the shaping device includes a main housing 101. The main housing 101 may include, for example, a housing having a receiving cavity 110, as well as a feed inlet 120 and a discharge outlet 121 communicating with the receiving cavity 110. The feed inlet 120 and the discharge outlet 121 may be located on the lateral sides of the main housing 101 respectively, for feeding materials into the receiving cavity 110 and discharging the processed materials in the receiving cavity 110. At least one hammer disk 131 rotatable relative to the receiving cavity 110 may be provided in the receiving cavity 110. The hammer disk 131 may include a disk body generally in a disk shape, and a plurality of hammers 130 spaced along the circumferential direction of the disk body on the surface of the disk body. The plurality of hammers 130 may protrude outward from the outer peripheral edge of the disk body 131 for touching and shaping the materials to be processed in the receiving cavity 110.

[0037] In addition, one side of the housing of the main housing 101 facing the receiving cavity 110, i.e., the inner wall 113 of the housing, is provided as an arc concentric with the hammer disk 131. A spheroidization cavity 150 for spheroidizing the materials is defined between the inner wall 113 of the housing and the outer peripheral wall edge of the hammer disk 131. The spheroidization cavity 150 is used to accommodate the materials to be processed, and through the mutual movement between the plurality of hammers 130 and the inner wall 113 of the housing when the hammer disk 131 rotates, collisions occur between the hammers 130 and the materials, between the materials and the materials, and between the materials and the inner wall 113 of the housing, so as to shape the materials. Using the rotating hammers 130 to strike and collide with the materials can generate a higher shaping intensity compared with other methods, enabling the flaky materials to form balls in a shorter time, thus greatly shortening the entire process, obtaining higher production capacity, yield, and higher tapped density.

[0038] In addition, referring to Figure 2 , Figure 2An exemplary cross-sectional view of a hammer disk and a portion of the inner wall 113 of the shell of a shaping device according to some embodiments of the present disclosure is shown. A plurality of auxiliary shaping members protruding along the inner wall 113 of the shell toward the spheroidizing cavity 150 may also be provided on the inner wall 113 of the shell. When the hammer disk 131 rotates, the protruding auxiliary shaping members can increase the degree of volume change of a local portion in the spheroidizing cavity 150, thereby further strengthening the collision and pushing of the material. In some embodiments, the auxiliary shaping member may include a vertical grinding column 140 protruding along the inner wall 113 of the shell toward the spheroidizing cavity 150. The vertical grinding column 140 may be a long cylindrical body made of a material such as carbon steel, one end of which along the length direction is fixedly connected to the inner wall 113 of the shell by welding or the like, and the other end may extend toward the spheroidizing cavity 150. When the hammer disk 131 rotates, the vertical grinding column 140 can not only work together with the hammer heads 130 protruding from the hammer disk 131 to shear and squeeze the material in the spheroidizing chamber 150, but can also use its long strip shape to move the material, so that the flow direction of the material particles will change more, thereby further increasing the number and intensity of material collisions and improving the spheroidizing efficiency.

[0039] The auxiliary shaping member may also include a transverse grinding column 141 fixedly arranged along the inner wall 113 of the shell. The transverse grinding column 141 may be a long strip-shaped column extending in a direction parallel to the rotation axis of the hammer disk 131, and may be arranged along the inner wall 113 of the shell, for example. The transverse grinding column 141 can further improve the volume change degree of the local part in the spheroidization cavity 150, and can provide a storage position for the material in the spheroidization cavity 150 by means of the side of the protruding part of the inner wall 113 of the shell. Thus, when the hammer disk 131 rotates, the hammer 130 moves the material to collide and squeeze the material accumulated on the transverse grinding column 141, and the side wall of the transverse grinding column 141 will also provide support for the colliding material, thereby increasing the probability and intensity of the material collision. In some embodiments, a plurality of transverse grinding columns 141 may be closely arranged on the inner wall 113 of the shell adjacent to each other, and form a lining plate covering the inner wall 113 of the shell. The lining plate can enhance the structural strength of the inner wall 113 of the shell, and also reduce the wear caused by the frequent impact of materials on the inner wall 113 of the shell.

