Description

Technical Field

[0001] This utility model relates to the technical field of mineral processing equipment, specifically to an anti-clogging ball-adding device for mineral processing. Background Technology

[0002] In the field of mineral processing, ball mills are the core equipment for crushing ores. Their grinding efficiency is closely related to the amount and accuracy of the grinding balls. Traditional ball feeding devices usually feed grinding balls into the ball mill manually or through simple mechanical structures. However, due to the complex environment of ore processing, problems such as channel blockage and grinding ball adhesion are prone to occur during the ball feeding process. In recent years, anti-blockage ball feeding devices have gradually adopted structures such as compartmentalized material guiding and vibration unblocking. However, existing technologies still have defects such as structural redundancy and insufficient dynamic response, making it difficult to adapt to the precise control requirements of efficient and continuous production.

[0003] Specifically, traditional ball-adding devices are difficult to adjust the ball-adding frequency and single-time addition amount according to the real-time operating conditions of the ball mill. This defect can easily cause an imbalance in the ball filling rate inside the ball mill, directly affecting the fineness of ore grinding and equipment energy consumption, and even causing equipment overload shutdown due to excessive ball addition.

[0004] In view of this, an anti-clogging ball-adding device for mineral processing is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing ball-adding devices are not convenient for adjusting the ball-adding frequency and the amount added at one time according to the real-time operating conditions of the ball mill, and to provide an anti-clogging ball-adding device for mineral processing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a ball mill body for mineral processing, comprising a ball mill body and a ball filling port opened on the top of the ball mill body, wherein a plurality of feeding components are provided on the top of the ball filling port, and the plurality of feeding components are fixedly connected to the ball mill body through a bracket;

[0007] The feeding component includes a base fixedly connected to the ball feeding port and a guide port opened on the base. A storage bin is provided above the base, and multiple grinding balls to be added are placed in the storage bin. A channel is opened at the bottom of the storage bin, and a feeding seat for conveying the grinding balls to the guide port is slidably arranged in the channel.

[0008] Preferably, the storage bin has a rectangular cross-section, and the side length of the inner wall of the storage bin is slightly larger than the diameter of the grinding balls, so that the multiple grinding balls are arranged vertically inside the storage bin.

[0009] Preferably, the height of the channel is greater than the diameter of the grinding ball and the height of the channel is less than the sum of the diameters of the two grinding balls.

[0010] Preferably, an electric push rod is fixedly connected to the storage bin, and a baffle plate is fixedly connected to the extended end of the electric push rod. The baffle plate is fixedly connected to the feeding seat through a connecting plate. The baffle plate is used to block the balls to be released in the storage bin after the feeding seat leaves the channel. The baffle plate is provided with a guide surface to facilitate lifting the grinding balls.

[0011] Preferably, the feeding seat has a storage groove for storing the grinding balls at the bottom of the storage bin, and sliders are fixedly connected to both sides of the feeding seat. The inner wall of the storage bin has a groove that matches the size of the slider.

[0012] Preferably, when the electric push rod retracts to its maximum distance, the feeding seat is located directly above the guide port.

[0016] 2. The anti-clogging ball feeding device for mineral processing provided by this utility model, through the sliding cooperation between the feeding seat and the chute and the guide surface design of the baffle plate, forces the separation of the sticky grinding balls under the drive of the electric push rod, avoiding channel blockage caused by the accumulation of grinding balls or the adhesion of slurry, ensuring the device can run continuously for a long time and reducing the frequency of downtime maintenance.

[0017] 3.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5 .

[0028] This utility model relates to an anti-clogging ball feeding device for mineral processing, comprising a ball mill body 1 and a ball feeding port 11 opened on the top of the ball mill body 1. Multiple feeding components 2 are provided on the top of the ball feeding port 11, and all feeding components 2 are fixedly connected to the ball mill body 1 via a bracket 12. Each feeding component 2 includes a base 21 fixedly connected to the ball feeding port 11 and a guide port 22 opened on the base 21. A storage bin 23 is provided above the base 21, containing multiple grinding balls to be added. A channel 24 is opened at the bottom of the storage bin 23, and a feeding seat 29 for conveying the grinding balls to the guide port 22 is slidably arranged within the channel 24. This arrangement disperses the impact pressure of the concentrated falling grinding balls on the ball feeding port 11, while the bracket 12 ensures a rigid connection between each component and the ball mill body 1, preventing structural displacement due to vibration. This improves ball feeding stability and prevents the risk of simultaneous blockage of multiple channels 24.

