Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a ball mill that facilitates batch feeding. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. The processing and preparation of refined white glass bottles requires the raw materials to be put into the ball mill for batch grinding. Cobalt oxide and nickel oxide are added to the raw materials as decolorizing agents to remove the color, and sodium sulfate and sodium nitrate are added as clarifying agents to make the glass bottles clearer and improve their transparency.

[0003] In existing technologies, traditional ball mills typically employ a one-time feeding method, where all materials to be ground are added into the mill cylinder at once before operation begins. However, this feeding method has several drawbacks: Firstly, adding a large amount of material at once leads to uneven distribution of the material within the cylinder, with material accumulation in some areas and insufficient contact between the grinding media and the material in others, thus affecting grinding efficiency and quality. Secondly, for materials with strict requirements on grinding particle size, one-time feeding makes it difficult to achieve precise control of the grinding process and flexibly adjust the feeding amount according to the grinding needs at different stages, resulting in a wide range of product particle size distribution, which is insufficient to meet the production requirements of high-quality products.

[0004] To address the problems existing in the above-mentioned technologies, a ball mill that facilitates batch feeding is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a ball mill that facilitates batch feeding, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ball mill that facilitates batch feeding, comprising a base, a ball mill cylinder, a support device and a drive device, wherein the ball mill cylinder is provided with a feed inlet and a discharge outlet at both ends, a feeding cylinder is fixedly installed at the feed inlet of the ball mill cylinder, a conveying spiral blade is fixedly installed on the inner wall of the feeding cylinder, and a batch feeding device is rotatably connected to the end of the feeding cylinder;

[0007] The batch feeding device includes a feeding cylinder, a second support roller, and a self-locking motor.

[0008] Install the ball mill cylinder horizontally on the first support roller of the support device, ensuring that the ball mill cylinder can rotate freely. Install the drive unit, connect the motor, reducer, and coupling, and adjust them to normal operating conditions. Open the end cover and load the raw materials to be added into the distribution chamber according to their type. Replace the end cover. The operator inputs parameters such as the feeding amount, feeding time interval, and feeding sequence of each batch of materials on the control panel according to the production process requirements. Start the ball mill, and the drive unit will drive the ball mill cylinder to start rotating. At the same time, the controller controls the self-locking motor to drive the distribution cylinder according to preset parameters. The mill rotates to bring the first receiving chamber to its highest point and opens the corresponding control valve to begin adding the first batch of material into the mill cylinder. After the first batch of material is added, the controller closes the control valve, and the distribution cylinder continues to rotate to bring the next receiving trough to its highest point. The corresponding control valve is then opened to add the second batch of material. This process is repeated to complete the batch feeding of each batch of material. As the material rotates within the mill cylinder, it collides and rubs against the grinding media, gradually being ground into the desired particle size. After grinding, the product is discharged from the outlet of the mill cylinder and enters the subsequent processing steps.

The output end of the motor is connected to the input end of the reducer through the coupling, and the output end of the reducer is connected to the first support roller to provide power for the rotation of the ball mill cylinder.

[0012] As a preferred embodiment of this utility model, the dispensing cylinder is placed on the second support roller, and the rotation of the dispensing cylinder is supported by the rolling of the second support roller. A transmission belt is configured to connect the dispensing cylinder and the self-locking motor.

[0013] The self-locking motor drives the transmission belt to rotate the dispensing cylinder, so that the raw materials inside the dispensing cylinder can be fed and used in sequence.

[0014] As a preferred embodiment of the present invention, the material distribution cylinder has a plurality of material distribution chambers inside, the outer wall of the material distribution chambers is provided with a feeding port and an end cap is installed on the feeding port, the inner wall of each material distribution chamber is provided with an inclined guiding area, the bottom end of the inclined guiding area is provided with a discharge port and a control valve is installed on the discharge port.

[0015] The feed inlet allows various raw materials to be added into different material distribution chambers. The end cap seals the feed inlet, and the raw materials stored in the material distribution chamber are transported to the control valve along the inclined guide zone under gravity.

