Description

Technical Field

[0001] This invention relates to the field of quartz sand processing technology, specifically a ball mill for manufacturing quartz sand powder. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. It is typically milky white or colorless and translucent. As a hard, wear-resistant, and chemically stable silicate mineral, it is widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical solvents, metallurgy, construction, and chemical industries. After mining, quartz stone undergoes structural crushing using designated equipment to produce quartz sand particles with smaller compressive mass. These particles then undergo a grinding process to ultimately convert large pieces of quartz stone into usable quartz powder.

[0003] Chinese patent application CN202311467130.1 discloses a ball mill for crushing quartz sand raw materials, including a central housing with an upper cover on top. The central housing contains a combined processing mechanism, and the upper cover has an airflow induced mechanism on top. The combined processing mechanism includes an inner sleeve, with a first bearing fixedly installed on its inner wall. A first linkage rod is fixedly inserted into the inner wall of the first bearing's inner shaft. An assembly base is fixedly fitted onto the outer wall of the first linkage rod, and a set of pneumatic pressure rods is fixedly installed on the bottom of the inner wall of the assembly base. Each pneumatic pressure rod has an external plate fixedly installed on its top and shaft end. However, this patent cannot ensure sufficient contact between the material and the medium in every part of the quartz processing process. The impact force of the medium on the material is relatively fixed, which can damage the equipment's lifespan over time.

[0004] However, existing ball mills for manufacturing quartz sand powder still have some problems in actual use. Because the force generated when the material collides with the media is relatively limited, it cannot be ensured that the material in each part can fully contact the media during the quartz processing. The impact force of the media on the material is relatively fixed, which damages the life of the equipment after long-term use. Under the condition of large centrifugal force, the impact angle and force of the media on the liner will increase, resulting in faster wear of the liner. At the same time, the irregular movement of the media leads to insufficient and uneven grinding of the material. Summary of the Invention

[0005] The purpose of this invention is to provide a ball mill for manufacturing quartz sand powder, which solves the problems of poor grinding effect and uneven and insufficient grinding of quartz sand mentioned in the background art.

[0006] This invention is achieved through the following technical solution: a ball mill for manufacturing quartz sand powder, comprising:

[0007] A grinding cylinder, which is cylindrical in shape and has a grinding space inside;

[0008] The guide groove is constructed in which multiple guide grooves are evenly distributed inside the grinding cylinder. The grinding cylinder has a horizontally arranged collection part that communicates with the guide grooves. The guide grooves are arranged in a ring shape.

[0009] A reciprocating lead screw is connected inside the grinding cylinder and coaxially arranged with the grinding cylinder. A threaded sleeve is connected to the surface of the reciprocating lead screw, and a pusher block is connected to the surface of the threaded sleeve through a connecting rod.

[0010] A barrier plate, which is distributed in a ring on the surface of the grinding cylinder, has a thickness greater than that of the grinding cylinder, and a support assembly is constructed at the lower part of the grinding cylinder.

[0011] Preferably, the pusher block is located inside and fits against the collection part, and the width of the pusher block is greater than the width of the guide groove.

[0012] Preferably, the surface of the grinding cylinder is constructed with a cap located on the back of the collecting portion, and the cross-sectional area of ​​the cap is smaller than the cross-sectional area of ​​the collecting portion.

[0013] Preferably, one end of the reciprocating lead screw extends through the outside of the grinding cylinder, and the end extending through the outside of the grinding cylinder is connected to a rotating handle.

[0014] Preferably, the support assembly includes a base plate disposed below the grinding cylinder, and bearing seats are connected to both sides of the base plate via support seats. The grinding cylinder is connected between the bearing seats, and a reinforcing assembly located directly below the grinding cylinder is connected to the inner side of the base plate.

[0015] Preferably, the reinforcing component includes a reinforcing plate fixed to the inner side of the base plate, and grooves are provided on the opposite inner sides of the reinforcing plate.

[0020] Compared with the prior art, the present invention provides a ball mill for manufacturing quartz sand powder, which has the following features:

[0021] Beneficial effects:

[0022] 1. This invention, through the combination of a guide groove and a collection part, utilizes an annular guide groove inside the ball mill. This allows the grinding media within the mill to move along the guide groove as the mill rotates, enabling better accumulation and transfer of energy. The shape and structure of the guide groove promote greater kinetic energy in the falling media, resulting in a stronger impact and grinding effect on the material, further enhancing the grinding effect. This increases the contact frequency between the media and the material, and the irregular movement facilitates thorough mixing of the media and the material, improving grinding uniformity and grinding efficiency.