[0040] In some embodiments, the housing further has a housing outer wall 115, which can be formed substantially outside the housing inner wall 113, or the housing inner wall 113 and the housing outer wall 115 can be arranged in a concentric manner, so that the portion of the host chamber 101 corresponding to the housing outer wall 115 has a uniform wall thickness. A plurality of mounting holes penetrating into the spheroidizing cavity 150 can be arranged on the housing, and the vertical grinding column 140 can extend into the spheroidizing cavity 150 through the mounting holes and be fixed to the housing.

[0041] For example, in some embodiments, threads may be provided inside the mounting holes, and the vertical grinding column 140 may be the stud portion of a bolt. The bolt first passes through a fastening block and is then screwed into the inside of the mounting hole and fixed. The fastening block may be made of a flexible material such as rubber, for example, to buffer the vibrations generated during the operation of the device and reduce the occurrence of bolt loosening. In some embodiments, the fastening block may also adopt a structure such as a combination of a spring washer and a hard material spacer such as metal. By providing the detachable vertical grinding column 140 mounted through the mounting holes in the outer wall 115 of the housing, the worn vertical grinding column 140 can be quickly replaced from the outside of the device without opening the equipment for repair from the receiving cavity 110, significantly improving the convenience of equipment maintenance.

[0042] In some embodiments, the shaping device may include at least two hammer discs 131, and the spheroidizing cavities 150 corresponding to at least two hammer discs 131 are in communication with each other, so that the material can move from the vicinity of one hammer disc 131 to the vicinity of another hammer disc 131 therein. Referring again to Figure 1 , Figure 1 the shaping device shown in includes three hammer discs 131, two of which are located on the lower vertical side and one hammer disc 131 is located in a position slightly above the middle of the other two, such that the three hammer discs 131 are arranged in a roughly "pin" shape. At the same time, there is a spaced space between the outer edges of the three hammer discs 131 and the corresponding inner wall 113 of the housing. Thus, three spheroidizing cavities 150 are defined between the inner wall 113 of the housing and the outer peripheral edges of the three hammer discs 131. Since the three hammer discs 131 are arranged in a "pin" shape, the spaced spaces corresponding to two adjacent hammer discs 131 can communicate along the tangential direction of the edge of the hammer disc 131, thereby forming a continuous material passage in the receiving cavity 110, which ensures that while the internal structure of the equipment is compact, the flow of the material in the equipment can be made as smooth as possible.

[0043] At the same time, the three hammer discs 131 arranged in a "pin" shape also provide a moving path with a height difference for the material. When the material moves along the moving path driven by the rotation of the hammer disc 131 or the air flow, additional movement and collision are generated due to the height difference, further enhancing the spheroidizing efficiency.

[0044] Also referring to Figure 3a - Figure 3c , Figure 3a shows an exemplary front view of the hammer head of the shaping device according to some embodiments of the present disclosure; Figure 3b shows an exemplary side view of the hammer head of the shaping device according to some embodiments of the present disclosure; Figure 3c shows an exemplary top view of the hammer head of the shaping device according to some embodiments of the present disclosure.

