The Characteristics and Applications of Magnesium

Magnesium is a silvery-white, lightweight alkaline earth metal with the chemical symbol Mg and atomic number 12. As the eighth most abundant element in the Earth's crust, magnesium plays a significant role in various industrial fields due to its unique physical and chemical properties:

Lightweight: With a density of only 1.74 g/cm³, it is the lightest of all industrial metals.

Mechanical Properties: It has excellent specific strength and specific stiffness.

Chemical Reactivity: It readily reacts with oxygen to form an oxide film, and in powder form, it has high reactivity.

Applications: Industries such as aerospace, automotive manufacturing, 3C products, pharmaceuticals and chemicals, and pyrotechnics widely use it.

Introduction to Vacuum Pneumatic Conveying System

Magnesium powder, as a special form, plays a significant role in fields such as chemical catalysts, pyrotechnic manufacturing, and metal reducing agents. However, its transportation process requires special attention to safety measures such as explosion prevention and oxidation prevention.

A vacuum pneumatic conveying system is an automated equipment that uses the principle of vacuum negative pressure to convey powder and granular materials. It is particularly suitable for the closed transportation of materials that are prone to oxidation and explosion, such as magnesium powder.

Working Principle

1. Vacuum Generation: A vacuum pump or a Roots blower creates a vacuum in the conveying pipeline.
2. Material Ingestion: Under the negative pressure, magnesium powder is sucked from the storage bin or container into the conveying pipeline.
3. Gas-Solid Separation: The material enters the receiving bin, and gas-solid separation is achieved through a filter.
4. Continuous Operation: After the conveying is completed, the system is depressurized and enters the next working cycle.

Technical Features

Sealed Conveying: The fully enclosed system effectively prevents magnesium powder from coming into contact with air, reducing the risk of oxidation and explosion.

Dust-free Operation: Eliminates dust leakage and improves the working environment.

Automated Control: PLC control enables precise and timed conveying, seamlessly integrating with production lines.

Modular Design: Flexible configuration based on different process requirements.

Safety and Explosion-proof: Optional explosion-proof motors, nitrogen protection, and other safety devices are available.