[0023] 2. This invention utilizes the interaction of a magnet, a barrier plate, and a medium. The medium is magnetically connected to the magnet. On one hand, the magnet attracts the medium, causing it to move closer to the inner wall of the grinding cylinder. As the medium moves toward the magnet, it grinds the material. On the other hand, it attracts the falling medium, increasing its acceleration and thus generating a greater impact force on the quartz sand, improving the pulverization effect. Simultaneously, the medium near the magnet and the falling medium collide, enhancing the grinding effect of the medium on the material. Attached Figure Description

Detailed Implementation

[0032] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] In the existing ball mill, the force generated when the material collides with the media 15 during operation is relatively limited, that is, the impact force of the media 15 on the material is relatively fixed, and it is not able to grind the material well.

[0035] like Figures 1 to 7 As shown, a ball mill for manufacturing quartz sand powder includes: a grinding cylinder 1, which is cylindrical and has a grinding space inside; a guide groove 8, which has multiple grooves evenly distributed inside the grinding cylinder 1; a collection part 9, which is horizontally arranged inside the grinding cylinder 1 and communicates with the guide groove 8, and is annularly arranged; a reciprocating screw 7, which is connected to the inside of the grinding cylinder 1 and is coaxially arranged with the grinding cylinder 1; a threaded sleeve 14 is connected to the surface of the reciprocating screw 7; a pusher block 17 is connected to the surface of the threaded sleeve 14 through a connecting rod 16; the pusher block 17 is located inside the collection part 9 and fits against the collection part 9; and the width of the pusher block 17 is greater than the width of the guide groove 8; one end of the reciprocating screw 7 extends outside the grinding cylinder 1, and the end extending outside the grinding cylinder 1 is connected to a handle 18; the grinding cylinder 1... The other end is connected to a feeding mechanism 4, which provides quartz sand raw material to the ball mill. The feeding mechanism 4 is coaxially arranged with the grinding cylinder 1, and the material transmission direction is consistent with the axial direction of the grinding cylinder 1. This design can reduce the energy consumption of the material during the transmission process, because the material can directly enter the interior of the grinding cylinder 1 without changing direction, thereby improving the transmission efficiency. The surface of the grinding cylinder 1 is connected to a transmission part 2, and the surface of the bottom plate 3 is connected to a drive mechanism connected to the transmission part 2. Under the action of the drive mechanism, it can provide power for the operation of the equipment, so that the power generated after the drive mechanism works can be transmitted to the position of the grinding cylinder 1 through the transmission part 2 to drive the grinding cylinder 1 to rotate, thereby crushing and grinding the quartz sand raw material through the internal medium 15, improving the continuity of the action and the transmission effect.

[0036] The ball mill for manufacturing quartz sand powder, with the above-described structure, ensures stable operation. The grinding space provides sufficient room for the material and grinding media 15, guaranteeing grinding efficiency. Quartz sand is added to the ball mill via the feeding mechanism 4, and then the drive mechanism is activated. The power generated by the drive mechanism is transmitted through the transmission unit 2 to the grinding cylinder 1, causing it to rotate. As the grinding cylinder 1 rotates, the grinding media 15 moves along the guide groove 8. When the media 15 moves within the guide groove 8, it better accumulates and transfers energy. The shape and structure of the guide groove 8 allow the media 15 to gain greater kinetic energy upon falling, thereby producing… The stronger impact and grinding action further enhances the grinding effect, thereby increasing the contact frequency between the media 15 and the material. The irregular movement is conducive to the full mixing of the media 15 and the material, improving the uniformity of grinding and increasing the grinding efficiency of the material. Thus, the quartz sand raw material is crushed and ground by the internal media 15. The guide groove 8 and the collection part 9 help the material to be evenly distributed during the grinding process, avoiding excessive accumulation or loss of material in a certain area. The setting of the collection part 9 makes it easy to collect and discharge the ground material, improving the operating efficiency of the ball mill. The ring-shaped design of the guide groove 8 further enhances the uniform distribution effect of the material, and also helps the media 15 to be evenly distributed and move.

