Abstract

This invention discloses a ceramic ball mill, relating to the field of ball mill technology, specifically a ceramic ball mill comprising a ball mill body. Multiple non-connected inner plates are evenly hinged to the inner circumferential surface of the ball mill body, and each inner plate forms a temporary storage chamber for temporary material storage between itself and the inner circumferential surface of the ball mill body. Through the coordinated arrangement of the inner plates, temporary storage chambers, telescopic components, and filter ports, timely screening, temporary storage, and periodic recirculation of qualified fine materials can be achieved. This effectively eliminates the "buffer layer" formed by qualified fine materials from hindering the contact between the grinding balls and coarse particles, preventing over-grinding of qualified materials.

Description

Technical Field

[0001] This invention relates to the field of ball mill technology, and more specifically, to a ceramic ball mill. Background Technology

[0002] As a high-efficiency and energy-saving ball mill with wear-resistant ceramic liners as its core functional component, the ceramic ball mill is widely used in material mixing and fine grinding operations in various industries such as mineral processing, building ceramics, non-metallic mineral processing, and chemical raw material processing due to its unique structural design and adaptability to working conditions. The core working unit of the equipment, the cylinder, adopts a multi-compartment segmented design. Each compartment is equipped with high-strength wear-resistant ceramic liners and high-alumina grinding balls. The cylinder is rotated by an external gear driven by a motor. The dry grinding or wet grinding operation mode can be flexibly switched according to the material characteristics and processing requirements. At the same time, the fineness of the product can be precisely controlled by changing different types of ceramic liners and precisely adjusting the grinding time. Its core working principle is that during operation, the crushed ore and grinding balls inside the cylinder are gradually lifted to a certain height by the combined action of the friction force on the liner surface and the centrifugal force of the cylinder. When the force is insufficient to balance its own weight, the material and grinding balls will fall along a parabolic trajectory or cascade down the liner surface. During this process, the ore to be ground is subjected to the violent impact of the grinding balls and the squeezing and grinding action between the material and between the grinding balls and the liner, and is gradually crushed to the target fineness, thus completing the grinding process. However, existing traditional ceramic ball mills still have significant technical shortcomings in actual operation, which seriously affect processing efficiency and ease of use. Firstly, the low grinding efficiency is a significant problem. The single rotational motion of the cylinder can only cause the material inside the cylinder to tumble after rising to a certain height. However, the material at the bottom of the cylinder, affected by factors such as compression from the material above and its own gravity, needs to rotate synchronously with the cylinder to a certain height before it can tumble and participate in the core grinding processes such as impact and compression grinding. It is in a passive waiting state. This passive participation in grinding significantly reduces the effective interaction frequency between the material and the grinding balls, resulting in a clear efficiency bottleneck in the grinding process. Ultimately, this leads to low overall grinding efficiency of the equipment, high energy consumption, and high processing costs. Secondly, the effectiveness and uniformity of material grinding are insufficient. For the grinding effect of ball mills, the effective collision frequency between the material and the grinding balls, the concentration of grinding energy, and the uniformity of material dispersion within the cylinder are the three core influencing factors. However, existing equipment generally lacks an effective material classification and dynamic separation mechanism. Qualified materials that have been crushed to the target fineness cannot be separated and discharged from the grinding system in a timely manner. They will still circulate within the cylinder and participate in the grinding operation along with coarse particles that have not met the particle size requirements. This phenomenon not only significantly reduces the effective collision probability between coarse particles and grinding balls, but also forms a "buffer layer" in the cylinder, hindering direct contact between the balls and coarse materials. This makes it take longer for the coarse materials to complete grinding and may also cause over-grinding of qualified materials. This wastes energy, easily leads to uneven particle size distribution in the product, affects product quality stability, and significantly prolongs the overall processing cycle, causing many inconveniences for operators in production scheduling and efficiency management. For example, in the continuous ball mill for ceramics with application number 202210415592.8, although the prior art has a linkage between the lateral reciprocating movement and vertical rotation of the processing tank relative to the support sleeve, and several steel balls crush the material in the processing tank when the processing tank rotates relative to the support sleeve, and at the same time, the processing tank moving laterally relative to the support sleeve can make the feed inlet intermittently align with the discharge inlet to achieve the effect of periodically adding material to the processing tank and ensuring the continuity of material addition into the processing tank, the material and the balls still undergo an orderly tumbling when the processing tank rotates, so the crushing effect and time are not ideal.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 For the grinding effect of ball mills, the effective collision frequency between the material and the grinding balls, the concentration of grinding energy, and the uniformity of material dispersion within the mill are the three core influencing factors. However, existing equipment generally lacks an effective material classification and dynamic separation mechanism. Qualified materials that have been crushed to the target fineness cannot be separated and discharged from the grinding system in a timely manner. They will still circulate within the mill along with coarse particles that have not met the particle size requirements, participating in the grinding operation. This phenomenon not only significantly reduces the effective collision probability between coarse particles and the grinding balls, but also causes qualified fine materials to form a "buffer layer" within the mill, hindering direct contact between the balls and coarse materials. This makes it take longer for the coarse materials to complete grinding and may also cause over-grinding of qualified materials, wasting energy and easily leading to uneven product particle size distribution, affecting product quality stability. At the same time, it significantly extends the overall processing cycle, causing many inconveniences for operators in production scheduling and efficiency management. To solve the above problems, this embodiment is invented.