[0045] In some embodiments, the hammer head 130 includes a hammer head body 135 and a hammer head reinforcement plate 137. The hammer head body 135 includes a substantially cuboid-shaped main body, one end of which protrudes along the length direction to form a semi-circular end face. It also includes a hammer head reinforcement plate 137 in the shape of a substantially rectangular sheet. The hammer head reinforcement plate 137 is fixedly arranged on one side surface of the hammer head body 135, and its plate surface is parallel to the axis of the semi-circular end face. The hammer head reinforcement plate 137 can be made of an alloy material, and it is welded together with the hammer head body 135 to an axial end face of the hammer head disk 131. Since the hammer head reinforcement plate 137 is arranged on the side surface where the hammer head 130 frequently contacts and rubs against the material, it can reduce the deformation and even damage of the hammer head body 135 due to frequent friction. Also refer to Figure 2 , a plurality of hammer heads 130 are arranged at certain angular intervals along the circumferential direction of the disk body. The semi-circular end face of the hammer head body 135 can protrude beyond the outer edge of the disk body of the hammer head disk 131 to be close to the inner wall 113 of the housing, so as to increase the influence range on the material. By using the hammer head 130 with a semi-circular end, when the hammer head disk 131 rotates, it will contact the material with an arc-shaped side surface and perform shaping, so as to have a better touching and squeezing effect, and reduce the occurrence of material crushing and surface topography change caused by the direct contact of the sharp edges of the hammer head 130 with the material.

[0046] In addition, the technical solution of this disclosure further includes a shaping machine, and the shaping machine includes the above-mentioned shaping device.

[0047] Refer to Figure 4 and Figure 5 , Figure 4 shows an exemplary front view of the shaping machine according to some embodiments of this disclosure; Figure 5 shows an exemplary front view of the shaping device, the feeding and grading assembly, and the feeding bin part of the shaping machine according to some embodiments of this disclosure. In some embodiments, the shaping machine 200 can include the above-mentioned shaping device 1 and a feeding and grading assembly communicated with the shaping device 1. The feeding and grading assembly can include a grading bin body 6 and an air flow driving assembly. The grading bin body 6 can be communicated with the feeding port 120 of the above-mentioned shaping device through an air flow channel such as a pipeline. The air flow driving assembly is communicated with the air flow channel and forms a conveying air flow by directionally conveying air into the air flow channel, so that the conveying air flow can circulate and convey the material between the grading bin body 6 and the shaping device 1.

[0048] Specifically, in some embodiments, the grading bin 6 may, for example, have a material inlet 63 and a discharge port 65 provided on its side wall. The material inlet 63 may be communicated with the discharge port 121 of the shaping device 1 through a pipeline, and the discharge port 65 may be communicated with the feed inlet 120 of the shaping device 1 through a pipeline. Further, an air flow driving component may be provided on the pipeline. The air flow driving component may be, for example, a valve or a component such as an air pump. By adjusting the outlet direction and size of the air flow driving component, a directional conveying air flow can be formed in the pipeline, so that it reaches the feed inlet 120 of the shaping device 1 from the discharge port 65 of the grading bin 6, then passes through the spheroidizing cavity 150 from the feed inlet 120 to the discharge port 121, and finally reaches the material inlet 63 of the grading bin 6. Thus, the material spheroidized in the shaping device 1 can form an automatic cycle between the grading bin 6 and the shaping device 1 by means of the conveying air flow. The cycle structure is simple, the conveying speed is fast, the time required for the material during the conveying process is less, and it is very suitable for the process of processing materials through cyclic processing. In addition, with the conveying of the air flow, the material particles will be more loose, and it will be easier for them to be screened and separated in the grading bin 6, thereby further improving the processing efficiency.

[0049] A filter element 67 for screening materials may also be provided in the grading bin 6. For example, the inner cavity of the grading bin 6 may be divided into two sides by a filter element 67 such as a filter screen or grading blades. The grading blades may rotate in the grading bin 6 to filter and screen the materials. An air flow outlet 61 is provided on the first side of the filter element 67. The air flow outlet 61 may be connected to a negative pressure device or other devices capable of receiving air flow and powdery residual materials. The second side may be provided with the above-mentioned material inlet 63 and discharge port 65. The filter element 67 can separate materials with large particle sizes and small particle sizes. For example, by setting the filtering parameters of the filter element 67, materials with a particle size less than n microns can pass through, while materials with a particle size greater than n microns are blocked. Thus, after the material enters the second side of the inner cavity of the grading bin 6 from the material inlet 63, the air flow outlet 61 can suck the inner cavity of the grading bin 6, so that the material on the second side moves towards the filter element 67. The small particle powdery residual materials with a particle size less than n microns pass through the filter element 67 and enter the first side, and are discharged from the air flow outlet 61, while the large particle materials with a particle size greater than n microns are blocked on the second side and are finally discharged from the discharge port 65 or continue to be sent to the shaping device 1 for further shaping processing.

