A kind of recycling equipment for NdFeB jet mill

Abstract

A kind of recycling equipment for NdFeB jet mill, including a cover body and a grinding part, the upper end of the cover body is provided with a separation port, the separation port is connected to the separation equipment of the next step process, and the inside of the cover body is a grinding chamber and a collection coarse The V-shaped bucket of the material, the grinding part is located at the connection between the grinding chamber and the V-shaped bucket, the feeding pipe is arranged in the grinding chamber, the air inlet pipe located under the grinding part is arranged on the V-shaped bucket, and the cover The top of the body is provided with a driving source, the driving source is connected with a main shaft that runs through the grinding chamber and the V-shaped bucket, the main shaft located in the grinding chamber drives the grinding part, and the V-shaped bucket is provided with a supporting column for supporting the grinding part. The outer ring of the main shaft located in the V-shaped bucket is provided with a return part connected to the grinding part, and the main shaft below the V-shaped bucket is connected with a lifting part. The invention provides that the coarse powder can be lifted when it is re-grinded. The height of a NdFeB jet mill recycling equipment that saves energy.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a recycling device for an NdFeB jet mill. Background technique [0002] Neodymium iron boron, simply speaking, is a kind of magnet. The difference from the magnets we usually see is that it is called the "magnet king" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force, and has the advantages of high energy density. NdFeB permanent magnet materials have been widely used in modern industry and electronic technology, thus making it possible to miniaturize, lighten and thin equipment such as instruments and meters, electroacoustic motors, and magnetic separation and magnetization. [0003] At present, the production process of NdFeB includes b...

Problems solved by technology

There is a problem here. The coarse powder is discharged from the bottom of the shell, lifted to the top of the grinding roller under the action of the bucket elevator, and re-enters the shell for re-grinding. Due to the elevated height of the coarse powder Higher, consumes a lot of energy, increases the production cost of the enterprise, and it is uncertain whether to upgrade, and manual care is required, resulting in inconvenient operation
