At present, the existing grinding and crushing machines for magnesium powder production have the following problems.

In the existing equipment for crushing magnesium powder by using high-speed air flow, the air flow is unevenly distributed in the crushing cavity, which leads to different degrees of impact and friction during the crushing process, resulting in uneven crushing and large difference in particle size. In addition, in the production process of magnesium ingots, if the internal compositions are unevenly distributed and there are impurities, inclusions or different phase structures, these parts will show high hardness and toughness during crushing, and are difficult to be fully crushed, thus forming blocks with hard strength. The traditional grinding and crushing device for magnesium powder production does not have the capability of refining and crushing hard magnesium powder raw materials, so it cannot meet the existing demand for the raw material crushing equipment for magnesium powder production.

The controller 42 is electrically connected with the gas compressor 6, the noise sensor 31, the driving motor 32 and the driving electromagnet 41 respectively.

The model of the controller 42 is SYC89C52RC-401.

The model of the noise sensor 31 is BR-ZS1.

When in use, magnesium powder production raw materials are put into the crushing cavity 17, and the magnesium powder production raw materials are put into the crushing cavity 17. The controller 42 controls the start of the gas compressor 6; the gas compressor 6 conveys the generated compressed gas to the interior of the main gas pipe 9 through the compressed gas pipe 7. In the initial state, the shunt valve 12 is in the open setting and the main gas valve 13 is in the closed setting; the main gas pipe 9 conveys compressed gas to the interior of the shunt pipe 11 through the annular pipe 10; the compressed gas in the shunt pipe 11 enters the crushing cavity 17 through the impact pipe 18. Under the impact, collision, friction and shearing of high-speed airflow, the collision between magnesium powder raw materials and high-speed airflow becomes frequent and intense, and the magnesium powder raw materials are gradually crushed into fine particles.

Under the action of the high-speed airflow generated by the gas compressor 6, magnesium powder raw materials collide with each other, and magnesium powder raw materials also collide with the rotating grinding annular plate 43. Magnesium powder generated by the collision of magnesium powder raw materials in the crushing cavity 17 flows with the gas, and magnesium powder conforming to the mesh opening diameter of the conical filtering cylinder 22 flows into the discharge cavity 24; a magnesium powder containing structure is set inside the discharge port 25 in advance, and the gas containing magnesium powder inside the discharge cavity 24 is discharged into the preset magnesium powder containing structure from the discharge port 25. When the magnesium powder material larger than the mesh diameter of the conical filtering cylinder 22 falls onto the surface of the conical filtering cylinder 22 with the airflow, the controller 42 controls the driving motor 32 to start, and the driving motor 32 drives the driving shaft 33 to rotate through the power end; the driving shaft 33 drives the conical filtering cylinder 22 to rotate along the inner wall of the crushing cylinder 16 through the annular plate 21; the magnesium powder raw material attached to the surface of the conical filtering cylinder 22 is thrown away by the centrifugal movement, and the thrown magnesium powder raw material collides with the rotating grinding annular plate 43 and the bevel annular plate 44. The magnesium powder produced after the collision flows into the discharge cavity 24 through the mesh opening with the gas. In addition, the magnesium powder raw material splashed around the conical filtering cylinder 22 is crushed by the crushing plate 23 rotating at high speed, so that the raw material which may not be crushed into magnesium powder under the high-speed airflow may be blocked and crushed. On the one hand, the raw materials of magnesium powder may be prevented from block the mesh opening of the conical filtering cylinder 22 and affecting the passage of magnesium powder; on the other hand, the problem of uneven crushing of magnesium powder raw materials by the high-speed airflow may be made up, so that the magnesium powder raw materials may be crushed evenly.