[0050] In some embodiments, the grading bin 6 may include a generally cylindrical main body, and the axis of the cylindrical main body is arranged in the vertical direction. At this time, its upper vertical side is the above-mentioned first side, and its lower vertical side is the above-mentioned second side, and the filter element 67 is arranged at the middle position to separate the upper vertical side and the lower vertical side. The lower vertical side of the grading bin 6 may include a generally conical discharge hopper 62. The material inlet 63 is arranged on the side wall of the discharge hopper 62, and the above-mentioned discharge port 65 is arranged at the tip of the conical structure on its lower vertical side. A discharge gate 8 for controlling the opening and closing of the discharge port 65 may also be arranged at the discharge port 65. At the same time, the top of the upper vertical side of the cylindrical main body may be provided with the above-mentioned air outlet 61. The air outlet 61 may be communicated with an external air flow generating device, for example, to provide a suction air flow inside the grading bin 6. Thus, after the material is conveyed by the conveying air flow in the air flow channel to the lower vertical side of the grading bin 6, the negative pressure at the air outlet 61 can attract the material particles, so that the remaining material with small particle size in the material passes through the filter element 67 and enters the upper vertical side, and then is discharged through the air outlet 61. The large particle material that cannot pass through the filter element 67 will fall to the bottom of the discharge bin due to its own weight and reach and stay at the discharge port 65.

[0051] In addition, a secondary blowing assembly 7 may be arranged on the lower vertical side of the grading bin. The secondary blowing assembly 7 may include components such as a pneumatic valve or a pneumatic pump for providing a dispersing air flow to the lower vertical side of the grading bin 6. The secondary blowing assembly 7 may be arranged to provide a dispersing air flow towards the side wall of the discharge bin or near the material inlet 63. The dispersing air flow is used to fully disperse and wash the particulate material entering from the material inlet 63, so as to separate the materials with different particle sizes, which is convenient for the filter element 67 to perform screening and grading. At the same time, in some embodiments, the discharge port 65 may be arranged directly above the feed port 120 of the shaping device 1. The discharge port 65 and the feed port 120 may be connected to each other by a pipe arranged in the vertical direction, so that the material reaching the discharge port 65 can fall into the feed port 120 of the shaping device 1 due to its own weight.

[0052] In addition, a main discharge gate 16 may be arranged between the discharge port 65 and the shaping device 1. The main discharge gate 16 is connected to a main discharge port. When the main discharge gate 16 is opened, the finished product material inside the shaping machine can be discharged through the main discharge port.

[0053] In some embodiments, the air flow outlet 61 may further be connected to the dust collection assembly 10. The dust collection assembly 10 may include, for example, a dust collection bin 102. At the top of the dust collection bin 102, there is a main suction port 103. On the side of the dust collection bin 102, there is a dust collection inlet 105. And at the bottom of the dust collection bin 102, there is a dust collection hopper 107 that is generally pyramidal or conical. The tip of the dust collection hopper 107 extends vertically downward and is provided with a dust outlet gate 11. Among them, the main suction port 103 may be connected to the fan assembly 12. The fan assembly 12 may include, for example, a vacuum pump, so as to provide negative pressure towards the overall internal space of the shaping machine through the main suction port 103. The dust collection inlet 105 is in communication with the air flow outlet 61 of the classification bin body 6, so as to receive the small particle materials filtered out by the classification bin body 6. The filtered small particle materials may stay in the dust collection bin 102 and be discharged by the above-mentioned dust outlet gate 11 after the negative pressure is turned off. In addition, a dust filtering member may be provided in the dust collection bin 102. The dust filtering member may be arranged outside the main suction port 103, so as to separate it from the dust collection inlet 105 in the dust collection bin 102, and prevent the small particle remaining materials from being sucked into the fan assembly 12 through the main suction port 103.

