Technical Field

[0001] This invention relates to a ball feeding metering device, specifically a ball feeding metering device for a ball mill, belonging to the field of ball mill ball feeding technology. Background Technology

[0002] Ball mills are widely used crushing equipment in the mining, cement, and chemical industries. They grind materials to the required fineness through the impact and friction of steel balls inside the rotating cylinder. To achieve efficient operation, an automatic ball metering system is crucial. It can accurately control the amount of steel balls added, avoid problems of over- or under-addition caused by human error, ensure stable grinding process, prevent material blockage or equipment overload, improve grinding efficiency, reduce steel ball and labor costs, and extend equipment service life.

[0003] A search revealed a Chinese patent with publication number CN211838232U that discloses an automatic ball feeding and metering device for a ball mill, comprising a ball hopper, a ball feeding device, a rotating ball separating device, a fixed ball separating device, a power device, a ball separating power device, and a control device; the ball hopper has an internal cavity along its long axis, a ball feeding port is provided at the higher end of the ball hopper, and a ball discharge port is provided at the bottom of the lower end of the ball hopper; one end of the transport channel is fixedly connected to the ball discharge port, and the other end is located above the rotating ball separating device.

[0004] While the above-mentioned solution can automatically add balls, its fixed-diameter conveying channel not only limits its adaptability to steel balls of different sizes, but also easily causes multiple steel balls to enter the conveying channel at the same time when conveying small-sized steel balls, leading to jamming and metering errors, resulting in low stability. To address these issues, we provide a ball mill ball metering device. Summary of the Invention

[0005] The purpose of this invention is to provide a ball mill ball metering device to solve the above-mentioned problems, thereby addressing the issues of easy jamming and metering errors, as well as low adaptability and stability in the prior art when transporting small-sized steel balls.

[0012] Preferably, a limiting slide bar two is fixedly connected to the outer surface of the conveying shell, and a limiting ring groove adapted to the limiting slide bar two is opened on the bottom surface of the adjusting drum.

Detailed Implementation

[0022] This invention provides a ball mill ball metering device.

[0023] Please see Figure 1 It includes a support mounting frame 1, on the outer surface of which an electrical control box is integrated. The electrical control box is electrically connected to the municipal power supply via wires, thereby effectively ensuring the normal power supply to the electrical equipment in this application.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 6 and Figure 8 The bearing mounting frame 1 is equipped with a conveying mechanism 2, which includes a ball box 201, a conical box 202 and a connecting ring 203. The bottom surface of the ball box 201 and the conical box 202 are fixedly connected, and the bottom surface of the conical box 202 is fixedly connected to the connecting ring 203. A feeding hopper is fixedly connected to one side of the top surface of the ball box 201. The feeding hopper and two guide plates 206 are combined to make the grinding balls move regularly in the ball box 201. The conical box 202 can significantly reduce the risk of clogging and ball jamming.

[0025] The outer surface of the connecting ring 203 is rotatably connected to the adjusting drum 204, and the bottom surface of the adjusting drum 204 is rotatably connected to the conveying housing 205. The outer surface of the conveying housing 205 is fixedly connected to the bearing mounting frame 1. The conveying housing 205 is fixed by four metal rods made of high-strength material, which effectively makes the conveying housing 205 more stable. The connecting ring 203 and the adjusting drum 204 are connected by a highly flexible rotating mechanism, and a sealing ring is installed between them. The sealing ring can prevent external dust and impurities from entering and affecting the rotation of the adjusting drum 204.

[0026] The top surface of the connecting ring 203 is provided with scale lines. By setting the scale lines, the rotation angle of the adjusting drum 204 can be directly observed when the adjusting drum 204 is driven to rotate, which makes it convenient for the staff to adjust the size of the opening of the connecting ring 203.

[0027] A ball guide plate 206 is fixedly connected to the inner wall of the ball hopper 201, and a metering component 207 is fixedly connected to the bottom surface of the conveying shell 205. With the setting of the two ball guide plates 206, the grinding balls in the ball hopper 201 can be effectively and stably guided into the conical hopper 202 in a loose and tracked manner.