[0018] Please see Figures 1 to 7This invention provides a technical solution: a ceramic ball mill, including a ball mill body 1. The ball mill body 1 is a relatively mature conventional core structure in the prior art. Its core working mechanism of material crushing based on media impact and grinding is well known to those skilled in the art and has been fully disclosed in relevant technical documents and product manuals. Therefore, its specific working principle will not be described in detail. Multiple inner plates 3 that are not connected end to end are evenly hinged on the inner circumferential surface of the ball mill body 1. Each inner plate 3 and the inner circumferential surface of the ball mill body 1 form a temporary storage chamber for temporary material storage. One end of the inner plate 3 is provided with a telescopic component that can open or close the temporary storage chamber by its own gravity. Multiple filter ports 5 are evenly opened on the side of the multiple inner plates 3 away from the inner circumferential surface of the ball mill body 1. Multiple stirring columns 17 that can rotate synchronously with the inner plates 3 are provided inside the ball mill body 1. Multiple stirring rods 12 that can cause the corresponding inner plates 3 to shake are evenly fixedly connected to the outer circumferential surface of the stirring columns 17. The filter port 5 forms a connecting channel between the temporary storage chamber and the grinding space inside the ball mill body 1. Its core function is based on the technical principle of material classification and particle size screening. When the ball mill body 1 is working, the material inside the cylinder is gradually refined under the impact and grinding action of the grinding balls. When the material particles reach the target fineness, their particle size can match the aperture specification of the filter port 5, and then quickly enter the temporary storage chamber formed by the inner plate 3 and the inner circumferential surface of the ball mill body 1 for temporary storage. This design can promptly separate qualified fine materials from the grinding system and prevent them from being trapped in the cylinder. The continuous internal circulation eliminates the "buffer layer" formed by qualified fine materials from hindering the contact between the grinding balls and coarse particles. On the other hand, based on the principle of particle collision dynamics, it reduces the dispersion and consumption of grinding energy by fine materials, making the grinding energy more concentrated on the substandard coarse particles. This significantly increases the effective collision frequency and intensity between coarse particles and grinding balls. Finally, through the synergistic effect of the filter port 5 and the temporary storage chamber, the grinding cycle of coarse particles is effectively shortened. While avoiding over-grinding of qualified materials, it improves the overall efficiency and energy utilization of the grinding operation.

