A feed pipe is installed in the middle of one side of the barrel via a bearing, and a discharge pipe is installed in the middle of the other side of the barrel via a bearing. A gear ring is fixedly installed on one side of the barrel's circumference. A first drive motor is fixedly installed at both ends of the support frame near the feed pipe, and a drive gear is installed at the output end of the first drive motor. The inner wall of the barrel's circumference is configured as a rough grinding plate. Multiple grinding rods at equal angles are fixedly connected between the inner walls of the two sides of the barrel. A mounting frame is fixedly installed on the inner wall of the other side of the barrel, and a transmission box is fixedly installed in the middle of the mounting frame. Multiple rotating rollers are rotatably arranged on the outer side of the transmission box, and the multiple grinding rods are located on the outer circumference of the multiple rotating rollers. A filter screen is fixedly arranged between the inner side of the mounting frame and the outlet end of the barrel, and the filter screen is detachably installed from the barrel.

[0007] Preferably, the lower ends of both ends of the gear ring are respectively engaged with the two drive gears.

[0008] Preferably, a branch pipe is fixedly connected between the top ends of the two bearing sleeves, and an air inlet pipe is fixedly connected around the circumference of the branch pipe, while an exhaust pipe is fixedly connected to both sides of the bottom end of the branch pipe.

[0009] Preferably, airflow holes are provided on both sides of the outer circumference of the barrel, and a solenoid valve is fixedly installed inside the airflow hole. A detachable screen is installed at the upper end of the airflow hole. A flow guide is fixedly connected to the output end of the exhaust pipe, and a flow suppressing sleeve is fixedly connected at an incline between the lower ends of the four inner walls of the flow guide. The inner diameter of the exhaust pipe is larger than the diameter of the airflow hole, the width of the flow guide is larger than the diameter of the airflow hole, and the bottom ends of the flow guide and the flow suppressing sleeve are sealed and fitted to the circumference of the barrel.

[0010] Preferably, the grinding rod has grinding grooves on its circumference.

[0011] Preferably, a second drive motor is fixedly installed inside the transmission box, and a sun gear is fixedly installed at the output end of the second drive motor. The sun gear is circumferentially meshed with multiple planetary gears, and the end of each planetary gear is located outside the transmission box. The end of the planetary gear is detachably inserted into the rotating roller.

[0012] Preferably, the plurality of rollers are provided with teeth and abrasive patterns on their circumference, and the teeth and abrasive patterns of the plurality of rollers are different.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention proposes a ball milling device for producing nanomaterials. A first drive motor starts the drive gear, which rotates the gear ring and the barrel, causing the ball milling parts to tumble inside the barrel. The inner circumference of the barrel is set with a rough grinding plate. Multiple grinding rods are arranged between the inner walls of both sides of the barrel. A mounting frame, transmission box, and rotating rollers are arranged on the inner wall of the other side of the barrel. The workpiece tumbles inside the barrel along with the rough grinding plate and the ball milling parts for primary grinding. Then, a second drive motor, driven by a sun gear and multiple planetary gears, causes multiple rotating rollers to rotate in opposite directions for secondary grinding. Multiple grinding rods are located on the outer circumference of the multiple rotating rollers, and their circumferences are decorated with grinding patterns. The rotating rollers have teeth on their circumferences, further enhancing the ball milling and shaping effect on the workpiece, ensuring good ball milling uniformity of the product, and improving production efficiency.

[0015] This invention proposes a ball milling device for producing nanomaterials. The device comprises an airflow hole, a flow guide, branch pipes, an inlet pipe, and an outlet pipe at the top of the mill barrel. A solenoid valve is fixedly installed inside the airflow hole. The outlet pipe has an inner diameter larger than the airflow hole diameter. When the airflow hole rotates with the mill barrel into the flow guide, the solenoid valve opens, and the outlet pipe exhausts gas into the flow guide, filling the flow guide with gas. This prevents nanomaterials from escaping from the airflow hole and also uses the airflow to impact and wash away dust adhering to the rough grinding plate, enhancing the friction between the ball mill and the workpiece. Furthermore, the width of the flow guide is greater than the diameter of the airflow hole, which helps prolong the airflow impact time, and the flow-damping sleeve helps reduce the diffusion and escape of the airflow.
