Beryllium metal is a rare light metal with numerous excellent properties, including low density, high melting point, large elastic modulus, high tensile strength, excellent thermal performance, good dimensional stability, small neutron absorption cross-section, and good X-ray transmission. It is an irreplaceable material in fields such as aerospace, aviation, electronics, and nuclear industries. Before beryllium metal can be applied, it needs to be processed into ultrafine powder, which requires the use of an airflow mill. Currently, the airflow mill is a common method for crushing and classifying beryllium metal, easily producing fine powder ranging from 3 to 74 microns with uniform particle size.

The airflow mill used for beryllium metal is an ultrafine grinding equipment that utilizes the kinetic energy of high-speed airflow to cause particles to collide and rub against each other for crushing. It features continuous production, large capacity, and a high degree of automation. It can be applied in various precision processing industries, such as electronic materials, chemicals, mining, and metal powders. Its biggest drawback is low energy utilization efficiency, so methods to reduce energy consumption and increase energy utilization should be sought to align with the trend and requirements of building an energy-saving and environmentally friendly society.

Sichuan Zhongjin Powder Equipment's airflow mill is a reliable assistant in the crushing and classification of beryllium metal, thanks to its inherent performance advantages:

1. Low energy consumption, more energy-efficient compared to traditional fluidized bed airflow mills.

2. Low-temperature, medium-free crushing ensures product purity and physical properties.

3. Wide range of crushable particle sizes, with adjustable finished product particle size within a certain range.

4. Built-in self-diverging micro-powder classifier, providing strong classification effects for ultrafine powders, resulting in narrow and more concentrated particle size distribution.

5. Negative pressure production, no dust pollution, excellent environment, with dust emissions not exceeding 15 mg/m3.

6. High degree of automation, enabling one-click start/stop, remote control capability when connected to a central control system, strong stability, and simple operation.

7. The company has specifically developed a compartmentalized offline dust removal and collection device for materials with high viscosity (such as white sugar, graphite, materials with high sugar or moisture content, and materials with severe agglomeration at sub-micron or nano levels), ensuring that the product does not adhere to the walls during operation and allows for smoother discharge.

8. For flammable, explosive, or easily oxidizable materials, inert gas can be used as the medium for fully enclosed crushing and classification, with the inert gas recycled and low loss.

From the above, it can be seen that the airflow mill is an effective means of processing beryllium metal. Practical cases have confirmed that in the preparation of beryllium metal, the airflow mill can easily produce fine powder ranging from 3 to 74 microns, enhancing the utilization value of beryllium metal.
