Embodiment

[0072]Seefigure 1 The present invention provides an automatic pulverizing apparatus of a neodymium iron boron magnet powder for sieving the neodymium iron boron magnet block formed by the NdFeB magnetic powder, thereby forming a magnetic powder having the same particle size range. Among them, the neodymium iron boron magnet block automatic pulverization device includes a vibration dispersing mechanism, a strand mechanism, a blast recovery mechanism, a screening collecting mechanism, a pulverizing mechanism, a detection mechanism, and a controller.

[0073]The vibration dispersing mechanism includes a dispersing cartridge 1, a screen one 2, and a vibration source 3. Screen One 2 is mounted in the dispersion cartridge 1 and is used to sieve the external input NdFe boron magnet block. The vibrating source 3 is mounted on the dispelling cartridge 1 and is used for vibrating screens 2. In the present embodiment, the dispersing cartridge 1 is a cylinder, both ends thereof. The dispelling car...

Embodiment 2

[0085]Seefigure 2 In this embodiment, the present embodiment provides an automatic pulverizing apparatus of a neodymium iron boron, which increases the electromagnet 17 on the basis of Example 1. The amount of electromagnet 17 is multiple, and the electromagnet 17 belongs to the blast recovery mechanism. The electromagnet 17 is mounted on the outer wall of the recovery housing 7. The controller is also used to activate the electromagnet 17 once every other preset time, so that the magnetine generated by the electromagnet 17 is adsorbed on the magnetic powder of the recovery housing 7 on the inner wall of the recovery housing 7, and the working time of the electromagnet 17 Turn off the electromagnet 17 at 2 times in a preset time.

[0086]Therefore, the NdFrobolam magnetic powder block automatic pulverization device provided in this example is capable of generating a magnetic field effect on the magnetic powder in the recovery housing 7, so that the magnetic powder is adsorbed on the in...

Embodiment 3

[0088]SeeFigure 3-7In this embodiment, a non-ferrous barrin pulverizing apparatus is provided, and the conveying mechanism is added based on the first embodiment. The conveying mechanism is used to deliver the NdFe boron magnet block rolled out from the outlet one 15 to the screen one 2. Among them, the controller is driven for each of the preset time three to transport the transport mechanism to a neodymium iron boron.

[0089]The conveying mechanism in this embodiment includes a lifting tub 19, a lifting assembly, an electromagnetic absorbing block 20, a rotating assembly, and a feed assembly. The lift bucket is located on one side of the pulverized housing 12 and receives a neodymium iron boron magnetic powder that rolls out from the outlet one 15. The discharge port 36 is opened on the side wall of the lifting tub 19, and the height of the discharge port 36 is higher than the height of the dispersing cartridge 1. The lifting assembly is mounted on the lifting tub 19 and is used to ...

Abstract

The invention discloses a neodymium iron boron magnetic powder block automatic crushing device and method. The device comprises a vibration dispersing mechanism, a mincing mechanism, an air blast recovery mechanism, a screening collection mechanism, a crushing mechanism, a detection mechanism and a controller. According to the device and method, neodymium iron boron magnetic powder blocks are vibrated and screened through the vibration dispersing mechanism, the neodymium iron boron magnetic powder blocks which are vibrated and screened are minced through the mincing mechanism, magnetic powderis blown to a recovery shell to be recovered through the air blast recovery mechanism, small powder balls and part of the magnetic powder can fall onto a second screen to be screened, the small powderballs can roll into a crushing shell from the second screen, the magnetic powder directly falls into a collecting barrel, the small powder balls can be further crushed under the rolling press actionof a roller set, a certain large magnetic blocks can also be crushed, and the magnetic powder can fall onto a conveying assembly and can be conveyed into the collecting barrel. According to the deviceand method, the crushing and screening efficiency can be improved, the utilization rate of magnetic materials can also be increased, the crushing effect of the neodymium iron boron magnetic powder blocks is improved, and the full-automatic circulation is achieved.

Description

[0001]The present application is Application No. CN201910899512.9, and the application date is 2019 / 09 / 23, and the present invention is a scaffolding apparatus for automatic pulverization devices and pulverization methods thereof.Technical field[0002]The present invention relates to an automatic pulverization device in the field of pulverization techniques and an automatic pulverization method thereof, and more particularly to a non-ferrite apparatus for a neodymium iron boron block and an automatic pulverization method thereof.Background technique[0003]The NdFeB magnet is a quadruple crystal crystal formed by neodymium, iron and boron. This magnet is today's permanent magnet that is second only to absolute zero magnets, and is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, headphones, and tools that supply power with batteries. NdFeB is divided into two types of sintered neaton boron and bonde...