[0019] Please see Figure 1 A drive motor is located on the right side of the ball mill body 1. A pulley is fixedly connected to the drive shaft of the drive motor, and a belt is fitted around the pulley and the middle of the outer circumference of the ball mill body 1. Therefore, when the drive motor starts running, it can directly drive the drive shaft to rotate around its axis. During the rotation of the drive shaft, the pulley is driven to move in tandem with it. With the help of the belt transmission, the driving force can be stably transmitted to the ball mill body 1, thereby driving the ball mill body 1 to achieve smooth rotation.

[0020] Please see Figures 1 to 7Multiple inclined support plates 2 are uniformly fixedly connected to the inner circumferential surface of the ball mill body 1. The end of the inclined support plate 2 away from the inner circumferential surface of the ball mill body 1 is slidably mounted on the inner plate 3. Two arc-shaped support plates 23 are fixedly connected to the end of the inclined support plate 2 near the inner plate 3. The opposite surfaces of the two arc-shaped support plates 23 are both attached to the inner plate 3. A limiting guide block with one end slidably connected inside the inner plate 3 is fixedly connected to the side of the two arc-shaped support plates 23 that are attached to the inner plate 3. Limiting guide grooves adapted to the limiting guide blocks are opened on both sides of the inner plate 3 that are attached to the two arc-shaped support plates 23. Through the sliding cooperation between the limiting guide blocks and the limiting guide grooves, one end of the inner plate 3 can be stably pressed tightly against the inclined support plate 2, thereby realizing the stable rotation of the inner plate 3 around one end of the inclined support plate 2.

[0021] Please see Figures 1 to 7 The inner plate 3 has a first mounting groove 9 at one end near the inclined support plate 2. The inclined support plate 2 is fixedly connected to a limiting plate 10 at one end near the inner plate 3. The end of the limiting plate 10 away from the inclined support plate 2 is slidably connected in the first mounting groove 9. Limiting grooves 22 are opened on both the front and rear sides of the first mounting groove 9. A limiting slider 21 with one end slidably connected in the limiting groove 22 is fixedly connected to both the front and rear ends of the limiting plate 10. A plurality of first springs 8 with one end set on the inner side of the first mounting groove 9 are fixedly connected to the side of the limiting plate 10 away from the inner circumferential surface of the ball mill body 1. Meanwhile, through the coordinated operation of the limiting plate 10, the limiting slider 21 and the limiting groove 22, the stability of the inner plate 3 during rotation can be significantly improved. When the external force causes the inner plate 3 to rotate around the inclined support plate 2 towards the inner circumference of the ball mill body 1, since the limiting plate 10 and the limiting slider 21 are both fixed to the inclined support plate 2 and remain stationary, the sliding constraint between them and the limiting groove 22 will cause multiple first springs 8 to undergo compression deformation. When the external force is removed, the first springs 8 will release the stored elastic potential energy, thereby driving the inner plate 3 to return to the initial position.