[0054] In addition, the shaping machine may further include a feeding bin 5 for feeding materials. The feeding bin 5 may include, for example, a main body that is generally cylindrical, and its lower vertical end includes a feeding hopper that is generally pyramidal or conical. The tip of the feeding hopper extends vertically downward and is provided with a feeding gate 4 to open or stop the feeding of materials. The feeding gate 4 is in communication with the material inlet 63 of the classification bin body 6 through devices such as pipes. In some embodiments, the discharge port of the shaping device 1 may be in communication with the material inlet 63 of the classification bin 6 by means of a bent pipe. And the feeding gate 4 may be connected to the side wall of a bent portion 69 that is inclined in the horizontal direction of the bent pipe. Thus, the materials entering the bent portion 69 will be blocked by the side wall of the lower pipe in the vertical direction and will not directly fall into the shaping device 1 due to their own weight.

[0055] In some embodiments, the above-mentioned fan assembly 12 may generate negative pressure, which may include negative pressure generating components such as a vacuum pump. The fan assembly 12 may be connected to the main suction port 103 of the dust collection bin 102 by means of a pipe, and the dust collection inlet 105 of the dust collection bin 102 is connected to the air flow outlet 61 of the classification bin body 6 by means of a pipe. The material inlet 63 of the classification bin body 6 is in communication with the discharge port 121 of the shaping device, and the discharge port 65 of the classification bin body 6 is connected to the feed port 120 of the shaping device by means of a pipe. Thus, the negative pressure generated by the fan assembly 12 can act on the inner cavity of the classification bin body 6 through the pipe and the inner cavity of the dust collection bin 102, and further jointly form a conveying air flow acting between the classification bin body 6 and the shaping device with the air flow driving assembly.

[0056] Specifically, refer to Figure 4。The air flow driving assembly may include a first main valve 9 disposed between the feed inlet 120 of the shaping device and the discharge port 65 of the classification bin body 6, and a throttle valve 2 and a second main valve 3 disposed between the discharge outlet 121 of the shaping device and the material inlet 63 of the classification bin body 6. The first main valve 9 and the second main valve 3 may be adjustable valves such as ball valves communicating with the atmosphere, and the throttle valve 2 may be an air flow adjustment valve capable of controlling the flow rate in the pipeline. By opening the first main valve 9 and the second main valve 3, the inside of the shaping machine can be communicated with the outside atmosphere, and the pressure drop between the negative pressure generated by the fan assembly 12 inside the shaping machine and the atmospheric pressure causes the air flow to blow into the pipeline and the inner cavity of the shaping machine.

[0057] Thus, by adjusting the opening and closing degrees of the first main valve 9, the second main valve 3 and the throttle valve 2, a local air pressure difference can be formed in the pipeline and the inner cavity between the shaping device and the classification bin body 6, so as to generate a directional conveying air flow. Similarly, the above-mentioned secondary blowing assembly 7 may also be an adjustable valve such as a ball valve communicating with the atmosphere, which generates an air pressure difference between the inside and the outside of the classification bin body 6 by communicating with the atmosphere, so as to provide an air flow for dispersing the material. In addition, the first main valve 9 may be disposed near the feed inlet 120 of the shaping device, so that the material entering the shaping device can be directly blown by the air flow, and the material can be fully dispersed in the shaping device.

[0058] Those skilled in the art can understand that although the above describes a setting for generating air flow using a valve communicating with the atmosphere, the present disclosure does not limit the specific generation method of the air flow. For example, the above-mentioned first main valve 9, second main valve 3 and secondary blowing assembly 7 may be changed to a first main pump, a second main pump and a secondary blowing pump, that is, an air pump is provided to supply air flow to the inside of the shaping machine. For another example, the fan assembly 12 may be changed to include an air pump that can access the first main valve 9, the second main valve 3 and the secondary blowing assembly 7 to provide a positive pressure air flow. As long as it can ensure that sufficient directional air flow can be generated in the shaping machine and there is sufficient filtration protection between the air flow generating assembly and the inside of the shaping machine.