[0028] The metering component 207 is the core unit for achieving precise and automatic control. Its structure mainly consists of a robust shell, a high-strength inductive sensor as the core detection element, a PLC controller for logic processing, a counter for cumulative statistics, and a signal transceiver module for communication hub. The high-strength inductive sensor is precisely positioned on a specific location inside the wear-resistant and impact-resistant shell. Its core function is to generate and maintain a stable high-frequency oscillating magnetic field. When the grinding ball passes through the detection area where the sensor is located along the set path, it will precisely change the magnetic field distribution characteristics of the area. The internal circuit of the sensor will quickly respond to the electromagnetic change caused by this metal object and convert it into a clear and stable electrical pulse signal output. Each ball that successfully passes through will trigger such a pulse event, ensuring the basis for accurate perception and counting of the passing of the grinding ball.

[0029] These pulse signals, captured and generated in real time by inductive sensors, are instantly transmitted to a counter for reception and processing. The counter, acting as an accumulation mechanism, is tasked with continuously accumulating and counting the received valid pulse signals, dynamically displaying or storing the accumulated value. The key to the control logic lies in the pre-set target value. When the current accumulated value of the counter precisely reaches or exceeds this preset value, it signifies the completion of the measurement task. At this point, the signal transceiver module, acting as an information transmission bridge, is immediately activated. It sends a specific instruction signal containing "measurement completed" or "target achieved" information to the PLC controller with minimal delay. Upon receiving this signal, the PLC controller, based on its embedded pre-defined program logic, outputs a control command without delay, disconnecting the drive control loop and forcibly shutting down the drive motor 210, thereby stopping the conveying of grinding balls. This complete process, from detection, counting, judgment to power-off execution, forms an efficient, responsive, and wear- and vibration-resistant automated measurement closed-loop control system. All components involved in the measurement components are based on mature and reliable existing technologies; their specific technical details will not be elaborated upon here.

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8An active shaft 208 is rotatably connected to the inner wall of the conveying housing 205. A guide ball disk 209 is fixedly connected to the outer surface of the active shaft 208. A drive motor 210 is fixedly connected to the outer surface of the conveying housing 205 through a fixed frame. The output end of the drive motor 210 is fixedly connected to the active shaft 208. The drive motor 210 is started by the PLC controller in the metering component 207. The start of the drive motor 210 can effectively drive the guide ball disk 209 on the surface of the active shaft 208 to rotate inside the conveying housing 205. Through the rotation of the guide ball disk 209, the grinding balls in the conical hopper 202 can be conveyed to the metering component 207 in an equal and uniform manner. The equal and uniform conveying can significantly improve the accuracy of the metering component 207 in measuring the grinding balls.

[0031] The drive motor 210 falls within the scope of common knowledge in the art and is a conventional electrical device that is widely used in the prior art and is extensively described in technical manuals and standard texts. Given its versatility and the full understanding of its structure, working principle and selection by those skilled in the art, this application will not elaborate on or limit the specific model or internal structural details of the motor itself, thereby emphasizing that it is not the innovation of this application. It should be made clear that the drive motor 210 can also be replaced by other types of power sources with equivalent functions that are known to those skilled in the art.

[0032] The bottom surface of the connecting ring 203 is provided with a limiting groove 211. The inner wall of the limiting groove 211 is slidably connected to a limiting slider 212. The bottom surface of the limiting slider 212 is fixedly connected to an adjusting plate 213. The bottom surface of the adjusting plate 213 is fixedly connected to a limiting rod 214. The inner bottom wall of the adjusting cylinder 204 is provided with a limiting groove 215 that matches the limiting rod 214. When the adjusting cylinder 204 is driven to rotate, the opening on the connecting ring 203 can be effectively opened to the required size through the coordinated action of the limiting groove 211 and the limiting slider 212, and the limiting rod 214 and the limiting groove 215.

[0033] The outer surface of the conveying housing 205 is fixedly connected to a limiting slide rod 216. The bottom surface of the adjusting drum 204 is provided with a limiting ring groove 224 that matches the limiting slide rod 216. Through the coordinated cooperation of the limiting slide rod 216 and the limiting ring groove 224, the adjusting drum 204 can support the conveying housing 205 whether it is stationary or rotating, making the guide ball disk 209 inside the conveying housing 205 more stable during rotation.