[0022] Please see Figures 1 to 7 The telescopic component includes a first rotating shaft 20 rotatably connected to the end of the inner plate 3 away from the inclined support plate 2, and an auxiliary blocking barrel 13 fixedly connected to the first rotating shaft 20. The auxiliary blocking barrel 13 is provided with a second baffle 16 at the end away from the inner plate 3, which can abut against the inner circumferential surface of the ball mill body 1. An auxiliary connecting plate 15 is fixedly connected to one end of the second baffle 16 near the inner plate 3. The end of the auxiliary connecting plate 15 away from the second baffle 16 is slidably connected to the inside of the auxiliary blocking barrel 13. A second spring 14 is fixedly connected to one end of the auxiliary connecting plate 15 away from the second baffle 16. The end of the second spring 14 away from the auxiliary connecting plate 15 is fixedly connected to the inner side of the auxiliary blocking barrel 13. When the ball mill body 1 starts and rotates around its axis, since multiple inclined support plates 2 are fixedly connected to the inner circumferential surface of the ball mill body 1, and the inner plate 3 is assembled on the inclined support plate 2 through the sliding cooperation of the limiting guide block and the limiting guide groove, the inclined support plate 2 will drive the inner plate 3 to move in a circular motion synchronously with the ball mill body 1. The telescopic components (including the first rotating shaft 20, the auxiliary blocking barrel 13, the auxiliary connecting plate 15, the second baffle 16 and the second spring 14) are the matching components of the inner plate 3 at the end away from the inclined support plate 2, and will also participate in the circular motion along with the inner plate 3. Based on the synergistic mechanism of gravitational potential energy and mechanical motion, when the ball mill body 1 continues to rotate, the free end of the auxiliary blocking barrel 13 will adaptively rotate around the first rotating shaft 20 due to the dynamic change of its own gravitational torque. Specifically, when a certain inner plate 3 rotates with the ball mill body 1 to the lowest position closest to the ground, the gravity of the auxiliary blocking barrel 13, the gravity of the second baffle 16 and the gravity of the auxiliary connecting plate 15 form a resultant force in the same direction. This resultant force is transmitted to the end of the inner plate 3 through the first rotating shaft 20, causing the auxiliary blocking barrel 13 to rotate towards the opening of the temporary storage chamber until the second baffle 16 is tightly attached to the inner circumferential surface of the ball mill body 1 under the elastic pre-tightening force of the second spring 14, thereby completely sealing the opening of the temporary storage chamber. This can effectively prevent unfiltered mixed materials in the ball mill body 1 from accidentally entering the temporary storage chamber from the opening, ensuring that the temporary storage chamber only receives qualified fine materials screened by the filter port 5. As the ball mill body 1 continues to rotate, the inner plate 3 gradually moves from the low position area to the high position area away from the ground. At this time, the direction of the gravitational torque on the auxiliary blocking barrel 13, the auxiliary connecting plate 15 and the second baffle 16 changes in opposite directions, and the centrifugal force generated by the rotation of the ball mill body 1 gradually weakens the constraint effect on the telescopic component. Under the motion trend dominated by the gravitational torque, the auxiliary blocking barrel 13 will rotate around the first rotating shaft 20 in the direction away from the opening of the temporary storage chamber, and finally realize the complete opening of the temporary storage chamber. At this time, the qualified fine material that has entered the temporary storage chamber through the filter port 5 and is temporarily stored thereby will be discharged smoothly from the opening and fall back into the core grinding space of the ball mill body 1 under the combined action of its own gravity and the inertial force generated by the rotation of the ball mill body 1. It will then participate in the subsequent grinding operation together with the non-compliant coarse particles to ensure that all materials can undergo a complete and uniform grinding cycle. After the entire batch of materials reaches the target fineness, they will be discharged uniformly through the discharge port on the circumference of the ball mill body 1 to achieve the homogenization grinding and centralized collection of the batch of materials. As the inner plate 3 continues to rotate with the ball mill body 1, after passing the highest position area far from the ground, it will move towards the ground again. According to the constraint mechanism of the material movement trajectory, the maximum rotation angle of the auxiliary blocking barrel 13 when opening the temporary storage chamber is designed to be less than 90 degrees. Therefore, it can be ensured that the movement trajectory of the auxiliary blocking barrel 13 is always outside the opening of the temporary storage chamber during the process of falling back to the lower position area. Before the auxiliary blocking barrel 13, the auxiliary connecting plate 15 and the second baffle 16 come into contact with the unscreened mixture inside the ball mill body 1, the gravitational torque has driven the auxiliary blocking barrel 13 to complete the reset rotation. Combined with the elastic reset force of the second spring 14, the second baffle 16 will once again tightly fit the inner circumferential surface of the ball mill body 1 and re-close the opening of the temporary storage chamber. Simultaneously, through a dynamic control mechanism of "screening-temporary storage-periodic reflux," the industry pain point of continuous accumulation of qualified fine materials forming a "buffer layer" in traditional grinding processes is fundamentally solved. The qualified fine materials screened through filter port 5 do not remain in the core grinding space indefinitely, but first enter a temporary storage chamber for temporary storage. Then, through the periodic opening and closing of the telescopic components (first rotating shaft 20, auxiliary blocking barrel 13, auxiliary connecting plate 15, second baffle 16, and second spring 14), orderly reflux is achieved. The temporary storage function of the temporary storage chamber effectively controls the instantaneous concentration of fine materials in the grinding space, preventing excessive accumulation that would hinder direct contact between the grinding balls and coarse particles, significantly improving the interaction between coarse particles and grinding balls. The effective collision frequency and intensity, along with the phased separation of fine materials from the high-energy grinding zone, completely avoid the problem of over-grinding caused by continuous participation in grinding. In addition, periodic recirculation ensures that the entire batch of materials can undergo a complete grinding cycle simultaneously, effectively avoiding the situation of some materials being under-ground or over-ground. Finally, through the coordinated linkage of the telescopic component with the inner plate 3 and the inclined support plate 2, it not only solves the dual technical problems of "buffer layer hindering contact" and "over-grinding of qualified fine materials" in traditional grinding, but also ensures the uniformity of particle size distribution of the entire batch of products, greatly improving the overall efficiency and energy utilization of grinding operations, and meeting the high-efficiency and homogenization development needs of modern grinding equipment in batch processing scenarios.