[0059] During use, first, before the material enters the shaping machine, the fan assembly 12 and each air flow driving assembly can be started to generate a negative pressure in the classification bin body 6 and the dust collection bin 102, and a conveying air flow can be formed between the shaping device and the classification bin body 6. Then, the material can be put into the feeding bin 5, and the feeding gate 4 can be opened. By controlling the feeding speed of the material through the feeding gate 4, the material is put into the connecting pipeline between the shaping device and the classification bin body 6. At this time, due to the action of the conveying air flow, the fed material first enters the classification bin body 6 from the material inlet 63. The material is dispersed by the air flow blown out by the secondary blowing assembly 7 in the classification bin body 6, and is filtered and classified by means of the filter element 67 in the classification bin body 6 to discharge the capillary powder and small particles with unmatched particle sizes to the dust collector for collection.

[0060] Furthermore, the filtered large-particle materials fall into the discharge hopper 62 under their own weight and are discharged from the discharge port 65. The discharged materials first pass near the first main valve 9, and the airflow generated by the first main valve 9 can disperse the materials. The dispersed materials enter the shaping device through the feed port 120 of the shaping device. In the shaping device, the materials pass through the spheroidizing cavities 150 corresponding to the three hammer heads 131 in sequence. The materials are rotated and pulled by the hammers 130 in the spheroidizing cavities 150, and extrusion, friction, shearing, and collision occur between the materials, between the materials and the hammers 130, the transverse grinding columns 141, and the vertical grinding columns 140. The graphite particles are broken and extruded during this process. After multiple collisions, the large graphite particles gradually become ellipsoidal. During the collision process, the small particles are embedded into the large particles, making the large particles denser. Since the materials after shaping processing are denser and the cross-section shows fewer voids inside the materials, the tap density is significantly improved.

[0061] After the materials reach the discharge port 121, they are transported along the pipeline to the material inlet 63 of the classification bin 6 under the action of the conveying airflow, and are filtered and classified again in the bin, repeating the above classification and shaping process. At this time, the smaller particles in the materials have a smaller collision intensity and cannot combine with the large particles, so they can be separated in the classification bin 6 and discharged to the dust collector as tailings. The large-particle materials continue to be shaped in the shaper, and finally reach the finished product with the required particle size and tap density. By making corresponding settings for each gate, the fan assembly 12, and the airflow driving assembly, it can operate automatically, and the shaping duration can be adjusted. After the set shaping duration ends, the materials can be automatically discharged by the main discharge gate 16 to obtain the finished product.

[0062] In this process, the large particles continuously repeat the process of shaping in the shaping device → screening in the classification bin → shaping in the shaping device → screening in the classification bin. The material particles are continuously compacted, and finally reach the required tap density. After the materials are purified, they are coated with asphalt and carbonized. While the tap density increases, the specific surface area decreases more significantly than that of normal products, and the cycle performance of the produced finished products is better than that of conventional products.

[0063] According to the relevant process flow of graphite treatment, when producing various modified graphite products, natural flake graphite must first be crushed and spheroidized. See Figure 6 - Figure 8c , Figure 6 shows the SEM image of the flake graphite raw material at a magnification of 500 times; Figure 7a shows the SEM image of the crushed graphite particles at a magnification of 500 times; Figure 7b shows the SEM image of the crushed graphite particles at a magnification of 1000 times; Figure 7c shows the SEM image of the crushed graphite particles at a magnification of 2000 times;Figure 8a An electron microscope image of spheroidized graphite particles shaped by a shaping machine according to some embodiments of the present disclosure at a magnification of 500 times is shown; Figure 8b An electron microscope image of spheroidized graphite particles shaped by a shaping machine according to some embodiments of the present disclosure at a magnification of 1000 times is shown; Figure 8c An electron microscope image of spheroidized graphite particles shaped by a shaping machine according to some embodiments of the present disclosure at a magnification of 2000 times is shown.