[0029] The storage bin 23 has a rectangular cross-section, and the side length of the inner wall of the storage bin 23 is slightly larger than the diameter of the grinding balls, so that multiple grinding balls are arranged vertically in the storage bin 23. This arrangement can constrain the grinding balls to be stacked vertically in a single row, eliminate the jamming problem caused by the rolling or tilting of the grinding balls, and provide an orderly arrangement basis for subsequent release of each ball.

[0030] Specifically, the height of channel 24 is greater than the diameter of the grinding ball and less than the sum of the diameters of the two grinding balls. By limiting the height of channel 24 to allow only a single grinding ball to pass through, the possibility of multiple balls falling side by side is blocked from the physical structure, ensuring that only one grinding ball is moved to the guide port 22 by the feed seat 29 each time, thus achieving precise control of the number of balls added.

[0031] Secondly, an electric push rod 25 is fixedly connected to the storage bin 23. A baffle plate 26 is fixedly connected to the extended end of the electric push rod 25. The baffle plate 26 is fixedly connected to the feeding seat 29 through a connecting plate 28. The baffle plate 26 is used to block the balls to be released in the storage bin 23 after the feeding seat 29 leaves the channel 24. The baffle plate 26 has a guide surface 27 that facilitates the lifting of the grinding balls. This setting allows the baffle plate 26 to block the subsequent grinding balls when the feeding seat 29 moves out to feed the balls, ensuring the orderly release of the grinding balls. At the same time, the inclination angle of the guide surface 27 guides the grinding balls to slide smoothly into the feeding seat 29, reducing the interference of frictional resistance on the release action and preventing the grinding balls from sticking together.

[0032] Furthermore, the feeding seat 29 is provided with a storage groove 210 for storing the grinding balls at the bottom of the storage bin 23. Slider 211 is fixedly connected to both sides of the feeding seat 29. A groove 212 that matches the size of the slider 211 is provided on the inner wall of the storage bin 23. This setting can ensure the stable positioning of the grinding balls during the conveying process. With the precise sliding guidance of the slider 211 and the groove 212, the moving trajectory of the feeding seat 29 is strictly aligned with the guide port 22, avoiding the grinding balls from falling or getting stuck due to deviation.

[0033] Furthermore, when the electric push rod 25 retracts to its maximum distance, the feed seat 29 is positioned directly above the guide port 22. This arrangement ensures that the feed seat 29 can precisely move the grinding balls to the guide port 22, guaranteeing the accuracy of the grinding ball delivery.

[0034] In addition, the height of the baffle plate 26 is the same as the diameter of the grinding balls. This setting ensures that the baffle plate 26 can lift the grinding balls in the storage bin 23 except for the storage slot 210 under the drive of the electric push rod 25, thus ensuring the stability of subsequent ball addition.

[0035] Working principle:

[0036] When the anti-clogging ball feeding device for mineral processing is working, the grinding balls in the storage bin 23 are arranged in a single vertical row under the action of gravity. The bottommost grinding ball falls into the receiving groove 210 of the feeding seat 29. When the electric push rod 25 starts to retract, the feeding seat 29 slides horizontally along the channel 24 through the guide of the slider 211 and the chute 212, synchronously conveying the grinding balls in the receiving groove 210 to the top of the guide port 22. At this time, the grinding balls fall accurately into the ball mill through the guide port 22 under the action of gravity. The baffle plate 26 lifts up and blocks the subsequent grinding balls in the storage bin 23. When the electric push rod 25 extends and resets, the feeding seat 29 retracts to the bottom. At the bottom of the storage bin 23, the baffle plate 26 releases its obstruction of the grinding balls, and the next grinding ball automatically falls into the receiving trough 210, forming a cyclical ball-adding action. Through the strict matching of the height of the channel 24 with the diameter of the grinding balls, the precise correspondence between the height of the baffle plate 26 and the size of the grinding balls, and the displacement linkage between the feeding seat 29 and the guide port 22, the coordinated control of single-ball separation, directional conveying, and anti-blocking interception is achieved, ensuring that the ball-adding process is continuous, stable, and without blockage. In specific implementation, the ball-adding frequency is controlled by controlling the speed of the retraction and extension of the electric push rod 25, and the number of balls added is controlled by controlling the number of times the electric push rod 25 retracts and extends.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