[0037] The rotational motion of the reciprocating screw 7 drives the threaded sleeve 14 and its surface connecting rod 16 and pusher block 17 to reciprocate. The pusher block 17 helps to clean residual materials and media 15 in the grinding space, preventing excessive accumulation and blockage of materials and media 15, and ensuring the continuous and stable operation of the ball mill. The pusher block 17 can fit against the collecting part 9, so that the collecting part 9 can provide certain guidance and restriction for the pusher block 17. Because the threaded sleeve 14 can move on its surface under the action of the reciprocating screw 7, and the pusher block 17 is located in the collecting part 9, it can restrict the movement of the threaded sleeve 14 and prevent the threaded sleeve from moving. The sleeve 14 rotates together with the reciprocating screw 7 instead of moving in a straight line, which improves the stability of the pusher block 17's movement. Furthermore, the pusher block 17 can avoid moving into the guide groove 8 during horizontal movement, thus avoiding deviation and interference. The design of the handle 18 allows the operator to intuitively see and control the rotation of the reciprocating screw 7. By rotating the handle 18, the operator can easily adjust the speed and direction of rotation of the reciprocating screw 7, thereby achieving precise control of the grinding process. This allows the reciprocating screw 7 to operate independently or move together with the ball mill, facilitating the diverse movement of the pusher block 17 and improving flexibility.

[0038] like Figures 1 to 5As shown, the surface of the grinding cylinder 1 has a cover 5 located on the back of the collecting part 9, and the cross-sectional area of ​​the cover 5 is smaller than that of the collecting part 9. With this design, the cover 5 is used to close the opening of the grinding cylinder 1 to prevent material from splashing during the grinding process, while the collecting part 9 is used to collect and discharge the ground quartz sand powder, which is usually located at the outlet of the grinding cylinder 1. The design of the cover 5 makes it easy to remove from the grinding cylinder 1, thereby allowing the operator to easily access the collecting part 9 and its internal components. The tight fit between the cover 5 and the collecting part 9 helps to prevent material and media 15 from leaking to the outside of the grinding cylinder 1 during the grinding process, thereby facilitating the discharge of material in the collecting part 9 from the location of the cover 5.

[0039] like Figures 1 to 7 As shown, the support assembly includes a base plate 3 located below the grinding cylinder 1. Both sides of the base plate 3 are connected to bearing seats 20 via support seats 6. The grinding cylinder 1 is connected between the bearing seats 20. The cross-sectional area of ​​the base plate 3 is larger than that of the grinding cylinder 1. A reinforcing assembly located directly below the grinding cylinder 1 is connected to the inner side of the base plate 3. The base plate 3 provides a wider support surface. This design enhances the stability of the entire device, making the grinding cylinder 1 run more smoothly and reducing displacement caused by vibration or impact. Since the grinding cylinder 1 is connected between the bearing seats 20, it can be driven to operate independently by an external drive component. The support assembly provides support for the grinding cylinder 1, and the reasonable layout improves the stability of the device operation. The reinforcing assembly can increase the movement of the medium 15 inside the grinding cylinder 1.

[0040] By combining the guide groove 8 and the collection part 9, the annular guide groove 8 inside the ball mill allows the grinding media 15 inside the grinding cylinder 1 to move along the guide groove 8 when it rotates, thus better accumulating and transferring energy. The shape and structure of the guide groove 8 can enable the media 15 to gain greater kinetic energy when falling, thereby generating a stronger impact and grinding effect on the material, further improving the grinding effect, increasing the contact frequency between the media 15 and the material, and the irregular movement is conducive to the full mixing of the media 15 and the material, improving the uniformity of grinding and increasing the grinding efficiency of the material.

[0041] Example 2

[0042] Based on the above embodiments, during the process of treating quartz stone, it cannot be guaranteed that the material in each part can fully contact the medium 15. Under the condition of large centrifugal force, the impact angle and force of the medium 15 on the liner will increase, resulting in faster wear of the liner.