[0034] A mounting box 217 is fixedly connected to the top surface of the connecting ring 203. A sliding baffle 218 is slidably connected to the inner wall of the mounting box 217. A connecting slide rod 219 is fixedly connected to the top surface of the sliding baffle 218. The outer surface of the connecting slide rod 219 is slidably connected to the mounting box 217. The sliding baffle 218 and the connecting slide rod 219 are slidably connected to the mounting box 217, which can effectively limit the sliding baffle 218 and the connecting slide rod 219, so that the sliding baffle 218 and the connecting slide rod 219 can only slide vertically in the mounting box 217 and cannot rotate.

[0035] A support spring 220 is sleeved on the outer surface of the connecting slide rod 219. The two ends of the support spring 220 are fixedly connected to the mounting box 217 and the sliding baffle 218, respectively. By setting the sliding baffle 218, pressure can be applied to the support spring 220 during the process of pulling the connecting slide rod 219 out of the mounting box 217, causing it to contract and deform. The rebound characteristics of the support spring 220 effectively support the sliding baffle 218, so that the fixed rod 222 can be more stably limited in the limiting groove of the fixed groove plate 223. The support spring 220 is made of high-strength and high-toughness material, making it more durable.

[0036] A connecting rod 221 is fixedly connected to the end of the connecting slide rod 219 away from the sliding baffle 218. A fixing rod 222 is fixedly connected to the end of the connecting rod 221 away from the connecting slide rod 219. A fixing groove plate 223 is fixedly connected to the outer surface of the adjusting cylinder 204. A limiting groove adapted to the fixing rod 222 is opened on the outer surface of the fixing groove plate 223. By embedding the fixing rod 222 into the limiting groove in the fixing groove plate 223, the adjusting cylinder 204 can be effectively limited so that it cannot rotate again. A handle is fixedly installed on the outer surface of the fixing groove plate 223. The handle makes it easier to drive the adjusting cylinder 204 in the inner wall of the fixing groove plate 223 to rotate.

[0037] Please refer to it again. Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The bearing mounting frame 1 is equipped with a vibration mechanism 3 on its exterior. The vibration mechanism 3 includes a mounting plate 301. The outer surface of the mounting plate 301 is fixedly connected to the bearing mounting frame 1. The mounting plate 301 effectively supports and limits the components in the vibration mechanism 3, enabling each component in the vibration mechanism 3 to operate stably. The mounting plate 301 and the bearing mounting frame 1 are fixed together by double bolts. This fixing method facilitates the disassembly, assembly, and maintenance of the vibration mechanism 3 by the staff in the later stages.

[0038] The inner wall of the mounting plate 301 is rotatably connected to a driven connecting shaft 302, and a driven turntable 303 is fixedly connected to the outer surface of the driven connecting shaft 302. The outer surface of the driven turntable 303 is provided with a shaped groove 304. During use, a protective shell is installed on the outer surface of the driven turntable 303. For the sake of intuitive viewing and understanding in the attached drawings, the protective shell is not shown in the drawings. The protective shell can protect the driven turntable 303 and effectively prevent external dust and impurities from entering the shaped groove 304. The driven connecting shaft 302 not only limits the movement of the driven turntable 303, but also enables the driven turntable 303 to rotate synchronously when the driven connecting shaft 302 is driven to rotate.

[0039] The inner wall of the irregular chute 304 is slidably connected to a driven slide column 305. A connecting slide block 306 is fixedly connected to the outer surface of the driven slide column 305. A reciprocating slide rod 307 is fixedly connected to the outer surface of the connecting slide block 306. A vibrating plate 308 is fixedly connected to the outer surface of the reciprocating slide rod 307. The outer surfaces of the connecting slide block 306 and the reciprocating slide rod 307 are slidably connected to the mounting plate 301. By driving the driven turntable 303 to rotate, combined with the synergistic effect of the irregular chute 304 and the driven slide column 305, and the connecting slide block 306 and the reciprocating slide rod 307, the two vibrating plates 308 can effectively drive the two sides of the conical material box 202 to vibrate. Through vibration, the grinding balls fall evenly and continuously in the conical material box 202, avoiding blockage or jamming, promoting the rapid and smooth movement of the grinding balls, effectively improving the ball feeding efficiency and speed, improving the accuracy and controllability of the ball feeding amount, reducing the number of manual unblocking operations, reducing operational risks and improving overall operating efficiency.