[0016] As a preferred technical solution of this utility model, the batch feeding device also includes an operation panel with a built-in controller. The controller is electrically connected to the self-locking motor and the control valve respectively. The operation panel is used to input the parameters of batch feeding.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By feeding materials in batches, the materials can be more evenly distributed inside the ball mill cylinder, avoiding material accumulation and increasing the effective contact area between the grinding media and the materials, thereby improving grinding efficiency and shortening grinding time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3A ball mill for easy batch feeding includes a base 2, a ball mill cylinder 1, a support device, and a drive device. The ball mill cylinder 1 has an inlet and an outlet at both ends. A feeding cylinder 16 is fixedly installed at the inlet of the ball mill cylinder 1. Conveying spiral blades 17 are fixedly installed on the inner wall of the feeding cylinder 16. A batch feeding device is rotatably connected to the end of the feeding cylinder 16. The batch feeding device includes a distributing cylinder 8, a second support roller 9, and a self-locking motor 11. The ball mill cylinder 1 is horizontally mounted on the first support roller 4 of the support device, ensuring that the ball mill cylinder 1 can move freely. Rotate; install the drive unit, connect the motor 6, reducer 5, and coupling 7, and adjust them to normal working condition. Open the end cover 15, load the raw materials to be added into the distribution chamber 12 according to their type, and reset the end cover 15. The operator inputs parameters such as the feeding amount, feeding time interval, and feeding sequence of each batch of materials on the operation panel 18 according to the production process requirements, starts the ball mill, and the drive unit drives the ball mill cylinder 1 to start rotating; at the same time, the controller controls the drive self-locking motor 11 to drive the distribution cylinder 8 to rotate according to the preset parameters. The first receiving chamber is rotated to its highest position, and the corresponding control valve 14 is opened to begin adding the first batch of material into the ball mill cylinder 1. After the first batch of material is added, the controller closes the control valve 14, and the distribution cylinder 8 continues to rotate, bringing the next receiving trough to its highest position. The corresponding control valve is then opened to add the second batch of material. This process is repeated to complete the batch feeding of each batch of material. As the material rotates within the ball mill cylinder 1, it collides and rubs with the grinding media, gradually being ground into the required particle size. After grinding, the product is discharged from the outlet of the ball mill cylinder 1 and enters the subsequent processing steps. By feeding in batches, the material can be more evenly distributed within the ball mill cylinder 1, avoiding material accumulation and increasing the effective contact area between the grinding media and the material, thereby improving grinding efficiency and shortening grinding time. The batch feeding method allows for flexible adjustment of the feeding amount according to the grinding requirements of different stages, enabling precise control of the grinding process, achieving a more uniform particle size distribution, improving product quality and stability, and meeting the production requirements of high-quality products.

The ball mill cylinder 1 is filled with grinding media for grinding materials.

[0028] Specifically, the support device includes two symmetrically arranged roller groups, each roller group consisting of two first rollers 4. The first rollers 4 are structurally matched with the transmission rail 3. The ball mill cylinder 1 is placed on the first rollers 4, and the ball mill cylinder 1 is rotated by the rolling of the first rollers 4. The roller groups are fixedly installed on the base 2.

[0029] Specifically, the drive unit includes a motor 6, a coupling 7, and a reducer 5. The output end of the motor 6 is connected to the input end of the reducer 5 through the coupling 7, and the output end of the reducer 5 is connected to the first support roller 4 to provide power for the rotation of the ball mill cylinder 1.

[0030] Specifically, the dispensing cylinder 8 is placed on the second support roller 9, and the dispensing cylinder 8 rotates by the rolling support of the second support roller 9. A transmission belt 10 is configured to connect the dispensing cylinder 8 and the self-locking motor 11. The self-locking motor 11 drives the transmission belt 10 to drive the dispensing cylinder 8 to rotate, so that the raw materials inside the dispensing cylinder 8 can be fed and used in sequence.

[0031] Specifically, the inside of the distributing cylinder 8 is formed with several distributing chambers 12. The outer wall of the distributing chamber 12 is provided with a feeding port, and an end cap 15 is installed on the feeding port. The inner wall of each distributing chamber 12 is formed with an inclined guiding area 13. The bottom end of the inclined guiding area 13 is provided with a discharge port, and a control valve 14 is installed on the discharge port. Through the feeding port, various raw materials can be added into the distributing chambers 12. At the same time, the end cap 15 can seal the feeding port.

The end cover 15 is opened, and the raw materials to be added are loaded into the feeding chamber 12 according to their type. The end cover 15 is then reset. The operator inputs parameters such as the feeding amount, feeding time interval, and feeding sequence for each batch of materials on the operation panel 18 according to the production process requirements. The ball mill is then started, and the drive unit drives the ball mill cylinder 1 to rotate. Simultaneously, the controller controls the drive self-locking motor according to preset parameters. Machine 11 drives the distribution cylinder 8 to rotate, so that the first receiving chamber is at its highest point, and opens the corresponding control valve 14 to start adding the first batch of material into the ball mill cylinder 1. After the first batch of material is added, the controller closes the control valve 14, and the distribution cylinder 8 continues to rotate, so that the next receiving trough is at its highest point, and opens the corresponding control valve to add the second batch of material.

After grinding, the product is discharged from the discharge port of the ball mill cylinder 1 and enters the subsequent processing steps.
