Description

A kind of NdFeB superfine powder pretreatment device

technical field

The invention relates to the field of neodymium-iron-boron roasting technology, in particular to a neodymium-iron-boron ultrafine powder pretreatment device.

Background technique

NdFeB magnetic materials, known as "Magnetic King" due to their excellent magnetic properties, are widely used in many fields, but in the production process of NdFeB magnets, NdFeB superfine powder waste will be generated, and ultrafine NdFeB magnets will be produced. The powder ratio accounts for more than 1% of the output. In order to save resources and improve the comprehensive utilization rate of waste resources, the recycling of NdFeB ultrafine powder has important practical significance and has a broad prospect.

In the current technology, some powder particles with smaller particle size will be generated during the production and processing of NdFeB products. In the industry, powders with such particle size in the set value are called NdFeB ultrafine powder. When the NdFeB ultrafine powder is scrapped, its particle size is small, so the contact area with the air is large. When the NdFeB ultrafine powder is concentrated in the air, spontaneous combustion or even explosion can occur. When collecting NdFeB fine powder, the air isolation method is used for closed collection, stored in a sealed container, and then transferred to special combustion equipment for manual combustion treatment, and the rare earth elements in NdFeB are recycled. The whole process has a long cycle, and the workers are labor-intensive. They must always handle the fine powder with great care and concentrate on processing.