[0040] One end of the driven connecting shaft 302 is fixedly connected to a driven small sprocket 309. The outer surface of the driven small sprocket 309 is fixedly connected to the driven turntable 303. A transmission chain 310 is drivenly connected to the outer surface of the driven small sprocket 309. A driven large sprocket 311 is drivenly connected to the outer surface of the transmission chain 310. The outer surface of the driven large sprocket 311 is fixedly connected to the drive shaft 208. By driving the drive shaft 208 to rotate, the transmission chain 310 on the surface of the driven large sprocket 311 can be effectively driven to rotate. The diameter of the driven large sprocket 311 is larger than the diameter of the driven small sprocket 309. Even when the driven large sprocket 311 rotates slowly, it can still drive the driven small sprocket 309 to rotate at high speed through the transmission chain 310, effectively avoiding the reduction of the vibration effect of the vibrating plate 308 due to the slow rotation of the driven large sprocket 311.

[0041] The structural representations of the components shown in the accompanying drawings are intended to provide conceptual references. Their forms and interrelationships provide a basic framework for understanding the overall design intent. It is important to emphasize that these illustrations are not rigid templates for the final product. In the process of transforming the design into an actual product or its subsystem, in-depth and meticulous adaptive adjustments and optimizations must be made based on the specific constraints of the project. This mainly includes fully considering the core functional requirements of the specific application scenario, rigorously assessing the physical limitations of the actual assembly, and strictly referring to the current material properties, manufacturing process levels, and cost control requirements. Therefore, it is necessary to systematically review and revise the geometric parameters, key dimensions, and material specifications of the components to ensure that the parameters achieve an optimal balance between theoretical feasibility and engineering practicality.

[0042] Working principle: First, grinding balls are placed into the ball hopper 201. The inclined arrangement of the two guide plates 206 allows the grinding balls to be loosely and systematically buffered into the conical hopper 202. Then, according to the specifications of the grinding balls, the connecting rod 221 is moved upwards, causing the fixing rod 222 to disengage from the fixing groove plate 223, releasing the constraint of the adjusting drum 204. At this time, pulling the pull rod on the surface of the fixing groove plate 223 drives the adjusting drum 204 to rotate on the surface of the connecting ring 203. During the rotation of the adjusting drum 204, the combined action of the limiting slide groove 1 211 and the limiting slider 212, and the limiting slide rod 1 214 and the limiting slide groove 215, enables the six adjusting... The synchronous movement of plate 213 opens the opening of connecting ring 203. After the opening of connecting ring 203 is opened to the required size, connecting rod 221 is released. Fixed rod 222 will be stably reset into fixed groove plate 223 by the rebound force of support spring 220, which will again limit the adjusting drum 204. At this time, the drive motor 210 can be started by the PLC controller in metering component 207. The drive motor 210 drives the drive shaft 208 to rotate. The rotation of drive shaft 208 drives the guide ball disk 209 to rotate. The rotation of guide ball disk 209 can transport the grinding balls in the conical material box 202 to the metering component 207 in an equal and uniform manner, effectively being metered by the metering component 207. The high-intensity inductive sensor in component 7 performs measurement. When the measurement reaches the preset value, the PLC controller in the measurement component 207 will immediately shut down the drive motor 210 to stop adding balls. This design allows the entire device to adapt to grinding balls of different sizes, effectively avoiding ball jamming and significantly improving the accuracy of the measurement process in the measurement component 207. Secondly, during the rotation of the drive shaft 208, it will synchronously drive the driven large sprocket 311 to rotate. The rotation of the driven large sprocket 311 drives the transmission chain 310, which in turn drives the driven small sprocket 309 to rotate. The rotation of the driven small sprocket 309 drives the driven connecting shaft 302 to rotate. The driven connecting shaft 302 rotates, driving the driven turntable 303 to rotate. During the rotation of the driven turntable 303, the combined action of the irregular groove 304, the driven sliding column 305, the connecting slider 306, and the reciprocating slide rod 307 effectively drives the two vibrating plates 308 to apply vibration to the conical material box 202. Through vibration, the grinding balls fall evenly and continuously in the conical material box 202, avoiding blockage or jamming, promoting the rapid and smooth movement of the grinding balls, effectively improving the ball feeding efficiency and speed, improving the precision and controllability of the ball feeding amount, reducing the number of times manual unblocking is required, reducing operational risks and improving overall operating efficiency, further making the device more practical.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