[0043] like Figures 1 to 7As shown, the baffle plate 13 is arranged in a ring on the surface of the grinding cylinder 1. The thickness of the baffle plate 13 is greater than the thickness of the grinding cylinder 1. The baffle plate 13 helps to enhance the structural strength of the grinding cylinder 1, ensuring the safety and stability of the ball mill. The lower part of the grinding cylinder 1 has a support assembly. The reinforcing assembly includes a reinforcing plate 19 fixed to the inner side of the base plate 3. The reinforcing plate 19 is fixed to the inner side of the base plate 3, which can effectively increase the rigidity and strength of the base plate 3. This design allows the base plate 3 to better bear the weight of the grinding cylinder 1 and the components above it, thereby enhancing the structural stability of the entire equipment. The inner sides of the reinforcing plates 19 are provided with grooves 12. The grooves 12 are connected to the brackets 10. The design of the grooves 12 allows the brackets 10 to be flexibly connected between the reinforcing plates 19 while maintaining a certain degree of stability and firmness. The grooves 12 are coaxially arranged with the grinding cylinder 1. The upper part of the brackets 10 is connected to an arc-shaped structure. The magnet 11 has a cross-sectional area that matches that of the barrier plate 13. The arc-shaped magnet 11 can generate a certain magnetic force. The grinding cylinder 1 contains multiple irregularly distributed media 15, all of which are magnetically connected to the magnet 11, which helps to adsorb and fix some magnetic materials. When the barrier plate 13 overlaps with the magnet 11, the thickness of the barrier plate 13 can effectively isolate the magnetic force of the magnet 11 and prevent the magnet 11 from adsorbing with the media 15. At this time, the media 15 rotates normally in the grinding cylinder 1. When the barrier plate 13 does not overlap with the magnet 11, the magnet 11 and the media 15 are adsorbed. At this time, the media 15 is affected by the magnet 11 and moves closer to the magnet 11. The support assembly provides stable support for the ball mill, ensuring the stability and safety of the ball mill during operation. Through reasonable grinding space design and the movement mode of the media 15, efficient grinding of quartz sand is ensured.

[0044] During normal operation, the grinding media 15 is carried to a certain height by the rotation of the grinding cylinder 1 and then falls, impacting and grinding the material. When the baffle plate 13 moves to a position where it does not overlap with the magnet 11, the grinding media 15 forms a magnetic connection with the magnet 11. On one hand, the magnet 11 can exert a certain magnetic attraction on the grinding media 15, causing the grinding media 15 to move closer to the inner wall of the grinding cylinder 1 under the attraction of the magnet 11. During the movement of the grinding media 15 towards the magnet 11, it grinds the material. On the other hand, it attracts the falling grinding media 15, increasing the acceleration of the grinding media 15 so that the grinding media 15 can generate a greater impact force on the quartz sand, improving the crushing effect of the quartz sand. At the same time, the grinding media 15 close to the magnet 11 and the falling grinding media 15 collide, increasing the grinding effect of the grinding media 15 on the material, reducing the impact angle and force of the grinding media 15 on the grinding cylinder 1 liner, reducing the wear rate of the grinding cylinder 1 liner. When the grinding media 15 falls from a higher position, it has more horizontal displacement space, making the grinding... More quartz sand inside the cylinder 1 is impacted by the medium 15, rather than being limited to the area near the point where the medium 15 lands. Therefore, the quartz sand at different locations inside the cylinder can be crushed, making the crushing process more uniform and reducing the situation where local quartz sand is not fully crushed. This uniform distribution helps to reduce blind or weak areas in the magnetic field and improve the efficiency of the magnetic field. When the baffle plate 13 moves to coincide with the magnet 11, the magnet 11 breaks the force between itself and the grinding cylinder 1 and the medium 15, and thus slides back to its initial position under its own weight and the gravity of the medium 15. The support 10 and the magnet 11 on it are aligned with the center line of the grinding cylinder 1, which improves the stability of the movement of the magnet 11 and ensures that the magnetic attraction force generated by the magnet 11 can be effectively blocked by the baffle plate 13. The baffle plate 13 is connected to the surface of the grinding cylinder 1 in a ring, so that the magnet 11 intermittently adsorbs the medium 15. The intermittent operation of the magnet 11 can ensure that the material in each part can fully contact the medium 15.

[0045] The magnet 11, the baffle plate 13, and the medium 15 work together, and the medium 15 is magnetically connected to the magnet 11. On the one hand, the magnet 11 can exert a certain magnetic attraction on the medium 15, causing the medium 15 to move closer to the inner wall of the grinding cylinder 1 under the attraction of the magnet 11. During the movement of the medium 15 toward the magnet 11, the material is ground. On the other hand, the falling medium 15 is attracted, increasing the acceleration of the medium 15, so that the medium 15 can generate a greater impact force on the quartz sand, thereby improving the crushing effect of the quartz sand. At the same time, the medium 15 close to the magnet 11 and the falling medium 15 collide, increasing the grinding effect of the medium 15 on the material.
