Description

Technical Field

[0001] The invention relates to the technical field of metal powder processing, in particular to a processing device for metal powder production. Background Art

[0002] Metal powder is a loose substance, and its performance comprehensively reflects the properties of the metal itself, the properties of individual particles, and the characteristics of particle groups. Metal powder can be used as raw material for powder metallurgy products, and can also be used directly. It has high application value. In the process of metal processing, grinding equipment is usually used to achieve metal processing to obtain metal powder.

[0003] The metal powder processing device in the prior art usually needs to be subjected to multi-stage grinding to obtain powder that meets the requirements. During the grinding process, as the grinding plate continuously rotates and grinds, the actual friction temperature between the grinding plate and the grinding seat is too high, causing the surface of the grinding equipment to be too hot during the grinding process. The high temperature environment affects the strength of the metal powder and even causes oxidation, causing the metal powder to be compressed and agglomerated during the grinding process. At the same time, the existing equipment cannot achieve cyclic grinding. On the other hand, the excessively high temperature causes the overall temperature of the equipment to increase, affecting the service life of the equipment. After the grinding is completed, it needs to be left to cool down, and the waiting time for cooling down is relatively long. Summary of the invention

When the conical grinding body 5 rotates under the drive of the driving shaft 3, the primary powder in the discharge trough 18 is discharged through the discharge hole 19. A slope 20 is provided at the bottom of the discharge trough 18 to enable the powder to be automatically transported downward under the vibration of the motor. Since the loading hopper 7 is fixed, the conical grinding body 5 will grind the powder remaining in the gap between the inner side of the loading hopper 7 and the grinding trough 8. The ground powder will be discharged along the conical grinding body 5 to the powder storage chamber 16. During the grinding process, the conical grinding body 5 and the loading hopper 7 can be cooled by injecting water into the surface of the conical grinding body 5.