[0023] Example 2 Although the above embodiments achieve orderly reflux through the periodic opening and closing of the telescopic components (first rotating shaft 20, auxiliary blocking barrel 13, auxiliary connecting plate 15, second baffle 16, and second spring 14), and effectively control the instantaneous concentration of fine materials in the grinding space through the temporary storage function of the temporary storage bin, thus avoiding excessive aggregation that would hinder the direct contact between the grinding balls and coarse particles, and significantly improving the effective collision frequency and intensity of coarse particles and grinding balls, the single rotational motion of the ball mill body 1 can only cause the material inside the ball mill body 1 to overturn after rising to a specific height. The material at the bottom of the cylinder is subject to a combination of factors, including pressure from the material above and its own gravity. It needs to rotate synchronously with the cylinder to a specific height before it can tumble and participate in the core grinding processes such as impact, compression, and grinding. The material is in a passive waiting state. This passive participation in grinding significantly reduces the effective interaction frequency between the material and the grinding balls, resulting in a clear efficiency bottleneck in the grinding process. Ultimately, this leads to low overall grinding efficiency, high energy consumption, and high processing costs. This embodiment is invented to solve the above problems.

[0024] Please see Figures 1 to 7 Based on the above embodiments, the technical solution adopted includes a plurality of quarter-ball blocks 6 fixedly connected to the side of the inner plate 3 away from the inner circumferential surface of the ball mill body 1; a plurality of support rods 11 fixedly connected to the side of each arc-shaped support plate 23 away from the inner circumferential surface of the ball mill body 1; a second rotating shaft 19 rotatably connected to one end of two corresponding support rods 11 away from the arc-shaped support plate 23; and a plurality of stirring columns 17 are respectively fixedly connected to the corresponding second rotating shaft 19. Therefore, when the inclined support plate 2 drives the arc-shaped support plate 23 to rotate synchronously with the ball mill body 1, the rigid transmission action of the support rods 11 can drive the first The second rotating shaft 19 moves in a circular motion along with the arc-shaped support plate 23. At the same time, since the second rotating shaft 19 and the support rod 11 adopt a rotating connection structure, the second rotating shaft 19 can rotate independently relative to the support rod 11 around its own axis while completing the circular motion with the support rod 11. Through the fixed connection between the shaft of the second rotating shaft 19 and the stirring column 17, the stirring column 17 is synchronously driven to rotate coaxially around its own axis. As the stirring column 17 rotates around its own axis, it will synchronously drive the multiple stirring rods 12 evenly distributed on its outer peripheral wall to rotate in a coordinated manner, thereby realizing the dynamic stirring effect on the material in the grinding chamber. A support frame is provided directly below the ball mill body 1. Bearing seats with driven shafts are installed at both the front and rear ends of the support frame. The front and rear ends of the ball mill body 1 are respectively fixedly connected to the corresponding driven shafts. A limiting shaft 25 is rotatably connected at the axis of the first driven shaft from front to back. The rear end of the limiting shaft 25 extends into the ball mill body 1. An auxiliary limiting column 24 is fixedly connected to the rear end of the limiting shaft 25. An arc-shaped rack 4 is fixedly connected to the bottom end of the auxiliary limiting column 24. A fixing plate 26 with one end set on the limiting shaft 25 is fixedly connected to the front end of the support frame. A drive gear 18 with its outer circumferential surface meshing on the arc-shaped rack 4 is fixedly connected to the front end of a plurality of second rotating shafts 19. Therefore, when the ball mill body 1 starts and rotates around its axis, the fixed plate 26 rigidly limits the limiting shaft 25, restricting the rotational freedom of the limiting shaft 25 around its own axis. Thus, it will not rotate synchronously with the driven shaft of the ball mill body 1. The auxiliary limiting column 24, which is fixedly connected to the limiting shaft 25, remains stationary. As a result, the arc-shaped rack 4, which is fixed to the bottom of the auxiliary limiting column 24, maintains a fixed posture through the rigid support of the limiting shaft 25 and remains stationary. When the second rotating shaft 19 moves in a circular motion synchronously with the inner plate 3 under the rigid transmission action of the support rod 11, the stationary arc-shaped rack 4 and the drive gear 18 that moves in a circular motion with the second rotating shaft 19 form a relative meshing motion, thereby forcing the drive gear 18 to rotate around its own axis. Through the fixed connection relationship with the second rotating shaft 19, the drive