The conical filtering cylinder 22 drives the bevel annular plate 44 to rotate inside the rotating grinding annular plate 43. Magnesium powder raw material is impacted by airflow at the joint between the annular plate 21 and bevel annular plate 44, the bevel annular plate 44 is arranged on the side of the conical filtering cylinder 22 close to the crushing cavity 17, the end of the bevel annular plate 44 near the conical filtering cylinder 22 is the highest point. The magnesium powder raw material slides downward along the inclined angle due to the action of gravity during the rotation, and drops onto the upper wall of the wear rubber layer 35. After the magnesium powder raw material in the crushing cavity 17 is crushed to the time specified by the user, the magnesium powder raw material with high hardness which is not pulverized in the crushing cavity 17 is crushed by combined gas. The shunt valves 12 are closed and the main gas valve 13 is opened, so that the main gas pipe 9 is in communication with the crushing cavity 17. The impact force of the gas discharged from the main gas pipe 9 without shunt is greater. With the continuous rotation of the bevel annular plate 44, the magnesium powder raw material falling onto the inner wall of the bevel annular plate 44 gradually rolls down to the upper wall of the wear rubber layer 35 through the opening at the bottom of the rotating grinding annular plate 43, and the compressed gas discharged from the main gas pipe 9 impacts the inner wall of the rotating grinding basin 27.

At this time, the controller 42 controls the driving electromagnet 41 to start, and the driving electromagnet 41 is electrified to generate magnetism; the tension spring 39 is shortened, and the upper wall of the impact iron block 40 is attached to the bottom wall of the impacted plate 37. The driving electromagnet 41 is fixed on the upper wall of the material pushing rack 36 and adsorbs the impact iron block 40 through magnetic. Under the deformation of the tension spring 39, the impact iron block 40 slides away from the bottom wall of the impacted plate 37 along the material pushing rack 36 through the impact rod 38. Subsequently, the driving electromagnet 41 is de-energized and demagnetized, and the tension spring 39 is elastically reset and drives the impact iron block 40 to impact the impacted plate 37 through the impact rod 38. Under the deformation of the wear rubber layer 35, the impacted plate 37 protrudes towards the crushing cylinder 16; the magnesium powder raw material on the inner wall of the wear rubber layer 35 bounces up and enters the high-speed airflow discharged from the main gas pipe 9 under the sudden impact. The controller 42 controls the driving electromagnet 41 to be energized intermittently, the magnesium powder raw material on the inner wall of the wear rubber layer 35 is bounced through the impact iron block 40, the high-speed airflow with high pressure drives the magnesium powder raw material with high hardness to collide with the rotating grinding basin 27 that is in rotation; the magnesium powder generated by the collision enters the discharge cavity 24 with the airflow. The remaining magnesium powder raw materials are located on the inner wall of the rotating grinding basin 27 under the impact of high-speed airflow, the rotating grinding basin 27 grinds the magnesium powder raw material by rotation, and gradually refines the magnesium powder raw material with higher hardness.

When the high-speed airflow discharged from the main gas pipe 9 drives the magnesium powder raw material bounced by the wear rubber layer 35 to impact the rotating grinding basin 27, hard magnesium powder raw material will cause the rotating grinding basin 27 vibrate during the impact. The rotating grinding basin 27 transmits the vibration to the interior of the tuning fork 29, and the tuning fork 29 is vibrated to generate sound. The controller 42 controls the noise sensor 31 to start, and the noise sensor 31 monitors the decibels produced by the tuning fork 29. When the noise sensor 31 monitors that the decibel inside the detection cylinder 30 disappears, indicating that the hard magnesium powder raw materials scattered on the upper wall of the wear rubber layer 35 are all refined. The above operations may be repeated for the next use.

It should be noted that in the present disclosure, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms “include”, “comprise” or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, object or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, object or device.

The present disclosure and its implementation have been described above, and this description is not restrictive. The embodiment shown in the attached drawings is only one of the implementations of the present disclosure, and the actual structure is not limited to this. In a word, if one of ordinary skill in the art inspired by it, under the premise of not departing from the design spirit of the present disclosure, any structural methods and embodiments similar to the technical solution without creative effort should all within the protection scope of the present disclosure.