[0064] After testing, graphite particle materials with an input particle size of D50 of 15 - 20 μm after crushing enter the shaping machine. After the shaping time set by the system ends, for particles with D50 = 15 - 25 μm, after shaping, D90 / D10 ≤ 2.5, the tapped density of the material can be increased to ≥ 0.93, the material yield is increased by 30% compared to the existing processes in the current market, and the single product yield can be increased to ≥ 80%. Moreover, the tailings can be continuously shaped by the equipment to produce other small-particle-size products, and the conversion yield of the tailings is generally ≥ 50%. The combined total material utilization rate can reach more than 90%. After purification, the carbon content of the semi-finished material is increased from 95% to 99.95%. The raw materials: pitch = 9:1 are coated and carbonized. After making the finished product, for particles with D50 = 15 - 25 μm, the tapped density is increased to ≥ 1.1, the specific surface area is reduced to ≤ 3, the magnetic substances and trace elements are normal, the test data of the finished product performance indicators are normal, and the capacity and cycle performance are better.

[0065] When graphite particle materials with an input particle size of D50 of 8 - 15 μm after crushing enter the shaping machine, and after the shaping time set by the system ends, for particles with D50 = 8 - 18 μm, after shaping, D90 / D10 ≤ 2.5, the tapped density of the material can be increased to ≥ 0.85, the material yield is increased by 20% compared to the existing processes in the current market, and the single product yield can be increased to ≥ 60%. Moreover, the tailings can be continuously shaped by the equipment to produce other small-particle-size products, and the conversion yield of the tailings is generally ≥ 50%, and the combined total material utilization rate can reach more than 80%. After purification, the carbon content of the semi-finished material is increased from 95% to 99.95%. The raw materials: pitch = 88.5:11.5 are coated and carbonized. After making the finished product, for particles with D50 = 8 - 18 μm, the tapped density is increased to ≥ 1.1, the specific surface area is reduced to ≤ 3.5, the magnetic substances and trace elements are normal, the test data of all indicators of the finished product performance indicators are normal, and the capacity and cycle performance are better.

[0066] With the shaping machine according to the embodiments of the present disclosure, through single-machine cyclic shaping, the shaping device is configured to include one or more hammer discs, so that while the material is moving, it collides with hammers, vertical grinding columns, etc., and mutual collisions between materials occur in the spheroidization cavity, shaping in a manner of high shaping intensity, enabling flaky materials to form balls in a short time, greatly shortening the entire process, and obtaining higher productivity, yield, and higher tapped density. It can achieve the effect of replacing multiple devices with a single machine to improve the tapped density, while improving the overall yield, enhancing the coating performance of the surface material of the semi-finished product, and achieving the purpose of reducing the specific surface area of the finished product. The graphite products produced by the shaping machine can break the trend of change between particle size and specific surface area tapped density, can produce spherical graphite with wide particle size and high tapped density, and have a high yield. The graphite particles are denser than those of the traditional process, and the particle surface has better coating properties.

[0067] Compared with the traditional process, when the asphalt proportion is the same, it can obtain products with a smaller specific surface area, and the produced finished products have obvious advantages in cycle performance, charge and discharge efficiency, etc. At the same time, when producing finished products with a fixed asphalt value, it can produce finished products with a specific surface area close to the lower limit, greatly improving the flexibility of semi-finished product processing, reducing the amount of asphalt used in making finished products, and reducing the asphalt cost. After the material is coated, the specific surface area decreases significantly, the first efficiency of the finished product is better than that of the normal product with coating, and the cycle performance is more prominent, and the other indicators are equivalent to those of the normal product. At the same time, since the use of multiple series-connected devices for processing is avoided, the overall equipment cost and maintenance cost are significantly reduced, saving production space, manpower and material resources.