gear 18 transmits the rotational motion synchronously to the second rotating shaft 19, causing the second rotating shaft 19 to obtain an additional independent rotational motion around its own axis on the basis of moving in a circular motion with the support rod 11. Under the synergistic effect of this dual motion, the second rotating shaft 19 synchronously drives the stirring column 17 fixedly connected thereto and a plurality of stirring rods 12 evenly distributed on the outer peripheral wall of the stirring column 17 to perform compound motion. During the rotation process, the plurality of stirring rods 12 can actively disturb the material at the bottom of the ball mill body 1, breaking the relatively static state of the bottom material formed by compression and stacking and gravity constraint in traditional grinding, and causing the material that was originally passively waiting for the cylinder to drive the tumbling to produce lateral diffusion and longitudinal tumbling motion. This increases the effective contact probability and collision frequency between the grinding balls and material particles in three-dimensional space, while enabling the grinding energy to be transferred to the material particles more evenly and efficiently. Based on the energy transfer efficiency optimization theory, it avoids the waste caused by the concentration of grinding energy in a local area, significantly improving the effective grinding efficiency of the material per unit time. Ultimately, it not only achieves a significant improvement in grinding effect, but also accelerates the material crushing rate and increases the target particle size compliance rate. Furthermore, it optimizes the uniformity of product particle size distribution, reduces energy consumption and processing costs, and effectively breaks through the efficiency bottleneck of passive grinding of materials at the bottom of traditional ball mills. Furthermore, during the compound rotational motion of the stirring rod 12 around the second rotating shaft 19, the quarter ball block 6 fixed on the inner plate 3 is precisely matched with the rotation trajectory of the stirring rod 12. When the free end of the stirring rod 12 moves away from the stirring column 17 to the area where the quarter ball block 6 is located, it will form a rigid contact with the arc-shaped surface of the quarter ball block 6, thereby generating a thrust along the tangential direction of the quarter ball block 6. This driving force is directly driven by the rigid transmission of the quarter ball block 6 to rotate the inner plate 3 around the contact end of the inclined support plate 2, so that the temporary storage space between the inner plate 3 and the inner circumferential surface of the ball mill body 1 undergoes adaptive deformation. When the free end of the stirring rod 12 continues to rotate and passes the highest point of the quarter ball block 6, the first spring 8, which was previously compressed due to the rotation of the inner plate 3, will quickly release the stored elastic potential energy, forming an instantaneous reset impact force, driving the inner plate 3 to swing back quickly and return to the initial position, thus forming a "push-reset" cycle process. This allows the inner plate 3 to obtain high-frequency reciprocating shaking and micro-vibration effects while following the ball mill body 1 in a circular motion. Therefore, the shaking of the inner plate 3 can break the relative static state of the material particles near the filter port 5, accelerate the migration rate of qualified particles that have reached the target fineness to the filter port 5, and significantly improve their screening efficiency as they pass through the filter port 5 and enter the temporary storage chamber. At the same time, the micro-vibration of the inner plate 3 can generate periodic mechanical impacts, effectively breaking the adsorption force between the material particles and the inner wall of the filter port 5 and the agglomeration force between particles, reducing the probability of particles being stuck and blocked in the filter port 5 from the root, and ensuring the smooth flow of the screening channel. Meanwhile, the auxiliary connecting plate 15 and the auxiliary blocking barrel 13 adopt a sliding connection structure, which allows the auxiliary connecting plate 15 to adaptively slide along the internal cavity of the auxiliary blocking barrel 13 when the inner plate 3 reciprocates. With the elastic pre-tightening force compensation of the second spring 14, the contact pressure between the second baffle 16 and the inner circumferential surface of the ball mill body 1 can be adjusted in real time. Even if the inner plate 3 is in a dynamic shaking state, the auxiliary blocking barrel 13, the auxiliary connecting plate 15 and the second baffle 16 can still maintain an effective seal on the opening of the temporary storage chamber through the dual effects of sliding adaptation and elastic buffering, preventing unfiltered coarse particles from accidentally entering the temporary storage chamber, ensuring the stability and reliability of the "screening-temporary storage" mechanism, and realizing the coordinated unity of vibration-enhanced screening of the inner plate 3 and sealing protection of the temporary storage chamber.

[0025] Multiple first baffles 7 are fixedly connected to one end of the inclined support plate 2 away from the inner circumferential surface of the ball mill body 1, and a flow gap adapted to the particle size of the material is reserved between two adjacent first baffles 7. The size of the gap can ensure the smooth passage of the material during the grinding process and effectively block the grinding stones. Therefore, when the inclined support plate 2 rotates synchronously with the ball mill body 1, the material in the cylinder can continuously flow downward from the gap between two adjacent first baffles 7 under the combined action of gravity and the rotational inertia of the cylinder, ensuring the circulation flow of the material in the grinding chamber. However, the grinding stones, because their particle size is larger than the gap size, will have their movement trajectory restricted by the blocking structure formed by the first baffles 7, and cannot fall down from the gap with the material. They can only continue to rise with the inclined support plate 2. As the ball mill body 1 continues to rotate, the inclined support plate 2 drives the blocked grinding balls to gradually rise to the preset height area at the top of the ball mill body 1. At this time, the gravitational potential energy of the grinding balls reaches its peak. When the component of the gravity of the grinding balls along the tangent of the inclined support plate 2 is greater than the blocking constraint force of the first baffle 7, the grinding balls will, under the dominant action of their own gravity, pass over the top of the first baffle 7 and break away from the support of the inclined support plate 2. They will then impact the material pile below from a high place by free fall or throwing. In this process, the gravitational potential energy of the grinding balls is efficiently converted into kinetic energy, forming a strong impact crushing effect. According to the principle of impact mechanics, the instantaneous impact force generated by this high-level impact can directly act on the internal cracks of the material particles, causing the particles to be crushed and refined quickly. Compared with the squeezing and grinding effect generated by the natural rolling of grinding balls in traditional ball mills, its crushing efficiency and grinding intensity are significantly improved. Meanwhile, the uniform arrangement of the first baffle 7 allows the grinding balls to be lifted to different heights in batches and areas before being dropped sequentially, creating a continuous impact effect with multiple points and frequencies. This avoids the problem of concentrated or unevenly distributed impact energy caused by dropping from a single height. Therefore, it not only significantly increases the effective impact energy between the grinding balls and material particles, but also breaks up the agglomeration of the material pile, causing the material particles to redistribute under the impact, further improving the uniformity of contact between the material and the grinding balls in the subsequent grinding process. Finally, through the synergistic effect of the first baffle 7 and the inclined support plate 2, the impact energy of the grinding balls is optimized, effectively solving the technical pain points of the single grinding method and limited crushing efficiency in traditional ball mills. This significantly improves the overall crushing efficiency and material refinement effect of the grinding operation, aligning with the development trend of high-efficiency and energy-saving industrial equipment.

[0026] In summary, when using this ceramic ball mill, the drive motor on the right side of the ball mill body 1 is started first. The drive shaft of the drive motor drives the pulley to drive the drive force to be stably transmitted to the ball mill body 1 through belt transmission, so that the ball mill body 1 can achieve smooth rotation. As the ball mill body 1 rotates, the inclined support plates 2 evenly distributed inside it move in a circular motion. On the one hand, the first baffle 7 at the end of the inclined support plate 2 away from the inner circumference of the ball mill body 1 will effectively block the grinding stones, allowing the material to pass smoothly through the matching gap between the adjacent first baffles 7. The grinding stones are driven to rise to the preset height at the top of the cylinder and fall over the first baffle 7 under the action of gravity, converting the gravitational potential energy into kinetic energy to impact the material pile, thereby enhancing the impact crushing effect. On the other hand, the inclined support plate 2 drives the inner plate 3 to move synchronously through the cooperation of the arc support plate 23, the limiting guide block and the limiting guide groove. At the same time, with the help of the limiting plate 10, the limiting slider 21 and the first spring 8, the stability of the movement of the inner plate 3 is ensured. At the same time, the fixed plate 26 on the support frame below the ball mill body 1 forms a rigid limit on the limiting shaft 25, so that the arc-shaped rack 4 at the bottom of the auxiliary limiting column 24 remains stationary. When the second rotating shaft 19 follows the inner plate 3 in a circular motion under the transmission of the support rod 11, the drive gear 18 at the front end of the second rotating shaft 19 meshes with the stationary arc-shaped rack 4 to generate rotation, which in turn drives the stirring column 17 and the stirring rod 12 on the outer periphery to perform a compound rotational motion. The stirring rod 12 can not only actively disturb the material at the bottom of the ball mill body 1 and break its passive accumulation state, but also rigidly resist the quarter ball block 6 on the inner plate 3, pushing the inner plate 3 to rotate around the inclined support plate 2. After the stirring rod 12 passes the quarter ball block 6, the first spring 8 releases elastic potential energy to drive the inner plate 3 to quickly reset, forming a high-frequency reciprocating oscillation. The shaking of the inner plate 3 accelerates the migration of qualified fine materials to the filter port 5, improving the efficiency of fine material screening into the temporary storage chamber. It also breaks up particle adsorption and agglomeration through micro-vibration, preventing the filter port 5 from clogging. The telescopic components at one end of the inner plate 3 (first rotating shaft 20, auxiliary blocking barrel 13, auxiliary connecting plate 15, second baffle 16 and second spring 14) realize the periodic opening and closing of the temporary storage chamber opening based on the dynamic changes of gravitational torque and centrifugal force. When the position is low, the second baffle 16 closes the opening under the action of gravity and the second spring 14, ensuring that only qualified fine materials enter the temporary storage. When the position is high, the opening opens, and the fine materials flow back to the grinding space under the action of gravity and inertial force, completing the dynamic control of screening-temporary storage-periodic return.

[0027] Throughout the entire process, all components work together in tandem. The first baffle 7 enhances the impact crushing capability of the grinding balls, while the combined motion of the stirring rod 12 improves the uniformity of material dispersion. Furthermore, the cooperation of the inner plate 3, the filter port 5, and the telescopic components solves the problems of a "buffer layer" for qualified fine materials and over-grinding. Ultimately, this significantly improves the effective collision frequency between the material and the grinding balls, the concentration of grinding energy, and the uniformity of product particle size, greatly shortens the processing cycle, reduces energy consumption, and fully meets the requirements of high efficiency, homogenization, and energy saving in modern batch grinding operations.
